Chances are...from that pic, that the OEM caps will fit that wheel.
My reasoning is this. The AAARim replica appears to have the same "chrome" centercap that comes with other replicas (WheelExchange, EdgeRacing)....and I doubt that there's any difference in those caps. If that's the case, then the OEM caps will fit the AAArim replica.
A few of the replicas are TT ALMS replicas, but the difference is very very slight. Nothing wrong with that though, as they still LOOK pretty darn close to RS4 replicas.
So besides that, offset seems to be the only other tangible difference. Achtuning I believe is the only place to offer it in ET35, which is the "accepted" offset around here. Most others are ET30.
They're ALL heavy (at least 27lbs), I don't care what one place might quote you about their replica. Achtuning = 27lbs. WheelExchange = 28lbs (though they'd like to claim 25-26lbs). Yeah, they love to fudge those wheel weights.
As far as strength goes.....well, like I said, they're all heavy. A lot of people use the analogy that heavy = strong. Sure....take that FWIW. I don't think we can accurately say that one replica is stronger than the others or one is significantly softer.....until there are MANY MANY sets out there on the road. Even then, it'll take a pattern of lots of bent wheels before you can convice me that "so-and-so's" replica is soft. And it goes the other way, just because a certain replica has never been reported to have bent, doesn't mean that it's automatically the strongest replica out there. ALL wheels will bend if you hit them hard enough.
Anyways, hope this helps. This has been covered thoroughly in the archives, so you could search if you want more info. Good luck
I'm running 225/40 18's ET30 and do get some rubbing when I hit a large hump in the road. You'd probably be ok with ET33, but it really just depends on your suspension set-up and the tire size. Good luck
