It feels that the car is stiff, as it does bounce a bit, and the rear end is always kind of loose. My diff oils are 7 front, 5 rear. I have tried lighter shock oils, but still the 3 hole pistons. My latest oils were 32/27.5 F/R. I widened the rear end .75 per side.

I admit my setup skills are lacking. Got spoiled with the B44.2 which is easy to setup. I simply always wanted an xray kit, since they seem like super quality. It was an excellent build, but just trying to get that suspension dialed in. My next idea is to move the rear lower shock mount to the inner hole location.

I ran both cars last night. The xray was a handful for me. Both car run 6.5T motors, but the xray seemed much quicker, probably due to the low drag drivetrain. Just lacking keeping the tires firmly planted to the clay.

It's a keeper for sure. So any setup tips are welcome and would be gratefully received.

lift your rear diff oil to 7.

A few question
what 3 hole pistons are you using and brand of shock oil and air temperature.

I run on a similar surface, you can find my setup on the xray site. Just do not view them in the pdf format. Some of the values change (ackermann, offset and caster block setting).
