Looking into getting some enkei rims for my car, and I'm trying to figure out what would be the best fitment since they come in 18x8.5, and 18x9.5, with +35 and +45 offsets. Looking for a more flush, almost track fitment setup. It is on stock suspension as of now but might change in the future since I'm consider taking it to track days. Also what tire size would be best for max grip? Thanks!

For track fitment you want to run 265/35r18's; that size will be exactly the same as stock for the speedometer. For that wide of a tire, you would have to run a 18x9.5, but if you get too aggressive on the offset then you'll rub. With a 9.5, I would say a +30 offset +/- 5. But it might look stupid until you get coilovers. I think the nt03 18x9.5 +27 would fit perfect with 265/35. Also, konig's are made similarly to enkei's and have many lightweight 18x.9.5 +25/35 options.
I have 18x9.5 +15 rpf1 and it's too aggressive. I have no wheel gap at all and it's flush, but I run a 235/40 and can't go any wider or it'll rub. I'm running on natural camber, -2.5F & -3R which doesn't look too bad, but it's a little too much camber for me and I can't change it or it'll rub.
I test fit some 18x9.5 +30 regamasters on 255/35 and it was tucked. So the goal is to run those wheels with a 265/35 with -1.5 or -2 camber all round and I think it would be pretty close to flush.

Are you planning on rolling the fenders? Do you want to keep the stock alignment spec (or something close)?

It doesn't sound like you want to ruin your car, so I'd suggest some sort of "OEM+" fitment.

9" width and about a 40 offset or (better yet) 9.5+45 should work well and look agressive.

Either will push the wheel face about 0.75" outboard as compared to stock. You *might* need to do some alignment tricks or rolling to clear the rear fender lips.

I do not suggest rolling your fenders if you plan to use the car in very wet or salty road conditions.

The issue with going more agressive than the above wheel spec suggestions is that it will look like a rollerskate at stock height, and you'll rub somewhere. You will also affect the scrub radius by straying too far from the stock offset of +45.

You would use a 245mm or 255mm tire with the 9" suggestion.

Or a 255 or 265mm tire with a 9.5

The 9.5 +45 is the better of the two.

@BROlando I'm currently on stock suspension, but I plan on getting BC coilovers first to lower the ride height by about 1.5". I would like to get some Forgestar F14 in either 18x8.5 +35 or 18x9 +35. Which do you recommend to get a flush fitment? I don't want to rub, but I also don't want to roll my fenders.

Depends entirely on what size tire you go with, and how much camber you wanna run. You could get "anything" to "fit" with enough work.


Here's everything 18x8.5" +35mm "with zero fender work", on various tire sizes.

Here's 2 samples of 18x9" +35mm, with zero fender work.

fwiw, an 8.5 +35 and a 9.5 +45 will sit similarly on the outboard side. it also depends on what part you want to appear visually flush, the lip of the wheel or the sidewall of the tire. with the fitments stated the lip of the wheel will be a hair inboard but you can run a wider tire and you can make the tire appear flush.

*that's to say you could run a 'square' sidewall and look pretty flush, meaning without stretching or ballooning. nice vertical sidewall I think would generally be a 245 ish on an 8.5 and a 265 on a 9.5 ...

I would be willing to wager 245 on 8.5 +30 and/or 265 on 9.5 +40 is right at the outer limits for aggressive driving and suspension loading without rubbing on untouched fenders. with a grain of salt, based on my limited experience

what is the offset of the factory 8.5" aspecs?

I believe it is +45, like the stock wheels.
