Hello all. Here is a little tip to tuning these shocks.
(When using bladder shock)
When aiming for zero rebound build them as follows.
Fill with oil and leave for air bubbles to go
Push the shock shaft all the way up
'Roll' the bladder onto the top as said earlier (allowing oil to be displaced by the bladder)
Fit the top cap WITHOUT the bleed/vent screw
With the shaft fully compressed then install the bleed screw
This should remove the trapped air behind the bladder.
A simple way to the add some rebound (can be done with the shocks on the car)
Remove the bleed/vent screw.
Fully extend the shock shaft
Re install the bleed/vent screw
This will increase the volume of air behind the bladder
The air behind the bladder (and therefore rebound) can be 'set' this way pretty quickly and easily.
I really believe that we do have the best and also most tuneable shocks available right now. Take the time to learn how they work to get yourself an advantage on the track.
We can have bladder or emulation shocks without the need to change parts
We have multiple hardness o-rings
Option to run 1 or 2 o-rings (1 spacer from the piston parts tree replaces 1 o-ring and separator spacer)
When using bladder you can leave out the vent screw to have a vented shock cap and tune with either foam or o-rings above the bladder.
Hope that helps
