He's rubbing on full lock on the front fender liner, not over bumps or anything. Most people rub on the front liners but just dont care because they hardly go full lock. Tho that being said I have 245/40s which are taller and barely rub at all at full lock.

I run 245/40 Dunlop ZIIs up front on ARC8s

-3* of Camber at 8 Degrees of Positive Caster and a 5mm spacer and I don't rub, although my front fenders are indeed rolled to avoid a rub under full compression as I'm quite low:

Same. What are you running out back these days?

[jmc777]

I'm running 235/40 PSS on arc-8s all around on my 128 with stock sport suspension. No rubbing at all.

-2* degrees with 245s.

rubbing a bit on slightly rolled fenders. need to fix that

I was under the impression caster wasn't adjustable on our cars? I know the m3 control arms add positive caster along with .75* neg camber. You guys think the m3 arms would give me enough caster?

I would like to know the answer to this. I have been told the lowers provide approx -0.7 degrees of negative camber, by pushing the bottom of the front wheels out. Hadn't heard about the uppers impacting geometry, just that they remove flex with stiffer bushings and firmer that the stock stamped steel arms.

I'm running coilover suspension with camber and caster adjustable plates

OEM suspension has limited adjustments for camber.

You do not need any more caster. Positive caster moves the wheel up front in the wheel well. More caster and you will rub more on that fender liner.

Unfortunately, caster isn't adjustable.

Ok thanks. so then would negative caster help if I bought some adjustable camber/caster plates?

Most likely, but cannot guarantee it would solve the issue.

I don't know if the 135i has less fender room, but I'm running max caster and from lock to lock I don't rub.

Dang that's a lot of camber. So with plates it sounds like it's doable...they're on my 'to do list' but front sway and limited slip come first. So I can't say it's a huge priority, summertime i'll get around to it. 245/265 would be very nice and neutral I bet.

I'm wondering if the Bridgestones run a little wider than the PSSs and other options in that fitment. Same deal here, more or less--installed staggered EC-7s with 235/40/18 and 265/35/18 SO-4s on a stock suspension '08 135i last week, and experienced immediate audible rubbing up front during cornering. After getting the car up on a lift, it's apparent the fronts are getting some pretty substantial rub on the fender well, as well as lightly touching the strut on the inboard side. The rears seem fine. Given that I called Apex twice to confirm that fitment (tire size/wheel combination) was a no-hassle setup on this car, I'm not excited about this development.

The options seem to be to change the tires (either the sizes or brand) or try some additional hardware tweaks to get this wheel setup to work. Camber plates had been next on the list of intended modifications anyhow, so we're we're going to try Vorshlags and 3mm spacers this week to try and gain the necessary outboard and inboard clearance--will update accordingly.

Ok what's the deal! I'm about to buy apex EC-7 with 235/40/18 front and 265/35/18 rear and was told I would have zero rub issues even if I'm moderately lowered.... And the tires would be Michelin PSS's which are considered some of the widest... I don't want spacers or crazy camber to make these work
Please keep this updated
Also are you a vert? My phone won't show sorry.

Just measured both the width and height of the fronts. 25 1/4" tall and 9 5/8" wide. Not sure how much that would change with them actually being mounted on the car.

[135iam]

This forum needs 135i/128i 18x8.5 +45mm front tire sticky thread.
1. Stock suspension these tires fit
2. Stock suspension these tires rub
3. Tires that fit with added neg camber
4. Tires that fit with added neg camber and roll or pull

And then there are spacers, hell I thought we bought these wheels to avoid spacers!

That's pretty close to what tire rack lists 25.4" and 9.5" for the re-11

Have you pulled the alignment pins, loosened the stock top hats, and maxed out stock suspensions neg camber?

No, wasn't sure if that would help or not. Plus If I did that the rim would most likely rub the strut. I have some 5mm spacers but lost the extended lugs and wasn't sure if using the stock lugs was a good idea.

That is on the light side of camber for me

It is going to be an AutoX/Track car, so more camber the better. Plus I had to clear my strut/spring so I needed that camber.

17x8.5 ET40 Square

Rears need some more work, but I can get them to fit with high compression turned, it is just the low compression I'm dealing with some rubbing

Dang. Yea makes perfect sense for a track setup, but on city streets I’d imagine 3 degrees is going to hunt all over the place and chase all the little cambers in the road. Tire wear aside.

So getting back to the original point- on a street driven E8x, you aren’t fitting 245 up front without making some significant alterations. Stock ride height maybe, lowered no chance unless you have camber etc similar to you track-specific setup. I’m running about 1.5 of camber up front, and there is no way a 245 would clear the strut or the fender.

I’m sure it’s an awesome track setup though.
