The Clubsport and Motorsport are generally valved exactly the same (glagola1 could elaborate on that I think) except that the Motorsport have more adjustments within the range.
Mine was based solely on price. I supplied Fox racing canisters and did SA 8300 Penske's for $2500. Clubsports with slight adjustments to the valving would have been near $4600.
I've been told that the KW's are exactly the same internally as a Koni although they seem to valved a little bit better. Other than that I don't know a whole lot about them.
What I like about the Penske's is how modular they are. You can start with a SA shock that is Rebound, Compression or both on one knob. Upgrade to the 8300 canister for $350-360 a corner. Or to the 8700 series canisters for $600 each at any point you want. You could even go to the Regressive piston used in the F1 cars right now for $1700. Moton's have one piston and one canister and it costs $250-300 per shock to revalve (not like you would really need to though). That being said - Moton's piston is very different than the Penske and you don't need all kinds of different designs to get different characteristics, you could just change the size of the springs or valves. I think they are very similar to the Koni 28 Series shocks that use cartridges instead of a "piston".

It would be interesting and he's always been open to doing car stuff.
I've been told the same thing about the KW's
They list the same size piston for the motons and since I'm not changing spring rates I guess the CS would work out great. Speaking of spring rates, what spring rates are you running?
I have a CR front bar 225/255 on stock wheels and it just feels like the car could use more spring in front. I have 571 all around which is the stock KW CS rate. I don't understand why they use the same spring rate front to rear?
I'm a bit confused about a cartridge vs piston. I think I may have figured it out (maybe)
The piston is positioned on the end of the shaft and its whole purpose is to push fluid through the valving located at each end of the shock?
The cartridge is the one that is surrounded by the shims located at the end of the shaft.
I probably have this all wrong since I couldn't find anything about it.

Cartridge is a Koni thing only.

Instead of multiple shim configurations and individual shims, you just change out the entire rebound/compression cartridge for another one.

Oh yeah - I'm running 850F/700R. No rear bar. Big front bar set really soft. Only autox'd it and at higher speeds on old RE-11's it can get a little twitchy but other than that it handles great. And that was on the Koni's - I'm looking forward to this season with the new shocks/LSD.

Thanks for the explanation and the link.

FYI for anyone wanting to use Bilsteins. The lower spring collar is not made for 2.5" springs. Just found out it is 2.7" in diameter... Collars getting sent to machine shop tomorrow...

This is for the PSS9's? Or are all their series the same?
