Suspension?

What is the best setup for the E90?
I hate the way my stock 2011 335i looks with the big wheel gaps.

Thoughts?

One: Wheel gap is a pointless concern. Maybe you should trade for a low rider.

What should concern you is performance - stock 335i w/Sport suspension is a pale imitation of what can be. Drive a M3 - same car, diff suspension & differential. Diff engine too, but that's not the point. You'll see.

If you want to mod for performance, I can get your feet wet. If your concern is cosmetic, well, lots of lowering data in the E90POST suspension forum.

You said you can help get my feet wet. There is so much data out there I am on overload. Over the next 6 months, I'd like to tune, DCI (bms), new suspension and wheels.

Thoughts on the above?

Yeah, pretty conventional....chip's good, DCI not useful on the street. Most do shocks & springs first - I do LSD before that. Except M3, all models of 3 are much in need of more!

Rubber bushings gotta go - need M3 parts
Iron arms gotta go - need M3 parts
Rear subframe bushings gotta go - Need M3 parts
Front camber should be increased - need camber plates

If you're planning to DIY, check the suspension section at E90POST - HERE's my contribution.

That's a fantastic setup & DIY post you've written.
I'm inclined to do the suspension first. Where did you buy your parts from?
Do you have a list of everything that should be replaced?

Appreciate all your feedback

PS,
Why is the DCI worthless for the daily driver?

DCI adds no real power [street use] & stock's pretty good; reputed better at cleaning air. Vendors are linked in my DIY. You'll find HP Autowerks and Ground Control were my main suppliers - Sears for tools 'cause they're handy were I am.

Scroll through the DIY for parts list. It's fairly complete. Basically: All arms replaced w/M part equiv. Subframe bushings replaced w/M bushings. Shocks/springs spec'd by Ground Control. Couple o'sources for rear toe arms. Street/School kit packages many needed items. You needn't do the front tower brace - strictly elective. LSD by Wavetrac; installed by local speed shop. Sways are now M but if you're going with high rate rear shocks, may not have rear sway. Talk to Jay at Ground Control.

I use Michelin PSS on stock 18" alloy. Unlike nearly all 3rd party stuff, BMW wheels are rated to 150 mph, as are PSS's. Stagger a la Sport option for optimum handling.
