Well, 10 days later and the lift is installed. I would highly recommend buying the upper A arm alignment bolts and washers before replacing your stock upper A arms. Or at least have them handy, if you are doing the lift install yourself. A few minor and preliminary comments for SLR:
-provide the tools the instructions say are provided (mainly the press)
-check leaf spring packs for proper center bolt arrangement (one nut facing up and one nut facing down; had to ream axle mount hole for proper install)
-check drill hole location on upper A arms for ABS line mount ( one drill hole was on the wrong side of the A arm and forced me to relocation ABS line mount)
-provide 90 degree grease fittings for high angle ball joints (bought my own)
All and all the install had a few bumps, but satisfied with results.
