I am looking for a 18 inch wheel setup for my 1LE has anyone looked into the idea or know of anyone or company that has rims that fit the 6 piston.brake system. Any help would be great thank in advance.

There are 18 inch wheels that will fit over the brakes. The problem is inner clearance. Im assuming you are wanting to do something wide? If so, you will be limited.

+1 on the 18" wheels fitting over the brakes. Tire Rack will tell you exactly what fits in each width. I'm running 18" snow tires on all four corners.

I'm sure someone has a brake template for these. They should fit in the barrel of most 18" wheels but certainly not all. I believe any of the Apex ARC-8 or EC-7 18" wheels will clear the caliper but there's not much room. I ran them on a different car with 380mm front brakes and clearance was only 2-3mm. Prepare to cosmetically damage the calipers and wheel barrels in doing so because tiny pebbles and other road debris will get caught between the two and scratch both up. There's no getting around it.

Nah, no issue with track debris scoring up the calipers. I ran “18 Arc 8 this past year, no cosmetic damage. Lots of track miles.

So what do you guys suggests for 18' winter tires? After some research I found that no 18's radius perfectly matching that from the original 305/30/R20. I wonder how much tolerance can the car handle before ABS or traction control steps in? Tire rack suggests 275/40/R18 and 285/40/R18 for front/rear.

No issue with TC or ESP with smaller OD tires. ABS, ESP, even PTM works perfectly with a 285/35 18, or about 7% smaller OD on track....so street use is certainly no problem. Only issue is the Speedo will read high.

Any concern with clearance for the stock SS Brembo calipers? Want to use the same wheels for fronts & rears. Thx again.

18" APEX
Plenty of claipier clearance. 1/2" spacer and some mild clearancing needed on the strut.

So you're running this setup on the track? With the spacers?
