So, today was my first day.....I had a blast!
I love driving the z4m more than any other car I have driven so far, and I cant wait to go back again. Unfortunately, I got a terrible spring rates so I was dancing all over the track... I had to put the dampers very soft to try to balance the spring rates 700lbs/850lbs. I noticed that those are terrible for my car.....not enough weight on the rear to support that rate.
Still had lot of fun! ran with 275/35/18 with 9.5x18 et22...unfortunately the rear rubs a little...I will have to pull a little more....funny is that the front doesnt rub!
The PFC bbk....omg...the best bbk out of brembos and stoptech....braking power is instant!
Well I wont even share my damper settings, because this was a disaster....so I ordered 650lbs/750lbs....hope I am making the right decision.
