Track days are the purest expression of what a performance vehicle can do — no speed limits, no stop signs, just you, your car, and a ribbon of asphalt. But heading to Willow Springs, Auto Club Speedway, or Streets of Willow without properly preparing your vehicle isn’t just a recipe for poor lap times; it’s a safety risk. High-speed, high-load driving in summer heat puts mechanical systems under conditions most vehicles were never designed to sustain.
At Galpin Auto Sports, we prep performance vehicles for exactly these conditions. Here’s what actually matters for summer track day preparation.
Brakes: The Most Overlooked Track Upgrade
Street brake pads are formulated for city driving. They work at low temperatures and recover between stops — but on track, they never cool down. The result is brake fade: a terrifying softening of pedal feel as your pads and fluid approach their thermal limits. Upgrading to a performance brake compound rated for track temperatures, combined with fresh high-boiling-point brake fluid, is the single most important safety upgrade you can make.
Slotted or drilled rotors improve heat dissipation and help purge gas buildup from pad off-gassing under sustained load. Stainless braided brake lines eliminate the mushy pedal feel caused by rubber lines expanding under pressure.
Our performance services include full brake system upgrades from compound selection through big brake kit installation.
Tires and Wheels: Where Lap Times Are Made
Your tires are the only thing connecting your car to the track. A proper track tire — a high-performance summer compound or dedicated track tire — will transform your lap times more dramatically than almost any other single upgrade. The difference in grip between a worn all-season and a fresh performance compound is measured in seconds per lap.
Wheel selection matters too. A lighter wheel reduces unsprung mass, improving suspension response and reducing rotational inertia. Even a modest reduction in wheel weight has measurable effects on acceleration, braking, and handling.

Suspension Tuning for the Track
Track driving demands a very different suspension tune than street driving. Lower ride height improves aerodynamic stability and lowers center of gravity. Stiffer spring rates reduce body roll in corners. Adjustable dampers let you dial in compression and rebound for the specific characteristics of the track you’re running.
Corner weighting — adjusting spring perches to equalize weight distribution across all four corners — is a precision suspension setup technique that can meaningfully improve handling balance. This is the kind of work that separates a properly set-up track car from one that was just lowered and left. Our suspension services team has experience setting up vehicles for everything from HPDE events to competitive club racing.
Engine and Cooling: Managing Heat at Full Throttle
An engine running at full throttle for extended periods in summer heat will stress every component of your cooling system. Before a track day, inspect your cooling system for any signs of deterioration — cracked hoses, low coolant level, a marginal thermostat. Better yet, flush and replace your coolant with a track-rated formulation.
Beyond the stock cooling system, consider an upgraded radiator for additional thermal capacity, an oil cooler to keep engine oil in its optimal temperature range, and an air-to-air intercooler if you’re running forced induction. Power delivery on a turbocharged or supercharged car degrades noticeably as intake temperatures climb.
