I'm running the BFG drag radials now, and i'm not to happy with them. I've got the 235/60/15's. With stock size, generic radials, my car ran 2.0 60 ft times. That was when the car was completely stock. After a few minor bolt ons--exhaust/chip/cold air kit etc. I went to the track with the BFG's and proceded to get some 2.1 60 ft's. Granted, I was trying to leave the line with boost, but it was only 2 lbs.
I know the 235's are small, but my buddy bought some of the 275's for his and he had to get spacers for it. I guess it's not a big deal, but it also seems like there is a lot of tire hanging over the rim with the 275's. Started looking up the Nitto's today, and found that the only size I could really run would be the 275's. Are they the same width as the BFG's?
