The drive home after the install I could tell a noticeable change in the steering. I was concerned as some M3 owners said they did not notice a change when they drove their M3 and a M3 with the competition steering rack. The steering feels sharper and I can notice I do not have to turn the wheel as much when making hard over turns. It is not major change but enough that makes the steering feel closer to the 1M which was my goal. I believe that if I did try the ZHP rack of a 330 ZHP it probably would feel a tight as the 1M but I did not want to go that extreme.
For kick and giggles, I wanted to see what 10 years of ownership looks like in paperwork. It means a whole lot of paperwork in a hanging folder that I will have to split into two eventually.
