[RAX335i]

Currently, my car has all of the typical m3 control arms front and rear, turner toe links, turer subframe bushings, Mfactory LSD, poly diff bushings, and BC DS coilovers. Every bushing that wasn't upgraded was replaced with a 335i or m3 bushing where applicable

I feel like I am still missing something in the way the car handles. The steering response is decent, and the car is definitely fast around corners, but it just doesn't feel quite right.

I will be doing stiffer motor and trans mounts, along with front and rear sways soon.

Is there anything else that I could be missing? Any input is greatly appreciated!

Camber and alignment and corner weighting?

more front tires (245/255) along with a sway set F&R (since you have LSD). The M3 strut bar and aftermarket combo (to form a triangle) and the DIY underbody braces help a lot, imo. A good alignment and a touch more caster felt good, too. mounts can be touchy with dd and nvh, but I liked the crisper feel. I definitely would NOT do stiffer mounts where you sit (trans), as the benefit is not worth it.

No personal experience, but I've read that the BC coilovers have pretty poor quality control. Read some owners found each coilover had a different damper rate when using the same setting. Maybe try switching those out for some high quality Bilstein ones?

Which tires do you have? And I agree that you could benefit from sway bars - they'll make a massive difference

Agree. Since he already has BC, revalve will be ideal. Also adjusting both compression and rebound at the same time is not ideal. I would contact Jonathan to see if he can revalve the BC. I'm not a big fan on coilovers with shorts suspension stroke. I know for the E46 the front stroke is 80mm. It's ok if you are running a high springs rate and don't want droop. He did my YCW coilovers for my E46.
