Roller perches man, 6cyl shocks, and 90/10's call it a day. Oh yeah, I don't know how you have gone as fast as you have get some TRACTION BARS !!washMO66 said:Thnink that sam size would fit on a 66 coupe w/ 15" & 4.5" bs? Or am I relegated to the 255/50/16?
I need some street traction, I'm tured of getting spanked in the first 60'.

Thanks! Great pictures! They sure don't look like they are 28" diameter tires so 275 does equate to a 28" tall tire right? I guess they are hanging so far down they look smaller compared to the wheel opening. Did you notice the shiney spot on the rear fender well in your picture? Was that from your pervious tires? Have you placed your jack to one side of the rear end and jacked up the car to see it it will hit the bump stop first before the wheel well to simulate a hard launch?
the 275-50's are 26" tall. the 275-60's are 28" tall. the car is jacked up by the rear end, so that is the ride height. the shiny spot is just the camera flash.thehueypilot said:Thanks!

thehueypilot said:Attached is a hard launch view that shows how far the rear tire moves into the wheel well. I have 26" tires now and they do not rub, but would like to go to 28". It looks like with a better tire another inch will pull the front wheels off the ground and improve my 60' time.

By the picture I bet that you spin the first few feet and then hook up pretty good. Some stiff springs will solve that. As the car squats, you have no traction. Not until the cars suspension bottoms out, and plants the wieght, does it grip. Hell, I bet you get that rear to stop squatting and the front will come of the ground.

thehueypilot said:I know what you mean because I lose fuel out the back on each run as well and I thought about putting some kind of check valve in it. Why would roller perches keep the front end from coming up? I would think it would allow the front end to raise quicker which would than pull the tires off the ground. I am using the "grab-a-track" leaf springs which I thought were heavy duty?
