I know Jim, but having very light cars with no way to improve the rear end set up...just maybe a little more weight somewhere would help...I believe what I have now with the Hoosier and rims is by far the best set up, but willing to experiment a little. Although my summer tire compound has netted a better 60' than the drag radials, but they aren't consistant. I haven't made up my mind yet, but I appreciate the advise.
