also, what strut bolt trick are you referring to? i knew there was a kit for the ///m's, but it won't work on the rest.

Damn. Rears wouldn't work even with a 235? That's sad, these wheels look killer on AW.

You can get a degree or so using pre-existing holes in the strut tower. I'm fuzzy on the details but my BMW tech said it's kosher. No kit or anything, it's all there from the factory.

putting a 235 on a 9.5" wheel is suicide... scary!

the strut tower mod is simply removing the factory guide pins, and does not require any bolt kit. if there is some other mod going on, be sure to get detail and post them. zpost would be glad to have more information.

also, you could use 4 front wheels on carefully selected tires. you would still need one helluva neg camber setting for the front though.

I guess it is...just thinking 255 wouldn't work. I'm hardly a stretch guy, I like the meaty 245/40 on my 18x8.5, just REALLY want those wheels to work. Oh well, but if stock M Coupe/Roady wheels will work on a non-M I didn't see these being that much more aggressive.

That strut tower mod sounds right, it's just the guide pins IIRC. Wish I was the mechanical expert but alas, no. Hell, we're still trying to code out TPMS on my '07.

Glad I found this thread.

Sub'd.

I need to find wheels ASAP.

Shamesless whoring, if anyone wants to buy some mint 5x112 OZ Ultraleggeras let me know.

Back to fitment!

Post in classifieds, that's what it's there for

[Jaguar_7777]

Well after a long month or so wait, the new 18in 313's finally arrived.

They fit great and are a huge improvement on the original elypical 202's i think, that are boxed up now for sale in Hong Kong...

.


Thanks for the help and advise to all from this thread!!!!

Just a few more days and the BMW Performance brake kit goes on as well.

[3002 tii]

I want 313's in 18x8.5 square real bad...

I'm not too picky, I just want 313s, 18 or 19s will do, no money for rims right now though

19x9 et48
19x9.5 et45

Yes with spacers. I runned 9x19 ET44 f/r on mine.
Tires: 235/35 and 255/30 Yokohama Advan S.




A tiny rub in the front with full compression and turning.

Looking forward to seeing your brake kit installed. Are you doing all four or just up front?

[Jaguar_7777]

Mate it should be all four , but due to other reasons its been delayed.

Hope to sort it out next week with the shop.

Fingers crossed it works out.

gawd hellrot is so sexy.

Your car looks great and the wheels look awesome. 3 questions for you:

1) Were camber plates absolutely necessary? If so, what camber are you running? Streetable? Are your fenders rolled?
2) Do you think these wheels will fit 17x9.0 ET30 (http://www.apexraceparts.com/ARC-8-1...l_p_151.html)? I am guessing yes because you got 17x9.5 ET35 to fit?
3) Instead of going with staggered 17x9.0 and 17x19.5, you picked square. Why? (I understand you may cite performance, ability to rotate, etc)

I think I will go with 17's after seeing how your car looks. I don't want to lose the great handling/streetability on the car by going with huge heavy wheels.

Looking great!

1. Yes, you need camber. I have 2.8 degrees. Streetable for daily driving...? probably not as you'lll go through tires quickly. No fender roll required.

2. Yes, 17x9 et30 will fit. While I'm running 17x9.5 et35, I am also using a 5mm spacer up front effectively making it a 30 offset. I needed the 5mm to clear my coilover perch.

3. I went square because I prefer having equal rubber all 4 corners for the track. While in theory it might help with longer life, I don't bother rotating. It's my dedicated track setup and I just wanted max rubber up front and keep the car as neutral as possible.


Keep in mind my answer regarding camber was specific to my suspension and my wheels (9.5 et35). Also certain tires tend to have wider shoulders, ie Star Specs and RS3 will run wider than say a Michelin PSS or Hankook V12. There's good info here on different 17" fitments for NON-M Z4's on stock suspension

Also before ordering, I would definitely ask Eddy @ Apex for confirmed fitments.

Best of luck!

[cmagalis]

This has been really helpful!

[cmagalis]

What is the highest offset you can have with a 17? I'm looking at 17s with an offset of 35 and width of 7.5". Car is an '03 3.0i, base model, stock suspension.

Very helpful thank you. I was afraid to go with the 17x9.0ET30s because I want them to look flush like yours. But I think it'll work out. I want to avoid camber plates and spacers... The car is my daily driver. Thanks again

For what it's worth all that rubber up front without camber will result in worse handling. It it's a cost issue take a look at Rogue Engineering's fixed camber plates. I had them and was able to get -1.8*.

It's more of a streetability and tire life issue... I'm still deciding whether I should copy your setup (17x9.5ET35+camber_plates) or just go 17x19.0ET30. I really don't want to start heavily modifying my street car ... especially since "my other car is a 911"
