I took a long time figuring out the offsets for these wheels, and I'm really happy with how it turned out. You CAN fit this combo on the car without back-halving it. As long as you're not squeamish and you have some tools/experience. They won't just bolt right in, but the modification is pretty minor (and most of if it something you've likely already done if you have really wide rears (I had 315s for years, on custom 16x10 GTA wheels).

Front: 18x9 with Cooper Zeon RS3 255-40/18s
Rear: 19x11 with Cooper Zeon RS3 325-30/19s

Both sides require removing the bump stops and some BFH/huge drift punch work to increase the radius in the front inside part of the wheel well. On the Driver's side, you'll have to actually modify the spring pocket housing, as the ribs stick out so far (This isn't the case on the Pass side).


This made over an inch difference in inner fender to tire clearance. I also recommend modifying the lower part as it's closer than I'd like still. It's fine as long as the suspension isn't full extended.

This is a Photoshop-original-real new wheels comparison. I wasn't too far off!

Looks good, I actually had a set of CF5Vs from my 5th gen lying around, 19x11 rear with 325/30r19s (4th gen width rear axle) and the went right on, but no drivetrain in the car so its sitting pretty high, and the diameter of the tires is pretty tall. Fronts are 19x10s with 285/35r19s, working on that fitment via C5 brakes and possibly 1LE hubs. They are currently sitting on there with a little over 1/2 pf spacer, which is where a 1LE hub and C5 rotor should end up. Will probably go to a 275/30 front and 305/30 rear to get the diameter down a bit and keep the fronts in the fender.

Thanks man, there is one spot that rubs occasionally on the driver's side rear that needs to be bumped a few more times. It has settled down a little since the pictures, too, as that was right after it came off the jack. That should be a cool setup ... the rears will fit, it's just not plug and play.

Oh, mine went right on in the rear because I was already clearanced for my 17x11s with 315s. basic same mod as you, removed bumpstop bracket, and a small section of the frame right above that stuck out closer to the tire, replaced with flat plate. My 9" was already 1.25" wider than a standard thirdgen rear, ordered it that way from Moser, and added LS1 rear brakes. Also running the same 325/30R19 coopers as you, it is the 285/35r19s up front that will likely give me issues with the 19x10s, I am thinking a 265/35r19 to get the diameter and width down a little bit.

Oh gotcha, got pics of that? Sounds rad.

The Coopers seem decent so far, especially for how inexpensive they are for a tire that size. The 325s lay down some killer slabs, too
