I have the front installed, you can feel a slight decrease in body roll for sure. I greased my polyurethane bushings and can still hear a faint noise under load. Nothing crazy though, still a good upgrade IMO

If you want more of a game changer, save up for the M3 front arms

I have an eibach sway. I noticed better cornering, and less body roll. I think it's worth the price.

I have the M3 front arms on my 07' 335i.....with the stock sway bars. It still leans over pretty good in the corners.

I'm also interested in ideas for a stiffer front bar......

The M3 front arms won't do anything to help reduce the leaning when the vehicle turns. That's what the front sway bar is for. Harder suspension would help too, but I see that you've already got the B12 ProKit so you've taken care of that already.

Feedback from a VLN e90 which I mechanic for, was that the front end pushed like mad with a solid front bar. I think it was an eibach one they tested. Either that or H&R. They found that a softer (stock) front bar works better. Thats on a car with KW 2-way competition shocks, and appropriate springs.

For street use, where you're not using all the grip a Michelin slick can offer, a fat front bar probably feels great on turn in. But mid corner you'll have less grip than with the stock bar, despite all the body roll that the stock bar allows.

This might be a dumb question... If the sway bar was upgraded, would an alignment still be a requirement or it is not required?

Iím on a e92 with Koni yellow and eibach springs. Body roll was originally atrocious and it got a little better with the upgraded suspension but I donít want the ride quality to get worse just to get better cornering. I think Iíll buy one and leave feedback afterwards

Also have m3 control arms installed

I have B8 with stock sport suspension. Might need to look into front suspension in the near future. What would you recommend? I have m sport suspension, and will soon have M3 front controls arms on

I would put the Bilstein B12 kit on your car and couple that with the Eibach Front & Rear swaybar Kit.

The Eibach swaybars are tuned to the springs found in the B12 kit.

I don't think the car will be lower than your car is currently, with the M-sport suspension. If it is lower, it will be negligible.

Yes the Eibach springs seem the be one of the least aggressive in terms of drop. If you are looking for a very clean flush look, you will need spacers on 18s & if you run 19s it will be perfect.

How much firmer is the spring rate for the Eibach springs compared to the OE m-sport suspension springs?

It depends on how soft/firm you adjust the setting to

They have a dampening setting you can use to adjust the firmness. It doesnít affect drop
