69 Firebird - Wheel Setup

[ModernMuseum]

I've decided to go ahead and order the tires and do a mock-up fitment after performance numerous "in-air" measurements. I've decided on these, as they fit my budget and I believe are a good cross between street and track. Most of the 315+ tires seems like track-ish tires anyway unless you want to pay $450/ea. for the Michelin PS2's, which is ridiculous.

Anyway, tirerack has both a 245/35/1 and 245/40/18 for the front. Will the 35 look too thin up front? It looks like a lot of people have been running the 40 tread wall.

For the rear's, after searching numerous boards, I'm going to go with a 315/30/18.

The wheels I plan on going with a are 8" fronts and 11" rears - Boze Pro Touring 18". After getting the tires here, I'll have to figure out the appropriate backspacing.

It's important to not make a mistake when ordering custom made wheels, so based on above here's what I'd do:
- measure your wheelhouse @ 10,12 and 2'oclock
- measure the width of your rear end flange to flange
- go here for reference: http://www.1010tires.com/tiresizecalculator.asp
- go to Kore3's website - or any other's that sells the brake kit you are considering - and print out the caliper fittment template for reference. This way when you do any upgrades you know the brake of choice will fit!
- Call Frank w those measurements and he'll get you the proper Bspace for your wheels

Another thing to consider is that you're doing the tubs so you should be good on 315's. If your rear end is too wide for whatever reason, you can usually buy a 1/4" - 5/8" with a fender lip roller.

Last thing - post pics when you get them!
