Fitment: All BMW E82, E90 Sedan, E92 Coupe, and E93 Convertible( xi models excluded)

Enhance the cornering performance of your BMW with a set of BMW oem M3 anti roll bars. The m3 anti roll bar package increases front/rear roll stiffness giving the car crisp, quick turn-in response and balanced handling.

- Front sway bar-lightweight, durable 26.5mm tubular steel
- Rear sway bar-lightweight, durable 23mm tubular steel
- Come with all necessary bushing and bushing brackets(oem end-links are reused)

Harold,

I have a base 128i. Would like to reduce the roll in corners and improve steering response. Is there a benefit to this upgrade without replacing the dampers and springs?

Thanks,
JD

JD,

Yes, there is. These bars are bigger than what came on your 128i and will increase roll stiffness of the suspension and steering response will improve as well.

In addition, you may want to look into the M3 front control arm kit for even better steering response and give you a bit of much needed negative camber:

Choose the complete front and rear set or front only. Choose between the sedan/coupe bar or the slightly larger convertible bar.

This may be a dumb question, but do larger sway bars affect camber indirectly or directly? In other words, if the car was driving in a straight line, or if the car was cornering due to less body roll? Thanks!

The anti roll bar has no affect on camber while the car travels in a straight line. However, in a turn, the larger anti roll bar will reduce the amount of body roll or roll induced camber changes to keep the outside front tire more upright.

Does that answer your question?

Please PM or email if you have more questions.

It really depends what you are doing with your car, nothing in mandatory.

Yes, M3 ARB will work with stock suspension and aftermarkets alike.

How would lease-turn in specialist feel about the M3 Anti-Roll Bar being installed? Is this something you'd have to hide each time you go in for service or need to take off at lease turn-in? Thanks in advance.

No, you dont need to hide it at all. The ARB will look like it came on the car from the factory.

If you have no other suspension mods or simply on just sport springs and shocks, go with the larger one of the two.

I changed from the BMW PS front roll bar to the E93 bar and it is well worth it!

135i convertible suspension upgrade

wondering what your recommendation would be to upgrade my stock 135i convertible suspension as I've added cobb's accessport and now want street handling to match the enhanced torque and hp.

Couldn't sent you a PM.

either bar will work fine with the suspension you plan to install. The larger bar will give you slightly more roll stiffness thus less body roll.

For the best handling performance for your money, a good set of coil overs is the way to go. Koni, Ohlins or AST, take your pick. KW V series lacks linear rate springs and use lower quality dampers.
