Thinking about Prostars, size ideas?

[79loserbluebu]

Will be used on track, looking to improve my brutal 60'. Found a set of prostars powdercoated gloss black for $500. Want to check with the experts first. Don't want a tire sticking past the fender (stock height)

Fronts 15x4 1.75bs
Rears 15x8 3.25bs

Any thoughts on this setup? Tire size? I think a drag radial should be plenty, car weighs 3450 and has 378rwhp. Boxed lowers tubular uppers 3.73s, truetrac, moser axles, 8.5 rear.

Thanks

I believe you need more backspacing on the rear otherwise they will stick out some, most people go with 4 inches of backspacing...and as for popular tire size, I know a lot of people run 275/60/15.

Thanks for the response. I looked into it a little more and you're right, the majority of people use 4" bs on a 15x8. Oh well back to the drawing board.

For anyone in the Chicagoland/NW Indiana area here's the listing, love the way the wheels look
