Can't wait for the review! I'm looking to get the same kit for my 135i.
Could you do me a favor and measure the GC struts for me? From the lip where it sits in the knuckle to right where shaft begins. I understand GC are a bit shorter than OE or off the shelf Koni. Also let me know if those camber plates are as quiet as stock. I'm currently running 400/700 springs with TCK kit and the ride is extremely comfortable. Did not like noisy camber plates so I switched to stock strut mounts. However, stock mounts raised the ride height more than I liked and I'm almost out of bump travel to lower more. Hence, me looking into shorter strut options such as GC offers. |

You like a firm ride. But w/LSD + Street/School, you really, really need that rear M sway. No biggie to install. . Last edited by CALWATERBOY; 04-07-2013 at 12:27 PM.. |

I'd wait until you do the LSD and subframe bushings to do the swaybars... the subframe has to drop at least a bit to do the rear sway, better to just do it all at once. I got my diff/swaybars/subframe & diff bushings all at once.

Dinan did NOT recommend that I do the rear sway until I got the LSD done at the same time because your traction goes DOWN apparently. Do them all at the same time and save money as the whole rear end comes down.

Why does he need an M3 rear roll bar with 700 lb springs?

Does GC use Koni external adjustable rear shocks (adjust rear rebound without removing from the car?) Quote:

I asked the OP to measure because I didn't know However, I did call Jay@GC and he told me they are 12mm shorter. Those struts along with lower height camber plates, a lower ride height is possible while retaining normal bump travel.
