Absolutely.
I bought the full Eibach front end, 2 new springs and 2 new struts. I had a buddy install it in his garage with cheap spring compressors. Somehow during installation, something was messed up. While at the alignment shop, the top nut on the passenger side sheared off and stripped the threads. The driver side is still on, but there are no threads above the nut. Something wasn't done correctly.
So after I take delivery of the 1 replacement Eibach strut next week, I'm having the shop disassemble and reassemble everything properly. Everything is 100% new, the existing components having less than 10 miles during the drive to alignment shop.
Moral of the story, pay the money and do it right the first time! Doh
