Just wondering what the concensus is on what works best with a heavy car and a 4spd at the track? My gtx is 3925lbs without my butt in the seat and have ran my best 60ft times with a bias ply tire m/t et streets. I have run e/t radials the last couple of times to the track and having a hard time getting a good 60ft without spinning the tires. I am far from an expert at the track and just like to play but would like to get the best possible traction when I do go out. Best 60 with the bias plys is 1.760 and 2.001 with the radials. Any tips on what would work best with my setup?
