Art arms vs. stock?

what is the difference in drop with the ART lower control arms as opposed to just regular 1 cup and stock control arms? I planned on putting some on my 85 but i dont want to get them if they wont allow the front end to drop another 2 inches. just wondering if anyone knew. thanks,

Darrell

take it for what it's worth, i had ART uppers and lowers, with drop spindles on a 94 i bought already bagged with small wheels. didn't own the truck too long so i don't know any long term problems or anything. but i know i had a bunch of residual space in the bag when laid out. from what i've heard, most people will tell you don't even waste money on control arms unless you're going larger than a 20".

i have 22's and i was just going to reverse cup my lowers 2 inches but i would much rather get some tubulars. oh and the truck is an 1985 c10 that im BDing right.
