Has anyone found a few that work? I know it's been hit or miss, and trying to put a list together for everyone to see if they wanted to do 18 in to fit 305/35R18 tires.
 
Do you really think 18" will clear the brakes ? Stock 19" are very, very tight in the front.

They wouldn't clear this dent........

Oof, maybe the rears then? the goal is to fit some 18" radials

Looking for rims and winter tires for myCT4 BW, any help would be appreciated.
 
Look up Apex wheels. I know for a fact that they have 18" wheels that'll clear Corvette and ZL1 brake systems. Should clear ours.
 
Has anyone found other wheels than Apex that fit and dont require spacers? Maybe even 9.5" front and 10" rear fot CT4v BW.

Do any of the OZ racing offerings fit?

The fronts could probably fit with a good amount of camber, I was planning to take extentive measurements and have some custom wheels made but instead I just confirmed my allocation positions for a 5BW and will be running 200TW tires on the stock wheels.
 
Hit up Klotz Bro Racing. Nick knows a great deal about CT4-V and 5-V BW fitment. A lot of us has moved onto 19" BC Forged wheels. Most are running 295-305 in the rear and 275 up front with no rubbing.
 
I wonder if these would fit for a square winter tire setup on the CT4:

BRAVADO Part#SizePCDOffset (mm)FinishCenter BoreConstructionNet Weight (lb)
TB8952030518X95X12030MATTE BLACK67.11-Piece25

Not lightweight by any means. Is 67.1 vs 69.9 a small enough difference to not require a centering ring?

Edit - nevermind, they dont look like they would clear the calipers
 
I'm looking for winter rims and at Discount Tire was told that these would work.
Any thoughts?

Aerolarri makes 18's for the 4BW. They are custom so no spacers.

The only other ones I've found are Volk TE37 saga sl. Stock widths and pretty close offsets.

Has anyone tried stock ATS-V wheels? I would imagine they should fit for a set of winter wheels?
 
I had this company make me a set of custom wheels for my M3, there prices were very very good. I already asked about making some to my specs for the 4BW but haven't went further because I didn't take the time to measure clearance on the lift and it would be much easier to just replicate a proven setup but I can't seem to find anyone who put the effort into fitting larger 18inch wheels on the 4BW. Tire selection also needs to be checked depending on what you want to do with the car.

 
I keep getting them saying that an 18x9.5 35 offset would work and 255x35x18 tires all around. This is for winter. Any thought?
 
I went with some BC Forged HCA 165s
