Nothing heavy duty and I didn't run NHRA sanctioned races because that's a much bigger commitment of both time and money. When there wasn't a sanctioned race, they would open the track to all us weekend warriors who just wanted to see how fast we were. For $5 per pass, you could run whatcha brung. I got a 10.9 second 1/4 mile @ 125mph on my Kawasaki 750 Turbo, and ran low to mid-12's @ ~110 with the Camaro. The goal was to not break anything. Sometimes that bar was too high. I loved it. We all helped each other in the pit if something did break.
