Get this - I had Eibach installed a couple weeks ago by a suspension & wheel specaility shop & told them to put on the 12mm spacers in back & 15mm in front. I pick up the car and notice they are put the 15mm in the rear. I asked them about it & the owner trys to tell me "it is illegal" to put a lager spacer on front than rear, & refuse to do it.
So we have a few words and, because they still owe me the alignment, I don't get too off the handle. I'm having BMW put it right tomorrow along with my 1200 mile service.
There's no rubbing with 12 in front & 15 in back either.
You can't reason with some locals. They are hardheaded.
