Been a while since i've posted or been on the VMF but back daily reading all your posts
I've been doing some track time with my 69 Fastback but have never attempted running a slick on the back mainly due to the car being stock underneath... I've got a fairly healthy 428 wiht 4spd toploader and a 3:91rear going to Estimate about 400-450HP at the rear wheels. I'd love to put a good sticky tire on the back and have a true launch but I'm afraid the car will twist with no frame connecters or added support. Everything is in sound condition expect for the back frame rails which are a little scary at the ends only. Anyone have experience on this? Should I add some support to the car before attempting slicks.
