BMW 435i Coupe on H&R Super Soft springs: Need advice/help

I plan on lowering my car but currently in the process of researching as much info as I can. I saw thor's car that was on this setup and the height looks perfect with the OEM 19's. He was running 12mm spacer in front and 20mm in the rear. But had rubbing issues in the front.

Does anyone here have a similar setup and experience with this that they can share.

My main concern is negative camber when lowering the car excessively. Which will wear out the inner part of the tires. I never had run flat tires before so I'm not sure how well they hold up to this kind of abuse vs. regular tires. But with the 1.75"F and 1.8"R drop affect camber much? Will getting an alignment after the springs settle in correct and bring back the camber back to or close to factory specs?

I can't stand the factory wheel gap, or any wheel gap for that matter and want to eliminate it all together. Plus the overall stance of the car looks much nicer when lowered.

My car is a 2015 435i M-Sport (Non-DHP) with OEM 19's 442

It depends where he's rubbing. Those are some pretty heft spacers on there, maybe a 5-10mm would help that. Once you're dropped see where the tire may rub then buy spacers that fit.

Once its dropped you can have it align back to stock or even more conservative. The camber along with toe and caster will need to be corrected to save your tires.

Agreed, thats a big drop. With that kind of drop and spacers you will need either negative camber or stretched tires to avoid rubbing.

By the way, our cars do not have capability to adjust camber.

yeah, neither did my Audi.

Just to be clear, I believe the rear has some camber adjustability but the front does not.

The H&R Super Sport drops the F32 coupe 1.75"F and 1.8"R I believe. Will getting an alignment done bring the camber back within factory specs at least? I'm concerned with the tire wearing out on the inside.

I just lowered my car on H&R Super Sport springs and have absolutely ZERO rubbing. I currently still have my winter setup installed with is slightly more aggressize than stock.

Front: 18x8 ET20 with 225/45R18

Rear: 18x9 Et32 with 245/45/18

Yes....I know the rear tire size is taller than stock. It should be a 255/40/18 but I got a good deal on the setup during the winter.

Also, check out posts from (betlion). He's running 20x10.5 in the rear and he says zero rubbing for him as well.
