As my current monoball tops that came with my JRZs are getting worn, I'm starting to look for replacements and finding it interesting for my C4S. I'm trying to understand the design differences between the C2 and C4/Turbo plate design and what would preclude the use of one on the other. Going by pics only (Tarett, etc), it appears that the C4 variant has a slight angling of the boss relative to the base.
The C2s appear to come in both the triangular and flippable plate (GT3-style) and the boss is square to the mount
The plates that came with the JRZs are like the latter, hence the question.
Here are pics of the JRZ C2 and C4 plates. Blue is C4. The only difference is the angle of bear bore. You can just replace the bearing in the plate so you don't need to buy new plates.
edit: I meant bearing bore, not bear bore.

Cool, thanks Tom! I assume bear had to do with getting the circlip and pressing out the bearing :-)
Welcome. Not at all, the bearings press out easily using a socket in a vice. Didn't need to get a bear involve.
PS- I prefer the JRZ plates because the centerline of the bearing(height wise) is the same as the centerline of the plate to give the shock more travel(increased available stroke) for any given ride height. Personally I want as much available travel as I can get with a set of shocks.
