First post / Couple questions

[Cap'n]

Hey all--

Longtime M3Forum member recently upgraded to E90, who seem to hang out here (weird, but I'm in). Couple questions...

I'm considering 20" BBS CH-R in black, but TireRack's automated system is suggesting they'll rub. I've seen quite a few here with 20's and thought I would get some empirical feedback. Any reason 245/30 up front and 305/25 in back wouldn't work? (24mm offsets front and back).

I actually only considered 305 as that's what Tirerack online suggested out of the box for a 20x10.5 Rear. So could I just go with the same rim but 295 instead?

Does the answer change if I wanted to lower with either Eibach or H&R sport springs?

I also seem to hear a lot of what I think is flywheel chatter when idling the car out of gear. If I push in the clutch, the noise largely goes away. Is this normal? The E46 had noisy chatter on shutdown when the clutch was out. Wasn't sure if this simply happened all the time in clutch out idle on these cars.

Thanks!!

May I ask why you want to run a 60mm F-R stagger when the factory's only 20mm?

Do you not like being able to turn the car?

Short answer is that I don't want to. What I want to do is run these rims with H&R springs:

So the question becomes 1) is that possible and 2) what are the details that will make this work. For instance, based on your helpful albeit snarky feedback, I might want to consider 255/275. Will that work on 9/10.5 widths?

Appreciate your help. Here to learn.

I get that I'm new here, but not a noob to forums. I've searched. Mostly sales but I'll ask those selling.

That thread has 15 pages with no mention of 10.5" rims. Thanks for trying.
