The Essential HPDE Tool Prep Kit for DIY Enthusiasts

You signed up for your first HPDE event. Congratulations! You’re about to find out what your car was really made to do. But here’s something no one tells you at driver meetings: the track doesn’t have a pit crew. You are responsible for making any changes, tightening, swapping, or fixing that needs to be done between sessions. And standing in the paddock and asking to borrow a 17mm socket gets old really quickly.

We wish someone had given us this guide before our first event. It’s not a made-up garage build; it’s a real set of tools that will help you get through tech inspection, tire changes, brake checks, and the inevitable “what’s that noise?” moment between sessions.”moment” between sessions. We have bought, used, and put every single thing on this list through the wringer at the track. No extra stuff, just the gear that deserves to be in the trailer.

We don’t care if you drive a weekend Miata, a modified BMW, or grandma’s Camry with race pads; these tools will keep you from having to turn wrenches in a hurry. Let’s get started.

The Cordless Pit Crew: Milwaukee M18 Power Tools

A good cordless impact setup is a must if you want to do your own track prep. We put everything we had into the Milwaukee M18 FUEL platform, and it has completely changed the game. One battery system for many tools, and no cords to trip over in the paddock.

Milwaukee M18 FUEL 1/2” Compact Impact Wrench

This is your wheel gun. The Milwaukee M18 FUEL 1/2” Compact Impact Wrench can break nuts with 250 ft-lbs of torque in a package that is less than 5 inches long. The lug nuts come off easily, and the 4-mode drive control makes sure you don’t over-torque your studs. Small enough to fit in tight wheel wells and strong enough to break loose the most stubborn fasteners. Every time we have an event, this is the first tool we take out of the box.

Milwaukee M18 FUEL 1/4” Hex Impact Driver

The Milwaukee M18 FUEL 1/4″ Hex Impact Driver is the tool you need for everything else. This thing can handle anything that needs a hex or socket adapter, like aero kits, splitter bolts, skid plates, and brake caliper brackets. The variable-speed trigger lets you work with small fasteners without stripping the M6 bolts on your undertray. When you add the adapter set below, you basically have a cordless ratchet on steroids.

Milwaukee M18 REDLITHIUM HIGH OUTPUT XC6.0 Battery 2-Pack

Without power, power tools don’t work. The M18 REDLITHIUM HIGH OUTPUT XC6.0 Battery 2-Pack will keep your impact wrench and driver going all weekend. These batteries last longer and run cooler than regular packs. Plus, having two means that one is always charging while you work. We promise that a dead battery is the worst thing that can happen when you need to change brake pads between sessions.

The Socket and Wrench Arsenal

This is what you need most for your trackside toolkit. You need a variety of wrenches, sockets, and ratchets that can handle everything from small caliper bleeders to huge axle nuts. We run this:

DURATECH 3-Piece Ratchet Set (1/4”, 3/8”, 1/2”)

Ratchets are an important part of any toolkit, and this DURATECH 3-Piece Ratchet Set has 90-tooth mechanisms for all three drive sizes. When you’re working in tight spaces around brake calipers or suspension parts, that 4-degree swing arc is a huge help. The chrome vanadium steel is fully polished, and the quick-release button works, unlike some cheap sets. These are the cars you drive every day.

Capri Tools 3/8” Drive Semi-Deep Impact Socket Set (Metric, 15-Piece)

The Capri Tools Semi-Deep Impact Socket Set in 8–22mm has most of the fasteners you’ll find on any modern car at the track. The semi-deep profile lets you reach farther than standard sockets without being as heavy as deep sockets. The 6-point WaveDrive design holds fasteners tightly and stops them from rounding. This is something you’ll be glad to have when you’re trying to fix a stuck brake caliper bolt at 2 p.m. in the summer heat.

1/2” Drive Deep Impact Socket Set (11-Piece, 27–38mm)

Standard socket sets don’t work when you need to get into axle nuts, spindle nuts, and hub assemblies. This 1/2″ Drive Deep Impact Socket Set comes in jumbo metric sizes from 27mm to 38mm, which fills that gap. You need these big guys if you’re doing heavy suspension work, CV joints, or bearing work at the track or at home.

