Hello everyone. So electrical / suspension is my weak points so I'm coming to you guys for advice. I have a 2011 335xi LCI 6MT. I'm looking to get KW V3 (because they don't make V2 for X-Drive). Is there anything else I should replace for better handling? Strut Mounts, Sway Bars, Bushings etc. I know people are on the fence with sway bars on an X-Drive because they said it increases its understeer while others say the opposite. Miles 43K. I just prefer a more connected steering, stiffer ride, less body roll etc.

Coming from a new F10 535xi to a CPO 335xi I feel as if the 535xi was better handling. Which doesn't make sense, RFT, heavier, skinner tires etc. I think it has a lot to do with the miles on the current shocks. But then again I'm clueless about suspension.

What tires are you running/Are you still driving on runflats?

Right now I have PS2 RF. I know they are horrible for handling and I plan on upgrading to PSS. 225/40/18 & 255/35/18 (Style 193M)

Then I wouldn't change the rear subframe bushings to M3 ones until you switch to traditional tires. That is arguably the most beneficial suspension mod after springs and shocks. Also look into if Meyle makes a HD bushing for the front tension struts when you switch to traditional tires. When you install KW v3 I'd replace upper and lower rear shock mounts at that time. Consider Dinan or powerflex upper rear shock mounts (I like Dinan's). You're stuck with oem lower rear mounts but I'd replace them. Your oe front struts mounts should be fine. Consider adding Dinan's front camber plates at time of susp install to reduce understeer.

Thanks a lot! Would M3 parts favor the rear? Because it is an X-Drive compared to a RWD E9X / M3.

Definitely the subframe bushings and to a lesser degree the guide rods and upper links if you switch to traditional max performance tires.

Thank you so much!

Hey man.did you end up completing the install? I am installing mine next week. The mechanic I am working with mentioned v3s have their own mounts...?
