Tires and clutch setup?
Hopefully I'm not being a pest. Just got my 30r setup together and saving some teething issues. I'm nearly convinced the short geared 6mt is the devil. I've tried launching in both 1st and 2nd and a 1.8x is the best I've gotten on my bfg kdw2. This is on the two step building 8-10psi at 4k. I blow em off and fall flat shifting to fifth.
I have other issues I'm working out with boosting over 21psi but the car runs good. It's definitely faster than I am. 1.86 60', 7.87 @ 89 1/8 and 12.12 @ 115 is my quickest pass to date. I wanna share your company in the tens with my full weight pig.
