Contrary to what some more anal folks will tell you, it is quite possible to achieve a good alignment with a lowered car without expensive aftermarket Caster/
Camber plates.......
I had a terrible negative camber after my spring install. here's my #'s
Before camber with upper OEM plate maxed out to +:
left = -1.9 right = -2.5
After camber with NAPA Camber bolt kit installed:
left = -.04 right = -.04
Part #'s for the bolts are 264-3638, you'll need two, about $20 each
You're welcome..
