"You can't just build a car and expect it to be fast. It takes work. You have to practice, practice, practice, take data and more practice. Only then will you, maybe, make a fast car. You can't just build a fast car by adding parts." - Michael Chang, Owner of Evasive Motorsports.
When it comes to car setup there are a number of things to consider. Based on their extensive track time and excellent results we knew the experts from Evasive Motorsports in La Puente, CA would be more than qualified to break down a good time attack setup. If you want to setup your car to attack the clock, get ready to take some notes. Let's take a closer look at Evasive's revised street class S2000 to see what makes this record breaker tick.
Brakes
Last but certainly not least, brakes contribute a lot to fast lap times. In time attack it's not just how quickly you can accelerate that counts but also how quickly you can stop, and for how long. Brake fade is a driver's worst nightmare and making sure you have the right fluid and correct rotor size for the job is paramount. Brake pad compound is another area that takes a lot of thought and should be matched to the tire compound for optimal performance.
"We upgraded the brakes to an AP Racing brake system. It takes heat a lot better than an OEM sized rotor. We also switched to Project Mu 999 pads all around." - MC
Aerodynamics
At first glance the Voltex kit on this AP2 (the first and only one anywhere in the world at the time of writing) makes the car look like something you'd see in the unlimited class. Looks can be deceiving as this is actually a street class car, but despite the lower speeds seen by the car the aero kit still plays a huge role in the car's overall performance. Why? A good aero kit does a number of things for a car. Aero can increase downforce allowing faster cornering speeds while reducing drag for better acceleration. Added stability and cooling capabilities are other benefits. With the use of this kit, Evasive recorded an average increase of 6mph in turns, enough to shave 2 seconds off the previous configuration's lap time!
"We worked directly with Voltex to develop a kit for the S2000 since we felt it was something needed in the US. For a car that's so underpowered aerodynamics are often overlooked. Our results this week demonstrated that a well-balanced car can be as fast as a 500hp Evo" - MC
