Camber bolts are helpful. Running up to about -2.0deg helps plant the front without adverse tire wear on a street car. Even more if you don’t mind the tire wear
Yes, you can use camber bolts with the club sport.
But keep in mind the Mountune Clubsport is literally just Bilstein B8’s and Mountune springs. It would save a couple hundred bucks to buy Bilstein B8 (or B6) through Rockauto and buy the Mountune springs separately. The only difference being renting the spring compressor and either new top hats or transferred from your old shocks
