I haven't got slicks for the car yet but...
Techniques for launching:
Pull up to the water box, spin the tires through to get them wet, roll past the water box. Set e brake on. While left foot on the brake, right foot on gas bring the rpms up and just slam the hammer down and maybe have someone spot you to see that both tires are spinning... Give the steering wheel a little shake back and forth while in burnout and then let the e brake go.
When at the line, may or may not apply for s/c cars but for turbo cars you want the brakes to hold the car back as much as you can. To do this some people have pulled up to the line and when staged put the car in nuetral, give it a quick rev, hold the brake as far down as you can, shift to drive and then you can build more boost after you have raised the brake pressure up. From there on out its tires/air pressure/track surface and getting a feel for the pedal.
170,000 miles, you may want to do a thorough inspection, or just find out at the track...lol
