Thanks guys. I am eventually trying to replicate the evosport m5 in terms of styling. So far so good. Looking at some splitters for the front now. Haven't decided if I want to go all the way across like Hamann or Hartge, or just the sides like Vorsteiner or ACS.
Regardless, I installed the RD Sport sway bars while I was under there and that made a good difference in the roll as well. My only concern is that when I removed the driver side wheel to install the spring, I saw that I was rubbing on stock 19s. So I lowered it and put the 20s back on, who knows what that will do. To be fair though, I was tracking the car with the 19s and the car was stock=body roll. It will be interesting to see how it does now.
