Size, offset?

8.75:

Staggered so you can see the different concavity:

So would 18x9.75J +20et w/ 235/40 All around be rubbing? Just installed my BC BR Type Coilovers yesterday. Didn't mess with the height, just installed them the way they came out of the box (which is low already w/ about 1-1.5" more maxout). I want the "slammed" look, with the most concavity on the wheels I can get, but if I can avoid rubbing that would be GREAT!

9.75 +20mm up front is really pushing it (perhaps quite literally)!!!

I think even if you max out on camber, you will poke like a mofo.

Ok so in this case, would an 8.75 be more ideal for the front and 9.75 for the rear? Also would an 8.75 +20 be more concave than an 8.75 +35?

whitefrs · 03-31-2013, 09:17 AM

I would do
18x8.75 35 front
18x9.75 20 rear

Now remember.. I want the most concavity I can get. Is this the best set up for what I'm looking for?

Vten · 03-31-2013, 09:28 AM

Has anyone tried this yet:

18x8.75 et35
18x9.75 et35

A friend offer me 225/40/18 F and 255/35/18 R Michelin pilot sports tires that I can't pass.
Would it rub a lot with Umpadupa height setting ?

They don't offer the 9.75 in +35, only +20

Vten · 03-31-2013, 11:02 AM

Oops pardon my newbieness

How about :
18x8.75 et20
18x9.75 et20

How much poke would they be ?

on stock suspension without any camber set:

18x8.75 et 20 will poke out about 20mm in the front
18x9.75 et 20 will poke out about 30mm in the rear

If you're not planning any overfender/widebody kit you should go for 18x8.75 et35 square (when lowering the car/put some camber to it) or even a 18x8.25 et 35 if you stay on stock suspension and do not like the wheels to poke out a bit

Also to state one point regarding the ET of wheels

Less ET does NOT necessary mean more concavity. There are some wheel design that this is true, but in case of the XXR527 this is not.
Some wheels simply keep their concavity but the center of the wheel gets more "space"

compare those two pictures below.
White seems to be a 8.75 with ET 20 (just the front wheel, the rear one is a 9.75)
Black is a 8.75 ET 35

Now look at the center of the wheel, where the lugnuts go. You can see that the white one is far "deeper" than the black one.

As far as I'm aware, the XXR concavity does only change by the wide of the wheel itself, not by its ET.

So would

18x8.75 35 front
18x9.75 20 rear

be a good set up? or would a better set up be a front of 18x8.75 20?

Wonderbar · 03-31-2013, 12:56 PM

I'm pretty set on these as my daily wheels, powdercoated white or the gold from xxr.

17x8.25 +35 front
18x8.75 +33 rear

Anyone have weights of these?
