I have found that the o-rings are quite sticky and tight, so I decided to only use one instead of two. I replaced the other one with one of those shims with a lip on it. This made the shocks nice and free. Apparently PR have/are working on some different o-rings for smoother action.
Today I also drew the car in CAD and figured out a setup to run. I will write more about that tomorrow. It’s late. We only left the track just before midnight.

Perhaps you can choose this item, it should satisfy the enthusiastic who likes loosened condition to increase the grip.
Thanks.
Hi
is it possible to have a reference or the dimensions of the shim used to replace o-ring ?
Its the stock shim with a lip that is used in the shock at both ends of the seal stack.
thank you sir, you don’t have leak on shaft with only one o-ring ?
