C5 Corvette Wheels on 335xi

tb30570 · 10-24-2014, 07:56 PM

I have (2) Z214-C71 275/35-18's on 18x9.5 C5 wheels with a 65mm offset that I run on the back of my C5 for autox. I'm looking at getting some Z214-C71 tires for the front on 17x8.5 wheels with a 58mm offset.

I'd like to run the same wheels and tires on my 335xi for autox.

I did a fit-up on the rear with the 275/35-18's and they would fit with a 5/8" spacer. A 1.25" spacer would keep the center line close to stock but wheels would extend pas the fender pretty far. I think a 1" spacer would be best.

The front looks more tricky. OEM wheels/tires are pretty much flush with the fenders. There is about 9/16" of clearance between the strut and the tire. The max back spacing is probably around 150mm. A 16mm spacer should make just enough clearance for 17x8.5 wheels with a 58mm offset. An 18mm spacer would be a safer choice for clearance. With an 18mm spacer and 17x8.5 wheels with a 58mm offset, the front spacing would be farther out than OEM. I'm pretty worried about increasing the front spacing that much.

Who has mounted 8.5" wheels on the front of a 335xi? What offset did you use? What size tires did you run? 225/45-17 or 245/40-17?

I ordered 18mm spacers for the front and 1" spacers for the rear. That will make both the front and rear ~40mm offset. Im leaning towards the 245/40-17 in the front but nobody has any c71's in stock right now. More to come.

The rear spacers came in the mail yesterday. I did a fit up and it fits but the tire is pretty much flush with the outside of the fender. There is a lot of space on the inside. Im going to try a 12mm spacer instead so the chances of hitting a body panel is reduced.

Didn't know they were the same pattern. Would love to run some ZR-1 reps

Nice, makes sense camaro owners have been using BMW wheels in the past.

they aren't exactly the same...but close enough.

BMW - 5x120mm
GM RWD - 5x120.65mm (5x4.75")

The center hub is different. GM's is 70.3 and BMW is 72.56. If you are using ≥12mm spacer, you can space it out past the center hub so it doesn't matter. This could potentially result in vibrations at highway speeds for a daily driver from being slightly off center....but if you are just running for autox once in a while its no big deal.

I ended up buying new 18x8.5 C6 wheels for $100 each (free shipping) off ebay from "tirewheelblowout". I installed a used set of 245/40R18 Pirelli Pzero Rosso tires which have a 220 wear rating (meets 2015 SCCA street tire rules). I used the 12mm spacers up front and 25.4mm spacers in the rear. There is plenty of clearance all the way around.

They felt a lot lighter than the OEM's. I just weighed the OEM's and they are 53lb with 235/45R17 Nitto Motivo tires. The c6 wheels and tires only weigh 47lb.

Watch them carefully as bolt pattern is off. Not my taste. I've owned both bmw and Vette. Wheel looks don't work when swapping to me.
