Just finished one side of the car, springs are Tein, Koni shocks and M3 arms. Pretty straight forward but torquing the rear arms at the chassi point is a pain in the arse, no room to work. Tein springs have a 595 lb/inch rate which is higher than standard Msport 460 and M3 560. I used a 9mm spacer to raise the ride height a bit as I dont like it too low. I will post up a full review when I get the font done as well.
