Another fitment question. From different sources I’ve seen that this square fitment is possible, but front camber is a must. I’d pull the camber pins for now and grab camber plates later. I’d run 275/35/18 falken tires.

Will I need any spacers, like 5mm to clear struts? Is this feasible? Looking at more used wheels.

Will this be for track use (i.e. you want the extra width for better sidewall support) or for street use? For street use, it probably make sense to run 18x10 as 275 can look stretched with some street tires and be less inconvenient for clearance. A benefit of 10.5 is if you plan on running 285/30/18 or 295/30/18 up front in the future.

Something you can do is measure the distance to strut from your current wheel setup and calculate the difference there, as well as where the closest point of contact is (i.e. are you reducing diameter?).

Lastly, I am not sure pulling camber pins will work in the same way as camber plates to help with clearance. Typically, adjusting camber at the arms can increase track width by bringing the bottom of the wheel out (and thereby increasing camber) whereas camber plates move the top of the strut inward (increasing clearance to fender).

This is not pertinent at all to your situation but with Continental ECF 275/35/18 (wide shoulders), 18x10.5 ET22 RI-A, and Nitron R1 (5" spring with helper), I needed a 5mm to clear the strut. This is not as bad of an issue with tires less wide in shoulder since I was rubbing the tire sidewall. I am not sure how OEM EDC compares.

This guy F4rmost ran 18x10.5 ET22 with 295/30 square on EDC struts so you might wanna reach out to him: https://www.m3post.com/forums/showpo...postcount=1157

This is for track use, I’ll be getting falken RT615k’s with them from the seller. My 359M wheels w/ps4s are for the street. I’d love to put wider tires later on for this set so 10.5 gives me room. Not going with 18x10 as I can get these wheels for a great deal as is. The stretch here may help me with clearance.

You wont need to pull the pins to get them to fit. These are 275/35R-18 Bridgestone Potenza Sports on 18x10.5 et22 no spacers and stock EDC struts w/swift springs.

I got them from a member on here that ran them with ohlins r&t with no issues also. They will not fit on ST Coilovers or anything without "bee hive" springs without spacers.

That looks great, I’m sold on this fitment. Can’t wait to grab them this weekend. Thanks for the insight!

Thanks for the shout out bipp!

I was running 3mm front spacers and vorshlag camber plates with about 3 degrees of front camber.

I am on coils now and scheduled for an alignment tomorrow!

What coils did you go with?

Yellowspeed premium competition with true rear coilovers.

They are a taiwanese coilover, but will hold me over as my edc was pretty much done. They are a control coilover for a few racing series and seem great on the street so far. I am interested in seeing what they will do on the track.

And no issues with the inside of the fronts rubbing with the 10.5 +22? Or is that why you had the 3mm spacer?

Nice! I grabbed the wheels and am running on stock EDC with no spacers. Checking your post was helpful. Lowering it would help with fitment for sure, but I have no rubbing.

I had the 3mm spacers and vorshlag camber plates. I got the spacers because I was rubbing a little bit on the lower spring perch. I think that was because I was running a 295 PS4S and they have a pretty square sidewall.

I am running a 5mm spacer now with the camber plates that came with the coilovers. This time I needed a little bit more spacer to clear the lock ring on the coilover.

Awesome! I am glad I could help someone! Great choice of wheels, they look fantastic. Lowering will help, but one thing at a time!
