One other thing I should mention- Those little G70-14's have substantially more traction than any of the street radials! Take a look at this pic, you can see the side walls wrinkling on the launch!
Those big 275/60's don't even come close! The Lemans will smoke them for as long as I stay on the gas! The Polyglas will spin too, but they eventually hook up and go.
I also found another pic, this time with 275/50/15 BFG DRAG Radials on the back. They're really pushing it on the 15X7 Rally rims. Too much sidewall bulge.
Robz, yes those are still the 225/70/14's on the front in that shot. I'd have prefered to put on 235/60/15's but they're mounted on the T-37 right now.
