Switching to a drag setup from a street setup Switching from 285/35 Michelin pilots in the front and 315 35 17" BFG drag radials in the rear to the CCW drag setup(ET streets and skinnies). Assuming the old 60' was 1.70 and the new 60' is 1.50, how much ET do I stand to cut off? I have heard for every .2 you cut in the 60' you can remove .4 in the 1/4. How much of an ET reduction should I expect with this package that saves 75lbs of unsprung weight?

Re: Switching to a drag setup from a street setup Reading on the supra forum that adding skinnies up front a few have seen 2 tenths in the 1/4. Any F-y bodies with experience?

Re: Switching to a drag setup from a street setup I lowered my ET by .05 with the skinnies. What really improved was my RT times. The car rolls out almost .1 quicker. My 60' changes my ET by 1.5 times either way. A .2 lower 60' will lower my et by .3 For the point races this year I'm swithching from 315 BFG's to 28-10.5-15 ET Streets. However I'm also swithching from a M6 to a turbo 400 so I won't be able to tell the real difference in the tires. Once I get the car dialed in with the ET streets and auto I plan to hit a test and tune session to see the difference with Drag radials. I do have a few special races this year where they require radial tires. I'll swithch back to radials for those events.
