I replaced my whole suspension the winter.
Had my share of issues & some problems ect, I recommend MM.

I have the Qa1 Kmemeber, but only because it is part of the turbo
kit i'll be getting...

MM coil overs, 4-bolt CC, subs, panhard, ect.

Anyway, I had alot of feedback that people really liked the MM K member for ride quality.

Here's my thread if anyone wants to read it.
Started with a recommended GMS stuff, even had Mr G himself pipe in.
long story, but I now only recommend MM, or Griggs.
Learned alot about suspension... More inside
