I bought and installed a set of QA1 front coil overs in the car and LOVE the adjustability of them!!  So now I want to throw a set of coil overs in the rear.  But was just curious if somebody could show me a part number of a coil over they used or something just so I could have a guideline to go by.  I want to make sure I get the right length and spring rate.  Also, I am planning on using the stock shock location on the housing to mount them, so I was wondering how have some of you fabbed upper mounts?  Any guidance is GREATLY appreciated!!  Thanks!!
