I bought those covers in the grid pattern for both my CMC Camaro and C5 Z06 street car and love them. When I had wet feet my foot would slip off the brake/clutch pedals in the Z06. I bought them for that first then acquired the CMC car and installed them there as well. I did shim the accelerator cover up with a chunk of OSB to get the height right. Now you get to learn to brake with the ball of your foot. Start doing it on your DD too so it's second nature in the race car. The blip is nothing more than locking your ankle and rocking your knee to keep the car from jerking when you start. After that it'll come more naturally.
