For some reason, Alex Racing does not include the droop screws, but 4 of 3x12mm screw should take care of that

Steve, Since you did so well over the weekend with those new parts, care to post your setup ? I assume this is an asphalt track.
The biggest thing that helped I think on the car right now is the shorten camber links (in the front especially) This is on a really high bit asphalt track:

Front:

Upper shock position: outter most hole
Lower arm position: outter most hole
Oil: 40wt
Spring 1.5 / 6.25 coil alex spring
camber: -1.5 deg.
toe-in/out: slight toe-out (1 deg)
no sway bar
ride height: 4.5mm
droop: 2mm (we are now measure droop by the amount of mm above ride height) so if ride height is at 4.5mm, when we lift up the front, it is 6.5mm so droop = 2mm (Someone correct me if I'm wrong)

One modification I'm using on the front are the SpeedWay pal camber link mount and their C-hub which has a king-pin style camber link mount.

Rear:

Upper shock position: 1 in from outter most position
Lower Arm position: outter most
Oil: 35wt
Spring: Yokomo White
Camber: 1.5deg.
Toe-in/out: 2.5 deg (using off-set ball stud in the rear suspension ball)
no sway bar
ride height = 5mm
Droop = 2mm
Roll center: Raised 0.8mm using A6511 shims
R3 rear hub carrier

I ran the Mazda 6 body on Saturday, and it worked well. I also went practicing today, and actually found the old Protoform 2.0 stratus to be a little bit better than the Mazda 6 (Unfortunately Protoform has stopped making the 2.0)

Steve,

Do you put the 0,8mm shims under the pivo balls in the rear or just under the camberlinks on the top plate ?

STEVE

someone else measuring droop correctly

makes me very happy as now everyone can use other peoples set-ups easiely without worrying about tyres sizes making a difference to the droop settings !!

whats the difference between the r3 and r2 rear knuckles? will the r3 rear knuckles fit on the r2? And if so what handling chnage will it make
Also have you ever used the offcenter balls to alter the whellbase? or trackwidth

I believe Steve mentioned that with the R3 rear knuckles, the drive shafts are more parallel when at racing height.

I've seen that one before... I thinks it's a pal barracuda r1. I'm not entirely sure though.
