So I threw on some FRPP lowering springs + a BMR adjustable panhard bar.

Before adjusting, the left wheel was sitting pretty much flush with the fender, the right wheel was about 2 inches in.

When adjusting, the front wheels were on the ground, rear wheels were sitting on ramps.

I used the string + socket method to center the rear axle and it was nice and centered.

Thew some blue loctite on the adjusting bolts and rolled the car off the ramps.

After rolling around for a few hundred km's the rear has now shifted to the left again.

Again today, i rolled the rear up on the ramps, readjusted, and as soon as I rolled it off and re-measured, it was back to the left.

Anyone with tips ?

TIA

I've found that it's best to adjust the panhard bar with the car on level ground, not on ramps or jack stands. It's a pita but doable. You can lift the car to loosen the jam nuts but then lower it to adjust phb length. Then raise the car again to lock down the jam nuts. Make sure the car is on level ground by measuring fender height on the left and right side of the car before you adjust the phb. This is important because the rear will shift on uneven ground.

+1, if the front is lower(on the ground) and the rear is raised, you then have less weight on the rear so it's not sitting as low as it will be when the car is level. You could always get the front on the ramps and then jack up the rear under the pumpkin and place jack stands under the rear axles where the springs are.

Just get the car sitting the same way it would be when it's on the ground so the weight distribution is the same.

Always adjust with the car on the ground. Since you have a BMR, it's an easy thing to do.

Good info as I will be getting my panhard soon.

Another plus of adjusting while the car is on the ground is that fact that you are shifting the entire body over with a simple turn of a wrench so you feel like superman.

Sounds good.

I'll give it another try.

Thanks !

When I installed and adjusted by panhard bar, the rear wheels were on home-made ramps that lifted the rear only 4.75 inches and the axle remained centered after all four wheels were back on the ground. I imagine there could be errors if the rear end was lifted higher by ramps when the centering adjustment was done. Also if you center the rear immediately after installing lowering springs, the rear could shift a bit once the springs settle to their final height after a few days and miles (or km).
