135i Suspension Upgrades!
I'm planning to do suspension ugrade on my 135i N54 AT [Mileage:117k km/ 72k miles]
Currently it's on some OEM struts and lowering springs. Tires & wheels: 225/35/19 & 255/30/19, front 19" x8.5J ET35 & rear 19x 9.5J ET46. All setups by previous owner. Thinking of the following:
Will be adding M factory LSD 3.46 as well. Maybe APEX 18" wheels if budget allows.. Notes: Struts are way overdue. It's very floaty and not taking bumps well. Fender rub after I replaced with MPSS4s especially on the rear. Intent: Overhaul all suspension componments. Keep it well for next 50k miles. It's my dd and will be tracking it. Would like to hear some advice from you guys!. Let me know if i'm missing out anything. |

Replace the upper and lower mounts as required. You should be able to plenty of camber with the OEM eccentric bolts. If you run out of adjustment or if the suspension is binding, you will need adjustable toe arms to free up the bind.

Anyway, someone offers me to buy KW Clubsport coilovers. Exact mileage unknown but it's 4 years old and serviced twice. Should I even consider? |

4 years and serviced twice? What was the reason for the services? Seems too frequent for normal wear and tear.

I would take a close look at engine, transmission, and diff mounts at that mileage. Might as well also re-build your shifter with new bushings etc (oem or other).
Car will feel fresh as ever after all that. |

Also, the rear M3 control arms doesn't make a big difference unless you replacing for wear&tear then go ahead. Otherwise, I'll opt for SPL rear control arms to have more adjustment. As of now, my front camber sits at -3.0 and rear at -2.3. Next on my list is wheels and tires. Trying to fit a 255/275 tire setup and it's really a headache unless I decide to do a 1M conversion.

Additionally, where the benefits shine are the coilover options available when doing the full M arm and knuckle setup. Otherwise, its only really the guide arm and toe arms which are different in the rear. The toe doesn't fit, so have to go aftermarket/custom there.

Rubs the filler neck a bit in the rear. I have massively rolled/pulled and cut the rear fender lips and bumper tabs so I'm in the process of spacing things out a bit, thinking 10mm rear (for function) and 5mm front (to even it out visually again). Mods I've done are substantial, but the setup should fit with stock everything other than the 1M front which is obviously required. Cheers.
