If your running the car with XXX-CR rear arms and hubs here is Jesse Robber's setup. It is an excellent setup that alot of fast XX-4 guys are running.

Front:

Front Shocks: Green spring/32.5wt/moulded 57s/ .090 internal limiting (I personally found this to be too much on a bumpy track so I run .030 limiting on a rougher track) #2 position (from inner) on tower, #1 position (from inner) on arm/ 21mm ride height (on a rougher track I got to about 23-24mm).

Front Links: #1 position (from inside) on the tower, grind carrier flat 1-2 gold washers under carrier ball stud, inner ackerman, standard lenghth link.

Rear:

Rear Shocks: White spring/ 22.5wt/moulded 56s/ .170 internal limiting (I personally found this to be too much on a bumpy track so I run .060 limiting on a rougher track)/ no external limiting/ #4 positon (from inner) on tower, #2 position (from inner) on XXX-CR arm/ 22mm ride height (on a rougher track I go to about 24-25mm)

Rear links: 5.5 on tower (outer most hole, middle row)/forward row, middle hole on XXX-CR hub (I believe Jesse refers to this as 5-b) with 1 washer under balls stud (be sure and grind away a small amount of the corner of the hub to allow the link full range of motion or at full compression the link can hit the top of the hub)/ hubs back

Misc:

Front- LCD shafts/steel outdrives/clicker locked down, direct drive/-1* camber, 0* toe.
Rear- Long wheelbase arm config/Steel Dogbones/Inner VLA on XXX-CR arm/Hubs back/ 2* anti-squat/steel outdrives/1/2* camber/.055 rear bar mounted off of the 2.5 (upper outside) holes on shock tower from the front side.
Drill and install sway bar link ball stud 1.320 from inner hinge pin center point on XXX-CR arm (this moves the lower sway bar mount out, making it engage earlier) According to Jesse you can run the stock mounting but you will need to run a .077 bar and it has a tendancy to strip out of the tower and will still engage later.
