spring hitting upper phb after lca relocation brackets...what?
i lurk these forums 24/7 and have never heard of this happening.
why is it happening on the lowest hole and not at the middle?
i'm guessing an adjustable phb will fix it?
As the axle moves up/down it also moves from front to back to front again ; in a arc like this: ( .
So when it's in the middle hole as the suspension compresses the axle is moving forward, but when it's in the bottom hole the axle is moving back as the suspension compresses.
Do you have a 9" ford, or 12bolt chevy rearend, or stock?
Adjustable LCA or stock?

thought it was more of a right to left thing causing it than a front or back, i guess that makes sense. if it's front to back though then is a panhard bar gonna fix it?

i ordered RPM speed brackets but the hardware/instructions i received were from UMI. brackets aren't labeled so i really don't know who's they are hahah.
- The brackets are not made correctly
- The brackets where not installed correctly

here's where it's hitting. the upper arrow is pointing to the "upper phb"
you can see my sweet duct tape job with the hose underneath.
the lower arrow is pointing to where it hits the spring, where the tape is.

and yes i need new bumpstops
i set them back to the middle holes tonight and have about 1/8th inch of clearance now.
to switch holes i just drop the whole arm out. haven't tried without but i don't really think i could.
and these are slp eibachs in the rear. never thought of that. they came stock on some SS's and firehawks with the level 2(i believe) suspension package so i'd imagine it's not because of the springs.
Have you checked the condition of the front TA mount and bushing(loose, broken, bushing wornout)?
Are you LCA bushing in good shape?
I'll post later after I look under my car, for a possible solution.
could be an installation error but they're pretty far off.

My suspension's all aftermarket. I also have bolt in relocation brackets (BMR)on the lower hole, but I have air springs, not coil springs and also my wheels are centered in the wheelwells (front to back).
So here's some pictures I took of mine and maybe that will help you figure things out.
