Honestly, there are others here who can recommend a better shop, and who have far more expertise than me.
I'm actually having ETREME difficulty with the shop I took mine to. I have another appointment on Tuesday, where they plan to FIX their mistake...and put back the engine-bay mud guards they literally *threw away* by accident.
Sad part is... The same shop did a great job with my 100 series some years back...but they completely botched this one.
Ill have more perspective on the BP-51's once things are properly adjusted for preload, etc.
Thanks, hope everything turns out to your satisfaction and I'll be looking for your updated posts on the suspension mod once it's tuned properly. Did you ever consider performing the install yourself, or is that out of the scope and equipment requirements for basic home-garage mechanics? I was on the fence regarding self-installation of the components, but your post makes me reconsider (assuming one can find a qualified shop).