3/4” Drive Impact Socket Set (8-Piece, 26–38mm)

This 3/4″ Drive Impact Socket Set in CR-MO steel has the torque capacity you need for really heavy-duty jobs like changing hub nuts on trucks, big brake conversions, or heavy-duty suspension work. This is a special set, but you can’t use anything else when you need it.

DURATECH 15-Piece Combination Wrench Set (Metric)

A good set of combination wrenches can help when a ratchet won’t fit. The DURATECH 15-Piece Combo Wrench Set comes with chrome vanadium steel wrenches that range in size from 8mm to 22mm. The box end has 12 points and a 15-degree offset. It comes in a nice roll pouch that fits in your toolbox without taking up too much room.

CRAFTSMAN All Steel Adjustable Wrench Set (2-Piece)

An adjustable wrench is the best backup plan for everyone. The CRAFTSMAN All Steel Adjustable Wrench Set comes with two sizes and is made of I-beam steel, which can handle a lot of torque. These will help you out when you find a strange fastener that doesn’t fit any of your metric tools.

LEXIVON Hex Bit Socket Set (13-Piece Metric)

There are hex-head (Allen) bolts all over modern cars, including on the brake calipers, interior trim, and aerodynamic parts. The LEXIVON Hex Bit Socket Set comes in sizes 2 to 14 mm and lets you use a ratchet instead of L-keys in tight spaces. S2 alloy steel bits that have been properly hardened so they won’t round out.

Amazon Basics 26-Piece Hex Key Allen Wrench Set

The Amazon Basics 26-Piece Allen Wrench Set has both SAE and metric sizes and ball ends that let you work at an angle. This set is great for when you need a regular Allen key, like for a set screw or something deep in a pocket. Low-cost protection for your tools.

Impact Accessories: Extensions, Adapters, and Torque Sticks

The accessories you use with your impact wrench will determine how useful it is. These are the parts that let your power tools hit the fasteners they need to hit.

Neiko 3/8” Drive Impact Extension Bar Set (3-Piece)

The Neiko 3/8″ Impact Extension Bar Set comes in lengths of 3″, 5″, and 10″ and gives you the reach you need for your 3/8″ drive tools. Steel with a black protective coating. Necessary for getting to brake caliper bolts and suspension work that the ratchet can’t reach on its own.

Neiko 1/2” Drive Impact Extension Bar Set (3-Piece)

Same idea, but with a bigger drive. The Neiko 1/2″ Impact Extension Bar Set comes with 3″, 6″, and 8″ handles and can handle heavier things like lug nuts that are deep in wheels, hub bolts, and anything else your 1/2″ impact wrench needs a little more reach for.

Neiko Impact Socket Adapter Set (5-Piece)

With the Neiko 5-Piece Socket Adapter Set, you can use different sizes of drives together. You can use your 1/2″ impact with 3/8″ sockets or your 1/4″ hex impact driver with any socket. Chrome vanadium steel is made to handle heavy loads. This little set is one of the most useful things in our toolbox.

ARUCMIN 1/2” Drive Torque Limiting Extension Bar Set (10-Piece)

Torque sticks are the unsung heroes of changing wheels on track days. The ARUCMIN Torque Stick Set comes with color-coded sticks that range from 65 to 150 ft-lbs. You can use your impact wrench to install lug nuts to a safe, consistent torque without over-tightening. Put one between your impact and socket, and it will bend at the right amount of torque. It won’t replace a final check with a torque wrench, but it gets you close quickly and stops your rotors from bending.

Wheel and Lug Nut Tools

Tire changes are probably the most common thing to do at the track. You will always be pulling wheels, whether you are checking tire pressures, adjusting camber, or using a dedicated set of track wheels. This is what makes the process go smoothly:

Neiko 1/2” Drive Impact Flip Socket Set (4-Piece)

The Neiko Impact Flip Socket Set has dual-sided sockets that fit the six most common lug nut sizes. You can flip them over to get a different size. You can use it with breaker bars, torque wrenches, and impact tools. It comes in a case that keeps everything neat. Something you wish you had bought sooner.

ARES 17mm Non-Marring Lug Nut Socket

If you have aftermarket wheels with exposed lug nuts, you know how easy it is to scratch them with a regular chrome socket. The ARES 17mm Non-Marring Socket comes with a sleeve that keeps your lugs and rims looking clean. So you can always grab the right one, they are color-coded and laser-etched.

