How Necessary are Rear Camber Arms for Mild Drop?

[3002 tii]

I really don't want to get rear camber arms unless truly necessary seeing how they are a major PITA to install. I just wonder though will I really have that much excessive negative camber in the rears if I drop 1" or so? Assuming I go 1" lower, should I not be able to adjust it back using the stock arms?

the eibachs i had lowered the 3.0si about .75" in the rear... i was able to max the stock alignment and have whatever toe setting i wanted. while it is possible that going down an inch from stock would limit the same freedom of alignment choices, i don't think you'll have an issue with the stock arms.

so how much camber did you end up in the rear?

i can't recall. it's here in the forum somewhere... i'll start searching for it.

Front Camber = range of -0.5 deg to -1.4 deg
Front Toe = +0.05 deg to +0.18 deg (toe in)

Rear Camber = -2.6 deg to -3.1 deg
Rear Toe = +0.17 deg to +0.37 deg (toe in)

on my 3.0si with eibachs i was at -1.5 in front and -3.1 in rear (both camber). toe for both was set at mean for both front and rear. no adverse tire wear to report.

yessir... from ZSP susp to the eibachs. the pro kit was much less "crashy" than the stock springs, but i don't have an accurate compairison because i switched from 225/40r18 frt and 255/35r18 rear RFT's, to 235/40r18 frt and 265/35r18 rear non-RFT's at the same time the springs went on. so basically, softer and taller tires, which was most likely the biggest improvement in ride. if i had to do it again, i'd go to -1.7ish for front camber on the same wheel, tire, and spring setup to combat the very minor front liner rubbing that seams to plague the non-///m cars.

Ok, thanks for that info !
