Best Brake Pads for Autocross & HPDE
Brake fade is the single most predictable and preventable way to have a bad first track day. Your stock pads were designed for street driving — light, progressive stops from 45 mph. They were not designed for repeated hard braking from 100+ mph at a road course, or the short, aggressive brake zones in a hot autocross parking lot in July.
Upgrading brake pads is the first performance modification most experienced drivers recommend. It's also one of the most confusing purchases because of the sheer number of compounds available. This guide cuts through it.
Why Stock Pads Fail on Track
Brake pads generate friction by pressing a friction material against the rotor. That friction generates heat. Street pads are designed to work well from cold (your driveway at 40°F) up to moderate temperatures (~400–600°F). They're optimized for quiet, low-dust, comfortable street use.
On track — even at a beginner HPDE event — brake temperatures routinely exceed 1,000°F. At those temperatures, street pads undergo a process called brake fade: the friction material breaks down, outgasses, and the pad literally glazes over. You'll feel it as a soft, mushy pedal that requires more force for less stopping power. At the extreme end, the brake pedal goes to the floor.
Drivers at HPDE 1 events regularly experience brake fade on their second session even in low-powered cars. The continuous nature of road course driving — even at moderate speeds — generates far more heat than street driving ever does.
Brake fluid is equally critical. DOT 3/4 street fluid is hygroscopic — it absorbs moisture over time. Wet fluid has a boiling point 100–200°F lower than fresh fluid. Always flush with fresh DOT 4 fluid before a track event. See the First Track Day Checklist for the full pre-event brake procedure.
Understanding Temperature Ratings
Performance pads are spec'd with temperature ranges — a minimum operating temperature (where they develop good bite) and a maximum temperature (where they fade). Understanding these ranges helps you pick the right pad for your event type:
| Pad Type | Operating Range | Cold Bite | Best Use |
|---|---|---|---|
| Street (OEM) | Ambient – 600°F | Excellent | Street only |
| Street Performance | 200 – 900°F | Good | Autocross, light HPDE |
| Track / Club Sport | 400 – 1,200°F | Moderate | HPDE, GridLife, TT |
| Race | 700 – 1,600°F | Poor – needs warm up | Wheel-to-wheel, sustained track only |
The key insight: autocross and HPDE require different compounds. Autocross runs are 60–90 seconds long. Your brakes rarely reach sustained high temperatures — cold bite matters more than high-temp fade resistance. HPDE is the opposite: sustained 20–30 minute sessions mean your brakes heat-cycle repeatedly, and you need pads that perform at elevated temperatures without fading.
Best Pads for Autocross
For autocross, prioritize cold bite and modulation. You want the first hard stop of each run to feel consistent, not wooden. These pads live in the street-performance-to-club-sport range:
The Hawk DTC-60 is the community standard for good reason. It has enough cold bite to work from the first stop of the first run, performs well through a full autocross day, and doesn't destroy rotors. The DTC line (Dynamic Torque Control) is designed specifically for track use. The 60 is the milder compound — the DTC-70 runs hotter and is better suited for sustained road course work.
If you're not ready to commit to a dedicated track compound, EBC YellowStuff is a solid dual-use pad. You can daily drive on them, and they'll handle a full day of autocross without fading. They won't perform at sustained road course temperatures, but for parking lot autocross they're a legitimate step up from OEM.
Best Pads for HPDE & Road Course
For road course HPDE, sustained high-temperature performance becomes the priority. These pads need to survive 20–30 minute sessions with hard braking at the end of long straights. Cold bite matters less because the first lap is always a warm-up lap.
The XP10 is optimized for cold bite — great for autocross. The XP12 runs at higher temperatures and is the better all-rounder for drivers who do both autocross and HPDE. If you're only going to run one compound for both, XP12 is the pick.

What About Rotors?
Unless your rotors have deep grooves, cracks, or are below minimum thickness, you don't need to upgrade them for HPDE use. Stock rotors are fine for entry-to-mid level track use. Slotted rotors (like Stoptech Sport or DBA 4000) can help degas pads faster but are not necessary.
Don't use drilled rotors on track. The drills create stress risers that can cause rotors to crack under the thermal cycling of repeated hard use. Drilled rotors are a street aesthetic item, not a track performance item.
Flush your brake fluid (fresh DOT 4 or DOT 5.1), install your new pads, bed them in with 8–10 medium stops from 40 mph before you track the car, and confirm you have at least 50% pad life. See the full First Track Day Checklist.
