Default Track wheel fitment

I feel like a nubie asking this but i couldnt find it in the help bar... I think im gonna sell my strasse wheels and go to even smaller mono block. Im sick of bending wheels in the north east and 3pcs wheels do not hold up to my abuse mixed with our road conditions. Will I be safe running a 18x9.5 wheel all the way around the car with with a 38 to 45 mm offset if I have 275/35/18 on the car?
Thinking either enkei rpf1 or volk te37sl with toyo RA1 tires....

ERDoc74 ran 275/35R18s on 18x9.5 +40 wheels without much issue. I think 18x9.5+45 all around would be better. I personally mounted my 19x9.0 +55 stock ISF wheels on the front with a 10mm spacer for about 15 minutes to check the clearance of the 275/30R19 Michelin PSS tires in front. While I didn't do more than crank the wheel and drive forward and backwards a little bit on uneven ground, I didn't experience any rubbing...but that is at stock height.

Long story short, I think going square with 18x9.5+45 and 275/35R18 you will be golden.

Also, have you considered BC Forged wheels? You could run gorgeous 18x9.5 (+45) front 18x11 (+60) rear monoblock forged and very light weight for a little over 3k. I've considered this setup with 275/35R18 and 295/35R18 Nitto NT05s.

I'm running PF01's 18x9.5 +45 offset with Hoosier 285/30/R18 R6's for track use and the clearances are very tight. Running a little low on tire pressure (22 PSI) will rub in the rear on the inside. I have no intentions to run that low but just to give you an idea on how close it is. You're correct, for everyday use 275 is best

18x9.5 +45 RPF1s will not clear our brakes (due to offset). Sucks because I love the way they look.

Im not super worried about the height issues, i can raise or lower the car but i want to make sure the rim i buy clears the brake caliper. SSR has some new flowform wheels out in this size too which would look good

Still wishing for an 18 or 19 x 10.5 in a +50 (or so) to run a 295 without squeezing. Getting a set of 2012 wheels powder coated this week (original job looks like someone did it at home) and will be on the 275 and 245 PSS set by the end of the week.

The SSRs look interesting, but all the wide wheels (10.5") have too low an offset to work well on the F.

forgestar , you can choose widths and offsets and run pretty cheap. could get up to 19x12 +55 offset for 1600 shipped. also it uses the same casting process as the enkei lightweight wheels..might not be strong but its light for what it is.

Just ran into this problem trying to mount mine...hoping a small (5-10mm) spacer will get it past the caliper.

Lobux, curious to get your take on twice powder coating wheels. I've always read that you should never powder coat forged wheels (seems this is the consensus on most of the threads I've read). Some say as long as you're baking it at sub 400F you're fine, other say it's the method of stripping and cleaning the wheels that is the issue, and not the baking part... either way have no idea clue. But I have a set of MY11 wheels that have been powdercoated once already (one wheel actually powdered coated a 2nd time too), but the shop that did it did a horrible job and not soon after the powdercoat began to crack on all wheels. I want to repowdercoat these wheels at a more reputable shop, but concerned about the potential issues this may cause down the line, especially if 1 of the wheels will be on its third job. Because this shop seemed to have been less than reputable who knows what they did and didn't do right during the first job.

Curious to get your thoughts on this, and any insights you may have with this process.

The last time I had wheels done, they were painted, not powdercoated. There are a couple of companies who powdercoat all their wheels from the factory, so it is possible to do it and not lose structural integrity. How many times it can be done before the aluminum gets brittle? No idea. Am I really worried about it? No, not really. Any powdercoating professional should know by now how to do this right and not risk a liability lawsuit for overcooking a set of wheels.
