The only reason I say that is the slick is a softer sidewall and will deflect and rub when making turns either when loading/unloading, during the turnaround at the end of the track etc. I have BFG radials for street tires with 1/2 clearance to the spring and never leave a scuff, But my slicks which are ET Drags you can faintly see a few scuffs on the inside sidewall. They are dimentionally the exact same size tire but one rubs and the other doesn't. IMO you don't need more clearance with a slick verses a street tire. I've run plenty of slicks less than 1/4" from round tubing and they never touch except maybe a little during tire shake.

I have less clearance than the QTPs and very minimal rubbing now. Anything bias ply is going to not like going around corners with minimal clearance I think...

I remove mine for better leaf separation and notice that it will allow the axle to move more side to side in turns. Just don't go so fast in the corners. Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