ARES 19mm Non-Marring Lug Nut Socket

Same thing as above, but in 19mm. If your car has 19mm lugs (like BMW and Honda owners), you need the ARES 19mm Non-Marring Socket. While you’re taking them off and putting them back on all weekend, keep those nice wheels safe.

WORKPRO 24” Dual-Drive Breaker Bar

The WORKPRO 24″ Breaker Bar gives you the mechanical edge you need to break loose even the most stuck fasteners when your impact wrench says “nope.” The dual-drive head can turn to get into tight spaces. The chrome vanadium and chrome moly steel construction means it won’t bend or twist when you put your weight on it.

Lifting and Support: Getting Your Car in the Air

If you can’t safely lift your car off the ground, you can’t change the wheels, check the brakes, or look under the car. A good jack and a strong pair of stands are the most important tools. Don’t skimp on this.

Pittsburgh 2.5 Ton Low-Profile Aluminum Racing Floor Jack

In the grassroots motorsport community, the Harbor Freight Pittsburgh 2.5 Ton Low-Profile Racing Floor Jack is one of the best-kept secrets. With the dual parallel Rapid Pump system, you can get your car up in just three pumps. No more pumping for hours while you sweat in the paddock. Because it is low-profile, it can slide under cars that other jacks can’t reach. The aluminum construction makes it light enough that you won’t hurt your back when you load it into the trailer. The universal joint release mechanism lets you go down smoothly and in control from any handle position. At this price, there’s nothing else that has speed, low clearance, and portability all in one.

ESCO 3 Ton Performance Shorty Low-Profile Jack Stands (Pair)

When your car is up, it needs to stay up safely. The ESCO 3 Ton Performance Shorty Jack Stands are made just for cars that are lowered or have low clearance. The shorty profile starts at only 11 inches, so they really do fit under your car when the floor jack is at its lowest point. With seven adjustable positions that go up to 17 inches, you have a lot of options. The flat rubber saddle that comes off protects your pinch welds and frame rails better than traditional curved-top stands. The two stands can hold 6 tons, which is more than enough for anything you would bring to an HPDE event. They have been tested by ASME and are built to last. You shouldn’t cut corners when it comes to your car’s safety, and these give you a lot of peace of mind.

Essential Hand Tools

Power tools are great, but sometimes you need the accuracy and feel that only hand tools can give you. These are the things you’ll always want to grab and go:

Klein Tools 14-in-1 Screwdriver/Nut Driver

The 14-in-1 Screwdriver from Klein Tools is like a Swiss Army knife for your toolbox. Phillips, slotted, square, Torx, and combo bits, plus nut driver sizes—all in one impact-rated handle with rare earth magnets. Blade length can be changed to get to hard-to-reach places. We keep this one tool in our back pocket at every event, and it replaces a whole set of screwdrivers.

WORKPRO 7-Piece Pliers Set

With the WORKPRO 7-Piece Pliers Set, you get groove joint, long nose, slip joint, linesman, and diagonal pliers. These are all the tools you need to grab, pull, cut, and bend things at the track. Double-dipped comfort grips and a surprisingly strong build quality for the price. You will use these more than you think.

WORKPRO 7” Locking Pliers (Vice Grips)

The WORKPRO Locking Pliers lock on and hold tight when you need a third hand or have a stripped bolt. Great for holding heat shields, clamping brake lines, or grabbing anything that doesn’t want to work. Chrome vanadium steel jaws with a built-in wire cutter.

TEKTON 12” Angled Pry Bar

The TEKTON 12″ Pry Bar is made in the USA from heat-treated steel and has a striking cap on the end for when you need to use force. This thing does a lot of useful things, like prying brake caliper brackets, popping clips, and using leverage on stubborn parts. The black oxide finish won’t chip, and the polypropylene handle doesn’t mind brake fluid or solvents.

HORUSDY 5-Piece Hammer Set

There are times when you just have to hit something. The HORUSDY 5-Piece Hammer Set comes with a sledge, a rubber mallet, a cross peen, and ball pein hammers. All of them have fiberglass handles that absorb shock and make your arms less tired. The rubber mallet is worth it on its own for putting wheel hubs in place and getting stubborn parts to move without breaking them.

