Advice for all square set up for e90 xi.

Lshaw · 02-01-2010, 09:09 AM

Hey guys, im looking for new wheels.
-I currently have staggered 19/8.5 et 35 and 19/9.5 et 33 VMRV710's
-I'm thinking on going all square now because of understeer.

Im looking toward Forgestar F14 18/8.5, help me with offset!

What is the most aggressive offset i can run without running into problems. I would be getting 245/40/18 tires. Since i cannot overcome the fact that my rear will tucked in with the same front and rear offsets. I would like to know if i run 18/8.5 with 245/40/18 all around with different offsets will it be better than my current set up?

There will be a drop with kw v1's in the future as well.

Are you more interested in looks or performance?

mike-y · 02-01-2010, 09:58 AM

use et35 all around, but add a 10 or 15mm spacer on the rear. You might be able to get away with et30 or 32, but I'd measure, because you might rub up front with a 245 tire.

haha Both, i am eventually getting coilovers and i just want to be as flush as possible. F14 offsets can be custom made so can have any offset bascially.

How about something is between 30-35? I dont want to use spacers, i've had back experience with spacers and plus im all wheel drive, i always felt that spacers felt weird.

mike-y · 02-01-2010, 01:40 PM

the issue is that the front and rear would require different offsets to be flush. the fronts would probably be flush at et35, but the rears wouldn't. you'd need et25 or so (hence the 10mm spacer). you could get different offsets on the front and rear wheels, but then you'd lose the ability to rotate your tires.

what kind of problems have you had with spacers? Mine (10mm) seem to be just fine, but I'm rwd.

Some cheap ones tend to be "out of round" causing an "inbalanced" feel similar to if your wheels were out of balance from improper balancing of weights.

Ive had this happen to me once before. Not fan of spacers because of this, but I know there are sound products out there.

Exactly, ive had a few sets us spacers back when i had my csl's. It almost felt like my wheel was about to fall off. Id rather figure out offsets.

It's proven that the E9X M3 18" front wheel with the factory 245/40 fits on the front of the E90 with no rubbing, and it is ET29... With an xi you should have even more room.

Hmm, i understand i have 19/9.5 et 33 in the rear now even with a 275 tire. Its still tucked into the fender just a bit. When i go to a 18/8.5 245 tire i can see how much more tucked in it would be. My front is 19/8.5 et 35, its pretty close to being flush with the fender.

This sucks, haha. Any other suggestions out there?

Thats good news. I hear it all depends on the tire i choose as well. If i were to go 32 or below with offset, will the front be out further than my rear, or may appear to look that way. Also, as for rubbing, what if i were to drop it with kw v1s?

You can check with the OP in this thread--he has Eibachs and doesn't rub with 245/40's in the front. Not sure about kw's--guess it depends on how far you drop...

Sweet that gives me a good perspective. Thanks!

mike-y · 02-02-2010, 10:24 AM

keep in mind he rolled the fenders "to the max". so if you do that, you should be good to go.

For the M3 18's with stock tires, fronts don't require rolling...

OP wants 245s, as he said in the very first post. This requires the fenders to be "rolled to the max".

Stock M3 fronts are 245s.

mike-y · 02-02-2010, 11:56 AM

well, the first link you posted said the he rolled the fenders:

Quote:

1. Car specs: 2008 E90 328i ZSP, lowered on Eibach Pro-Kit Springs, all 4 fenders are rolled to the max, and aligned to factory specs.

tho maybe he didn't need to roll the front.

Lshaw · 02-02-2010, 08:59 PM

Perhaps im thinking of....going 18/8.5 with different front and rear offsets....may b even 19''.

My only concern was understeer, and a more aggressive look.

Mike01ci · 02-17-2010, 09:13 AM

I have 2 used 245/40/18s if you want to give them a try.... http://www.e90post.com/forums/showth...=245%2F40%2F18

Derek Zoolander · 02-17-2010, 10:34 AM

Do 18x9s with staggered offsets and 245s

flukey · 02-17-2010, 11:01 AM

I am lowered on KW V3 and have run the following square setups:

I run 19x8.5 +35 with 235/35/19 during summer and 18x8.5 +35 with 225/40/18 during winter.

I use 5mm spacer on all four corners too so my offest becomes +30. I've noticed slight rubbing in the front with my winter setup when making sharp turns quickly. It doesn't concern me very much though.

I didnt get rubbing with my summer setup.
