19x9 ET 39 square set up on E90 LCI front tires?

KAAZ · 08-10-2016, 01:06 PM

Hey everyone, I'm a bit of a noob here and starting to do stuff to my BMW for the 1st time. Although I've previously owned a BMW before, this is the first time I'm modding a BMW. So I was hoping I could get some help from you guys. I have a E90 LCI and looking to mount square setup 19x9 with an offset of 39. I know in the back it's 255/30/19 but what about the front? Can I run the same size?

The car will be lowered on H&R sport springs. I've searched the forum and online but didn't find anything concrete. Closest result I found was people running 18x9 square set up with 255/35/18 all around. But those are 18's and I'm mounting 19's. But any help is much appreciated. Thank you in advance.

Just going to say a 255/35/18 is the exact same size (externally) as a 255/30/19. Not going to comment about the front fitment on your LCI since I think pre-lci fitment is slightly different which is what I have.

I know the rear-ends of the LCI's have about an 8 mm wider track from what I read but fitment shouldn't be an issue on the rear. Just the front I'm concerned about. If it is the same as pre-LCI's then I should be good as you are another example of someone running a square set up with 255's. From what I've read, LCI and pre-LCI are the same in the front, just the rear has a wider track. Hopefully someone can help answer that. Do you have any rubbing issues by any chance? thanks for the reply by the way.

I don't rub at all with a 255 front. 18x8.5 et23.

Running 255/35/18 PSS fronts on 9" ET30. Lowered on ST-V1's. I rub on large bumps at higher speeds. Hoping to pull my alignment pins to get a little camber and get rid of the rub.

Seems like it should work then. My only concern is that the offset is 39 so I don't know if it will rub against the suspension. But seems you guys have slight rubbing issues towards the outside with lower offset's. So I'm thinking it should be okay. Thanks for the help everyone.

I'd probably get a spacer. I'd bet you'll rub on your suspension with that offset. Also, take the camber pin out and max the camber out on the stock top hats. You won't regret it, these cars desperately need more negative static camber.

et39 is too much for the front, you'll need at least a 10mm spacer, if not more depending on what tire you want to run. For anything fatter than 255 you will also need about -2 degrees to clear the front fender, exact amount dependent on how lowered you are.

Rear fitment should be fine, maybe a small (3-5mm spacer) depending on the tire and how flush you want it

I'm running a 19x9" ET35 APEX EC-7 Wheel up front on my Pre-LCI 335i with no issues. Tire is a 245/35-19. A 255/30-19 is going to be close. The 245 is already close.

Rear is nothing for a 9". I'm also running 19x9.5" ET33 APEX EC-7 Wheel in the rear with 275/30-19.

No issues. Fenders not even rolled.
