On Saturday a friend of mine who also owns a TT RS took a ride with me and immediately noticed that the car was more compliant and easier over the bumps than stock.
High speed handling is also spot on, with a seamless transition from turn in to corner exit. I also did a few high speed braking runs and the tail definitely stayed in check without much drama. So far I am very pleased and amazed at the completeness of the system. I am looking forward to testing it on track now.
