The Pro kit came with 9805504 piston shaft which is slightly longer. You would have to special order it from Banzai in Japan. Otherwise, you can use a TC piston shaft, to give you more ride height.
On my car, I'm actually running the TC damper on the rear, because I have the R spec lower suspension mount, which even lowers / lengthens the mount.. So the M chassis damper was coming up short.
