Springs or Coilovers?

It sure if I should’ve posted in the wheel/tires section or in here…kinda have questions on both…any help is appreciated!

I’m looking at getting some wheels in the next couple months. Specs are as follows:

Front 19x9.5 +35 245/40
Rear 19x11 +40 275/35

2019 330i RWD

First question, will I have issues with the 11s? I mostly see 10-10.5. I think it will be ok, but I’d like to confirm.

Second question, with those specs will I be ok on H&R springs? Or would coils be recommended to avoid possible rubbing?

Firstly, what's your goal?
If it's aggressive stretch fitment and not adding performance than that'll achieve it. Just know it won't be as simple as slapping on those wheels.

To answer your actual question, you'll want coilovers. But I bet you'll need camber plates and spacers too.

Because this is a forum I also need to add my opinion. Don't do it. Just get 9s and 10s or 9s all around and get the best tire you can afford instead.

I’m not going slammed and cambered and all that. Honestly the drop that the H&R springs give is perfect. Maybe a tad lower, but I’d be fine with that.

There’s another set I’m looking at that 9.5 +25 in the front and 10.5 +35 in the rear. Still recommend coils?

If I go with 9s all around, you think the +35 would be better than the +25?

FIY, I hated the H&R springs with stock shocks so much I popped for KW V2s.

I'll link Apex's research since they do a lot of the work for us. They have an example of a 9.5 front and it's pretty aggressive.
