Dear Jeff,badrod said:Looks like the best we're going to do with the stock rims & stock exhaust (actually modified SE slip on's) is 10.5's. Tried a lot of different things but we're having a tough time with traction. We'll we back at it in a couple of weeks with new rims, softer tires and a new exhaust. I'm posting a movie of the 10.519 run in the movie thread. Jeff
