These are 24.5/8/13 MT ET Drag slicks mounted on 13x7 panasport wheel, I just want you guy opinion on the clearance of the slicks since this is my first set of slicks( i bought these used).

Seller advertise them as one pass down the track, the slicks are air up to about 20 psi so i dont think they will grow any bigger? Im worried they will rub the fender when i brake after the 1/4 mile.

i did get on the car and bounce up and down to duplicate too see if it would hit the fender. I rolled the fender until the fender is not touching the tire when im bouncing it up and down with me in the engine bay lol, what do you guy think? will i have problem.

suspension is Koni yellow with neuspeed race spring so ot the stiffer thing out there

 

At speed the tire will effectively get narrower and taller, so just ballooning the tire out with a ton of air pressure won't get you what you want to look for. Since you have Koni yellows, why not just raise the from perch another notch? That I'm sure would get you plenty of clearance. Just brake softly and you should be ok. Look for rubbing on the tire and the fender after each pass.
