So I'm considering having a shop relocate my rear upper spring perches. I have my pinion rotated quite a bit and my bumpstops aren't aligned very well and theres a good bow to the springs. In fact, the bump stops pop out often when articulating due to the angle it meets the lower perch. My concern is if they straighten out the rear springs, it will add additional lift and cause increased rake. At that point I'll be chasing the front springs to match the height. For those that have had this done, did you find that additional ride height was added to the rear? If I can anticipate it, then I would consider switching to a shorter rear spring at the time of installation instead of going higher in the front. FWIW, i'm on 2" BDS springs now with a UCF extra clearance skid and traditional SYE.
