The biggest problem is getting traction off the line. I stopped on a bridge that was concrete a while back ( where we use to race in my younger day's) and did get a really good launch, didn't hardly break loose at all. When I took the guy for a ride yesterday I had it in 1st running about 20 MPH and just floored it, it broke loose, got just a little sideway's and shifted to 2nd then when it quit spinning I let off it. He had a bad case of the big eyes, smelled like burning rubber in the car for a while.
