I am an experienced competitor in the Ontario Time-Attack series but will be new to the Type R for next year. The car will be basically bone stock except for improved camber, brake pads, tires and wheels. I have a few questions for those who compete with their cars, not just HPDE although you are welcome to chime in. The car needs to stay street legal and at this stage, will be on stock springs and shocks.
1) With stock springs, what sort of camber are you running with 200 UTQG tires such as RE-71Rs or Yoko A052s? The Hardrace all joints have already been ordered.
2) What rear brake pads do you run? I am comfortable with my choice of front pads and am a firm believer that the rear should not be the same compound given the greater weight transfer that occurs with better tires. In some previous cars, I have just used stock OEM rears but feel that a minor upgrade would be good.
3) Probably most important, what sort of RPM do you shift at for max performance? 2 of the tracks I frequent will likely need a shift at the end of the fastest straight (I already know that at least 1 will) and the question becomes, is it worthwhile to run to the limiter to avoid another shift up and then down again or should I just shift earlier?. I don't like running up to the rev limiter and it seems the stock motor starts to drop in power after 6300 to 6500. BTW, the rev limiter cuts in at 7000 doesn't it? Fortunately the torque peak is significantly lower so the power band is pretty wide. The other issue that complicates this is the diameter of the tires I finally decide on and how fast I can get out of the preceding corner.
