this is funny, I called Tirerack to get my invoice for my Eibach kit, I then called Eibach to get some info on this kit's warranty.

Eibach in tern gave me the number for SPC to get a new camber kit perhaps under warranty. Well I mentioned to Eibach that perhaps, they should do some investigating with SPC for this issue.

Ok, well...off to call SPC now, this is funny.

Edit:
Well, Schmiddy SPC is sending me yet another kit just like they did for you.
How do your new SPC parts look so far?

I find this amussing, I called the Tirerack, to call Eibach, to call SPC about my camber kit. Wow, glad I paided the full Eibach price for the SPC kit. At least the tirerack had my invoice on file mine was lost long ago. Tirerack rules

So in the end, had I not purchased an Eibach kit form Tirerack I may not have had proof of purchase of an SPC kit.
