If the arms are adjustable, I would lengthen the lowers and shorten the uppers a bit. Just have to be mindful of pinion angle. If it is already at the correct angle with a bowed spring, use adjustable perches like mentioned.

no, you'll be fine to leave it as is but, depending on what track bar you're running, it may end up making contact with it.

I have the jks ones on mine and my springs are nice and straight.
Try the wedges and go from there.

as mentioned, the wedges only help a little - they will not fix the issue. only the JKS adjustable perches will do that.

Yeah that does make sense! Lengthening and shortening would turn the axle back to hold the spring straight..however the pinion angle would be off I would think. Is that what you're getting at?

What should the pinion angle be on a 2dr? So adjustable perches are the way to go, the Wedges are just a bandaid fix.

your rear drive shaft needs to be inline with your rear axle pinion.

There also might be a problem with your track bar binding at the axle bracket?

If your moderately handy with a small grinder and a welder it doesn't take much to cut off the originals and weld them back on at the correct angle.
