Racecar

Our racing store at DiscoveryParts.com has every piece of racing gear you could possibly need. From the quick disconnect OMP suede steering wheel that makes getting in and out of your Racetech carbon fiber head containment seat fast, to the Longacre tire pyrometer that tells you exactly what every single suspension modification has accomplished, we have them all.

Systems. That is how a racecar makes it to the top of the podium. DiscoveryParts GT2 Datsun 240Z won the NASA-SE Enduro Championship 2 years in a row. Let's take a look at just the brake system. Castrol SRF ReAct provides the force to squeeze the Hawk DTC pads against the rotors to stop consistently, lap after lap, hour after hour. Brake ducts feed the 3" brake ducting to the back of the rotor to keep temperatures in check during the long July and August races.

The racing experts at DiscoveryParts.com have the knowledge and experience to make sure your racecar performs at its best using components that work together. Have a dual-purpose car that takes you to the job that pays for that track weekend? Let us help you with a quickly removable harness that keeps you safe on the track, but is removable on Monday to take the kids to practice.

Purchased your first trailer and can now run a track only alignment? Let us help you get the best from Longacre to set your chassis perfectly. How much better is it? Let's look at Data Acquisition Systems from AiM to leap ahead in chassis set-up and driver improvement. DiscoveryParts.com offers the racer the best from companies like Hawk, Sparco, Schroth, G-Force, Aim, Racetech, SPA, Joe Gibbs Racing, ATL, Simpson, Longacre, MOMO, FuelSafe, and more.
