Been following the RX4 info as I am on the fence with this purchase as well. I love to hear the reports on how it has changed peoples cars. For me, every aftermarket chassis that says it is faster...hasn't been. Keep these success stories coming as it will help make decisions!
For me, my car has one bad tendency that I think is making it hard for me to drive. It seems that As I exit the corner the car is still in the corner (if that makes sense) Almost as if it is still rotating as as I come into the straight and it gets kinda twitchy.
