The collars are set at the recommended preload and tight. Your other points were covered in previous posts.

Still having difficulty equalizing the height between the right and left rear. The right side is consistently 1/2"-3/4" lower regardless of the height of the spring perch.

LR - Ride height adjusted to 27 1/4" measured from level ground to the apex of the wheel arch. the spring seat is 31mm from the bottom of the spring hat to the top of the lower locking ring.

RR - Ride height adjusted to 26 3/4" measured from level ground to the apex of the wheel arch. the spring seat is 40mm from the bottom of the spring hat to the top of the lower locking ring.

LR shock height - note the connector from the shock body to the reservoir is at the limit of its adjustment range and cannot be lengthened further.

I kept lowering the RR spring perch to raise the right side but it would not come up even with the perch adjusted at the limit. Here the right side came up 1/4". There's no way the shock would adjust long enough to fit the lower bolt into its attachment with the perch adjusted like this.

I contacted BC Racing's tech support and the guy was helping me until 3pm (5pm EST), then he bailed so I'm in limbo for the weekend. He had me remove everything completely, measure the static spring height (180mm), reset the perches to equal heights (30mm), reinstall the springs and measure the compressed spring height with the car on the ground. The LR was 135mm and the RR is 125mm.

The only thing I can think of that would cause the right side to be heavier than the left is fuel in the tank. Even so, it's odd that I can't get the right side to raise.

If the right side was full while the left was empty it might cause the discrepancy. I don't know which side empties first. Tomorrow I will reinstall the shocks and top off the tank, add ballast to match my weight, then recheck the measurements.

Hot tip for anyone setting ride height - make sure your garage floor is level...

Rusty

Both sides of the fuel tank empty at the same time normally. Hard right hand turns, different story.

Your going to need to play with the endlink lengths on the swaybars to get the car to change right to left. Make sure they're not working against each other by checking the weight at the wheels.

Probably the right way to do it is
1) disconnect the swaybars,
2) get the heights just the way you want with the springs, need to check corner weights so you're not loading on diagonal tires,
3) Reattach the sways and recheck corner weights. Adjust sways to even them out to the weights they were before attaching them
