Jay, I'm going to be running on my stock weaves for a while, and need new tires for them, I also want to push them out a little, they sit WAY to far inside the fenders.

They have different size tires on them right now, the fronts are stock size, and the rears have 205/60/14's on them. I'm probably going to get ZE-512's on them in that same size all around.

What's a good amount to space them out to, that won't require excessive fender work? My front fenders are rolled, rears are not, and I'm on IE3's with Konis.

15/20 is what I came up with as the just-barely-up-to-the-stock-fender setup.

Sweet, thanks man.

Getting a ~25.5" tire in the front well of an E30 will be extremely difficult. If you switch to a 235/40/17, you'll be dine.

Thanks for the tips/comments!

I actually made a mistake. I have 235/40/17 in front.

Guess I should have posted here:

Running 16x9 Borbet Ts (et15) with 215/40 R16 tires.
10mm spacer on front
20mm spacer on rear
AGRESSIVELY LOWERED.

I'm about to fix the rear geometry by replacing my subframe with one that has the toe/camber kit welded on. I want to get a little more life out of my tires, so I'll probably fix the camber a bit. I'm afraid that if I do that, the 20 mm spacer will be too much and I will have some fender interference (already rolled). There is some interference already when really loaded up, but that's not very often.

So my question is: What size spacer should I get? Is it as simple as taking 5mm out and I'll have that much more clearance? Or is that enough? I keep meaning to look under the car and see how much room I have on the inside, don't want to clear interference one way, and start some the other... (How much of a spacer do I NEED on the rear to run the 16x9 et15s?) If I have a smaller spacer, could I maybe have more tire in the rear? Not crazy about running staggered, but it would be fun to try for a bit, I think.

I'm going to get custom spacers made (again) so I want to know what to tell Fred.

If one were to run 16x9 wheels. (offset not sure but maybe 20), would 195/50/16 tires fit to give it a stretched look or would it not be wide enough to fit? My friend ordered some 16x9 wheels and wants a stretched look. I have 16x7 remembers with 195/50 and looking to get rid of them for some 205s or 215s so my friend may buy my current tires off of me if they fit. Thanks

I have a set of 17*7.5 et 35 bbs wheels. I have a set of 245/40/17 & 245/35/17; would 10mm spacers and rolled fenders give me a decent ride without rubbing, any unforseen problems? Thanks.

I have exactly the same setup as you mutty -- 17" BBS RCs w/ET35 and a 10mm H&R spacer -- and my 215/40/R17 Michelin PE2s fit perfectly on H&R/Bilstein Sports. No rolling. I do however seem to have a bit of fender gap (about the size of a man's fist) in the front. The rears however have no issues. Sorry I've got no pics, I'll see if I can snap a pic if you want one though.

I tried to fit them without spacers as a test, they rubbed in the front without the spacers.

Hi There,
What is the lowest offset that will fit on an iX with 17X7.5's assuming a completely stock setup?
Is there even a chance for ET18?
Thanks.

[nando]

no, too low. you could cut the shit out of the rear fender flares and run a 205/40-17, that might work. but if you want to run a 215/40-17 or even a 225 stick closer to ET30. it will still fit flush with the wider tire.

Thanks for the info. Another ones bitten the dust. Now off to TMS to get studs/nuts.

Reducing your negative camber will definitely also reduce your fender clearance.

Your rear wheel will actually clear the inside without any spacer at all by over a cm. You can back down the spacer to any size you want, or even none at all.

Even with no spacer, I still recommend 215/40 as the widest, unless there is some moderate/heavy fender work in the cars.

Absolutely insane stretch going on there. It's theoretically possible, but you will likely have trouble finding anywhere that would mount such a setup together. I wouldn't do it.

Both tires are too wide for the wheels. You can do a 235/40/17 (just barely, given the width of the wheel), but that's it really. With rolled fender you'll be fine.

That said, I know I've seen it done by another member on here (245s on a 17x7.5). I still can't recommend it though, that's some serious "over-tiring".

Just curious why my 15X7 Borbet type bs (et35) rims with 205/55 rub the inside front struts badly. Do i need spacers for them, if so what size do you think, also do i need smaller tires for them would that help out.. They bolt right up just rub really bad..Cheers in advance
