I have 18 x 9/35 offset on the rear. That offset is very close to flush and will look good. I think the 18 x 8.5/48 offset in front will also be close to flush and should match the rears above pretty well. The offsets on the other setup you list sounds too aggressive. Those wheels will stick out for sure.

 

^^^
So the 35 and 48 offsets on those wheels are noticeably closer to being flush than the stock wheels?

 

If you need to stretch the tires to get clearance, then you can't run 265 or 275, more like 245 or 255. I also don't understand how you can need to have stretched tires for an aggressive fitment but keep your stockers on now.

 

What does he mean by "stretch" anyways?

 

If you're concerned about caliper clearance and rubbing issues let's analyze the specs. 18x8 +45mm front and 18X8.5 +50mm rear. Javier used hubcentric adapters +12mm(1/2 inch) front and 17mm(3/4 inch) rear. So by getting 18X8.5 +45mm front and 18X9(or18X9.5) +50mm this set up will give you a flushed wheels with no problem with clearance and rubbing. In short, you're gonna use same offset as oem but wider 12mm(1/2 in) front and 1/2 - 1 inch rear. Did I nail this one Javier?

 

stretching means putting a narrower tire on the rim, in your case for the rear you may want to run a 255/35-18.
as for the offsets that is pretty aggressive and you would most likely have to stretch the tire and maybe roll your fender, nothing horrible. it can be done, i have seen 350z fittment rims on our car so anything is possible.

 

But these aren't the OEM offsets... The front on these wheels is +48 (you're saying OEM is +45, I think), and the rear is +35. So are you saying that still wouldn't cause any problem?


OK, well I think I see what he meant now based on kilo's explanation... So I would need to stretch the stock tires (or tires of similar size) inorder for this fitment to work, right?

 

Yes, but you can get flush without stretching and running <30 offsets, so why do you want to? The +48f with 235 and the +35r with 265 should look and work fine.

BTW, are you going with the FS-01s?

 

So you think the +48 and +35 will be relatively flush? At least moreso than stock? That would be good... because I definitely want to run at least 265s in the rear. It's not really that I want to run the <30 offsets... these were just the two possibilities with the wheels that he suggested. I wasn't really sure which would be better.

And yes, I decided to get the FS-01's. In sapphire black, heh.

 

I don't think the stock 255s will be flush but when you get the 265/275s they should be.

 

Well what about the face of the wheel? Would that be flush?

 

Absolutely. It should look pretty good and very close to flush. As for the tire size. I reused the stock 255/40s on my 18 x 9 rears and they fit very well. The sidewalls are flat and parallel to the face of the wheel. I think 265 width would work well too. 275 with might get a little bulgy looking on a 9" wheel. 235's on the front should look good, 245's might even be ok.

 

This is incorrect. Doing what you said (18 x 8.5/45 and 18 x 9/50) will only move the face of the wheel out 1/4" and would be closer but nowhere near flush. Remember offset is measured from the center of the wheel and using the same offset only pushes the wheel out by half of the 1/2" extra width. As for caliper clearance, that is more dependent on the design of the wheel and not so much the offset.

 

Do the math.

Front: +48 pulls the wheel in 3mm further from the fender. This is offset by the fact that the wheel is a little wider by .5", which effectively pushes the face of the wheel .25" closer to the fender. In short, it all works out to the face of the wheel being 3.35mm or .132" closer to the fender, which won't be noticeable in and of itself.

Rear: +35 pushes the wheel out by 15mm in addition to the added .5" in width of the new wheel (which again pushes the face of the wheel out by .25".) Therefore, the wheel is .591" + .25"= .841" closer to being flush with the fender. This will probably be noticeable especially if you end up with 265's.

The rear offset looks good. The front is not going to do a lot for you. You're going to have to decide if the looks of the wheel (compared to any alternatives you might have in mind) outweighs another brand/style of wheel that might give you a little better result in terms of the wheel being flush.

Buying wheels is almost always a lesson in compromise. Love the looks but not tpms compatible. Offsets are great but I want it narrower/wider. Look great but they weigh a ton, ETC.

My wheels are tpms compatible, very lightweight, and from a great manufacturer. They were actually my 3rd choice in terms of looks though.

 

Actually, after reading, I agree with what al503 just said. The 48 offset on the front won't look flush but it will be slightly better than stock. I think about a 40 offset in front would make it look pretty close to flush and match the rear well too. If you can't get this wheel with a lower offset you may want to think about spacers for the front, which would also help add caliper clearance if that is an issue. The 35 offset for the rear is soild though don't go higher or lower.
