I was referring to the stock Type S. The 54634 parts include revised mounting plates that incorporate the mounting holes for the rebound stoppers. The rear plate in the 54634 pack is now 3.0 degrees. I don't know if Tamiya made a running change to the regular Type S kit as I have a very early kit. I did find a noticeable difference when I put the 3.0 degree rear plate on with the rebound stoppers. Calmed the rear down just right.
