I would say 1/2" for street tire and maybe 3/4" or a hair more for a slick. 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 think you need a little more clearance when you remove the clamps behind the axle that hold the leafs together. 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.

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.
