Thinking about running a long z-link setup w/ a biscuit bar and short panhard bar behind the rearend. I am going to try running the slider on the lr on the birdcage and the shock on the swingarm it's self. This setup will be used on a 2650 lbs mod w/ around 385 hp and torque. Any input on this would be greatly appriciated. Thanks.

Long Z-Link on both sides? What bar lengths?

Swing arm both sides?

Myself, i run short rear bars, we like it better. The short bars act faster, and produce needed results faster.

If your on a really big sweepy track, long bars maybe the trick, but the short panhard behind may not be the ticket.

I imagine he means the long rear bars on the z-link. The reaction time is similiar to the shorter rear bars but the longer bars create more roll steer.

The only part of the setup you posted is the shock being mounted on the arm. It will work but you will have to be aware that the shock will need to be much stiffer than if it was mounted on the housing. I would rather see the spring on the arm and the shock on the housing. Also with a z there isn't much point in mounting the spring to the birdcage, there isn't enough birdcage movement to offset the inconsistancy of having the variable motion ratio that you get by mounting it on the birdcage.

In a limited horsepower application you want to build a smooth/predictable suspension free of jacking and roll steer effects because they are paracitic to HP. I think you are on the right track. The only changes I would make would be to goto an equal length z-link with both springs mounted on the arm, and unless coilovers are legal mount the shocks to the housing.
