whats the best way to reduce roll in my 335i? i am very impressed with the stock suspension. its a good trade off between comfort and performance. however i'd like to decrease the amount of body roll during corning. i really dont want to replace the springs....is there a noticeable difference in after mkt anti sway bars in there cars?

Anti roll bar will reduce body roll at the lowest price point.

If only doing 1 sway bar, which one should be done first on the E90? Front or rear?

Just one bar and bar only? E93 front bar is the way to go!

M3 bars are great.

[CJ421]

M3 bars ... definitely.

I had the stock suspension plus the M3 sways, it made a big difference in cornering .... I could toss the car a lot freer than usual. No hesitation.

The rear is a PITA because you have to drop the subframe which is major $$ .... a few hundred bucks for labor. So just do the front. The rear only makes sense if you are replacing the subframe brushings with the M3 ones and getting an LSD installed.

With a 328 e90 non-sport would you recommend the e90 or e93 front bar?

On stock suspension, the E93 front bar.

How about an e92 335i? M3 e93 or e92? I do plan on getting coils (currently stock)

Yes it comes with sway bar bushings, he is referring to M3 subframe bushings since you have to drop the subframe to do the sway bar

to reduce under-steer, stiffen the rear sway bar.

Traditionally that is what one may want to do. However, with so much front roll and camber change induced by the roll the front outside tire is literally riding on its sidewall. By keeping the outside front tire more upright through the use of larger front anti roll bar(alternatively, you could use stiffer springs, lower the center of gravity...ect.), front traction is greatly improved...And guess what? More front traction and less understeer.

Do they make this M3 anti roll bar for a 2007 328xi? or only for i models?

The xi front suspension is very different than the none xi and M so the M3 front bar will not work. You will have to look into an aftermarket bar.

Will this fit the 335d?

Yes, you will want the larger E93 bar for the heavier 335d.

M sways will give you flat cornering.

BUT! Should not install rear without a Limited Slip Differential, which if you install, you will drop to your knees to thank GOD for.

It's that good.

While you're in there, replace the rear subframe bushings. Did mine in my garage. In fact, as I type, I'm sitting in HP Autowerks' parking lot waiting for them to open so's I can return their bushing R&R tool.

Worked great, and though any new procedure takes 10X as long as it might the second time, it wasn't difficult to drop the rear subframe and replace all the suspension parts. Really. Did ALL. Excellent experience!

Thank you. Any other modifications required? It's a pretty tight space.

[Bavarian13]

I assume that E93 bar is what I'd want for my E90 335. If so I'm buying it in the April.

No.
