On another note.

What a great read/write up.

Well done Steve. you bring knowledge to this forum.

If the coilovers are unloading then something isnt tuned right. its not the job of the spings to controll body roll . Thats what shocks and swaybars are for. Whats your combined spring rate . I know most people have to high a sping rate which leads to some bad things happening. Being a lightish truck u should probly be down below 150lbs combined rate . Alot of small buggies are down under100 lbs now.
If your sping rate is to high it will want to unload if u dont have high enough rebound valving. Problem is If u do have high reboud valving the wheel cant drop out fast enough when going at high speed. There is some really good info on priate about setting spring rate up properly

Body roll is a function of spring rate. The shocks can slow body roll but they cannot stop the body from reaching the same angle with the same given spring rate if the force is inputted long enough unless the shock is far too heavily valved. Sway bars will help with this as it is just another spring and the second stage adjuster on the coilover will also by increasing your spring rate as the car leans over.

250lbs is a massive combined rate, that's equivalent of 500/500lbs springs. Unless you have a high motion ratio (either IFS or trailing arms) you won't be anywhere near that. Even 150lbs is still a very high rate but it's getting into what most "comp trucks" with too high a rate are running. My Jeep runs a 60lb/inch spring rate, if it were a small buggy I'd be lighter again.

Compression valving is for when the shock is contracting and does not affect the shock unloading. Rebound valving can slow the rate at which the shock travels to full extension. High rebound valving can make the shock "pack" at high speed as the shaft can not drop out quick enough for the next contraction.

Hes got that under control. It is a race car after all...

I heard he came first and its got a v8 so that's cool
