I'm installing H&R Sport Springs and Bilstein Sport Shocks (not Neuspeed) Saturday...
 

What perch should I use for the rear shocks, the factory set one or lower? I want it to sit level.

my 2.8 sits level with......
 

bottom on rear and 2nd one from bottom on front.

if i could do it over again I would go 1 more perch higher on each. (2nd from bottom on rear, 3 from bottom on front) I can't even go through car washes anymore and speedbumps have cranked my frame a few times. Not to mention scraping my front lower valence on steep driveways.
