Rebound valving for live axle

[JBT]

I'm having trouble getting the rebound soft enough on my FJ40 with 14" SAW 2.0 coilovers mounted on the axles.
I started with a conventional 0,008 stack which was better than the 0,012 stack that the shocks came with. I have also tried adding more bleed by removing the screws and drilling one of the holes to 3/32, but lots of body control was lost by adding that much bleed.
Now I have the following rebound stack with one bleed hole plugged and one drilled to 3/32.
1.5x0.008
2x 0.90x.010
1.35x0.008
1.05x0.008
0.90x0.008
and a custom 0,7" washer beneath the top nut.

I really don't know which direction I should go. Remove shims so I have a 3 disc stack? Add more "flutter shims"?
Or is the SAW 2.0 piston so flow restricted that it's impossible to get it to work?

SAW pistons are restrictive.

be careful with the flutter, the shim will get sucked into the port, break off and do uncool things to the inside of the shock.

what are you trying to make suck less?

When I'm driving over rocks that are maybe 1 foot tall with a little bit of speed it feels like the car is falling down instead of the axle dropping out.

pick of your rig, where are you wheeling and what are you running on compression?

 

[RustyC]

How much preload are you running on the springs?

 

[JBT]

The terrain we usually ride in. Lots of smaller rocks, stumps etc.

Preload is about 1.5"
Compression front is a straight 0.008 stack.
Compression rear
1.5x0.008
0.9x.015
1.35x0.008
1.20x0.008
1.05x0.008
0.90x0.008

you need more compression. its bottoming not packing

OK,
It doesn't feel like its bottoming out when I drive off a ledge and the landing doesn't feel stiff. But maybe I'm wrong.
Would you suggest a straight 0.010 stack or should I start with adding some 1.05x0.010 and 0.90x0.10 to the stack I have?