Neiko 2 LB Dead Blow Hammer

The Neiko 2 LB Dead Blow Hammer is the best tool for strikes that don’t bounce back. Steel shot inside the head stops the ball from bouncing back, so every swing goes exactly where you want it to. The poly jacket protects the work surface, and the checkered grip keeps it in your hand. Great for getting stuck rotors loose or putting bearings in place.

Telescoping Magnet Pick-Up Tool Set (4-Piece)

Did you drop a bolt into the engine bay? Did the socket fall into the fender? You don’t have to take apart half of your car to get a $0.50 fastener with the Telescoping Magnet Pick-Up Tool Set. There is a 10-pound magnet on a telescoping wand, a flexible magnet sweeper, and a grabber claw. It’s one of those things you don’t think about until you really need it, and then it’s a lifesaver.

Supplies, Safety, and Comfort

Track days are long, hot, and hard on your hands and knees. Don’t forget about the things that keep you safe and comfortable while you work:

Heat-Resistant Nitrile Gloves with Cotton Liners

These disposable gloves that don’t get hot are a must-have at the track. You get 100 heavy-duty 10-mil black nitrile gloves and 4 cotton liners for when you have to work with hot brakes, exhaust parts, or anything else that has been sitting in the sun. The cotton liners keep your hands from getting too hot without making them less flexible, and the non-slip grip is great when your hands are sweaty or oily.

Gorilla Grip Kneeling Pad

Your knees will be grateful. The Gorilla Grip Kneeling Pad is very thick, keeps water out, and really cushions your knees when you kneel on hot asphalt. This pad makes working on the track a lot easier, whether you’re checking tire pressures, looking at brake pads, or just trying to see under the car. It’s light enough to throw in your bag and forget about until you need it.

Amazon Commercial Electrical Tape (6-Pack)

You might be surprised at how often you need electrical tape at the track. It’s the duct tape of the motorsport world: it holds wires together, marks torqued bolts, tapes down a GoPro cable, and patches up a torn boot. This 6-pack gives you a lot to burn through and share with your neighbors in the paddock.

Keeping It All Together: Tool Storage

If these tools are just lying around in the trunk or in the paddock, they won’t do you any good. You need a plan:

ToughBuilt StackTech XL 3-Drawer Tool Box

The ToughBuilt StackTech XL 3-Drawer Tool Box is the place where all of this gear is stored and used. The lid is IP65-rated, so it keeps dust and water out, and the three self-latching drawers let you get to your tools without having to unstack them. It has wheels that can go over any type of terrain and can carry up to 250 pounds. As your collection grows, the StackTech system lets you add modular boxes on top. This is the part that makes a messy pile of tools into a neat trackside pit setup.

Leveling Up: Data and Performance

It’s time to start getting better at driving once your car is ready and your tools are set. That’s when data comes in:

Garmin Catalyst 2 Driving Performance Optimizer

The Garmin Catalyst 2 is the most useful “tool” on this list because it makes you faster, not just your car. It goes in your cockpit and uses Bluetooth to send audio coaching to your helmet headset or car stereo in real time. It tells you exactly where you’re wasting time: “Brake later into Turn 3,” “More throttle at the apex of Turn 7.” After each session, you get a detailed breakdown of your line, speed trace, and the best ways to improve. The camera that comes with it records 1080p video with data overlays that are synced with the time, so you can watch your driving at home. This is the one piece of technology you should buy for HPDE. In one weekend with the Catalyst, you’ll learn more than you would in three weekends without it.

Final Thoughts: Build It Over Time

We understand that this is a lot of stuff. You don’t have to buy everything all at once. If this is your first event, start with the basics: a ratchet set, an impact socket set, lug nut tools, a breaker bar, electrical tape, gloves, and a kneeling pad. That will help you get through your first weekend. As you learn what your car needs, add tools as you go.

The Milwaukee power tool setup makes things a lot easier, but a lot of people get through their first season with just hand tools. The Garmin Catalyst is an investment in your driving, not your car, and once you get hooked on going faster, it’s worth every penny.

The point is that having the most expensive tools isn’t what being ready at the track is all about. It’s about having the right tools, knowing where they are, and being able to deal with whatever your car throws at you between sessions. Get your kit together, learn about your car, and go for those lap times.
