i dont have one, and i dont think other people due, as not many people drag on BL straight, but here is a few tips
1. Make the gear ratio's shorter than normal
2. lock the rear diff
3. make the rear tyres the lowest possible pressure, and put the car on Supers, also make the camber angle slighty negative
4.make the back soft and the front hard
Thats all i have for the moment, now im going to sleep byebye
