Call CCW and ask. They'd be able to set you up good, as I assume you choosing the offset means you'll be ordering new. They've made at least a few sets of wheels for these cars so they'll know what you want.

i had called them to get a quote on pricing ect. and they said i needed to tell them the offset i wanted. they were kind of rude actually, not only that spending 2900 for a set of new wheels to get them and them be wrong based off of someones opinion that it should be flush would suck lol im sure someone on here has a set or has a set of wheels that are flush. i appreciate you responding though

What size wheels are we talking about here? Offset is a measure of distance from the center line of a wheel. A 50mm positive offset on a 9" wheel (center line of the wheel is 4" or 4.5" depending on how you take the measurement) will pull the wheel in closer (inward and away from the fender lip).

You're not going to get 4.5" of lip in the back with a stock width axle at most you'll get 2 maybe 3. 45mm offset is the least positive offset that will fit. A 12" wheel with 335's is going to be a problem also. You'll have rubbing issue, there are people who run them, but they've usually mini tubbed or pulled out the fenders

If my math is right a 38mm will get you to the fender in the front.

positive offset. To get the 1" to 1.5", you'd need to have your axle housing cut, narrowed on both sides, and welded back together, and new axles made.

Lee is absolutely right. Look at the pic below. Ive done the math and the outer edge of my rear wheels sits (give or take a mm) exactly where a 11" wide wheel with a 45mm offset would. I wouldnt go any wider than a 315 tire simply because anything wider would hit the quarters on big bumps. If you absolutely have to have a 335 tire, bump the offset up to 50 or 52mm

My fronts are 38mm but only 8.5" wide... So imagine them sticking out 1.25" out further and they'll be damn-near flush without sticking past the fender
