does anyone have a pic of some rca' i could see. i really wanna try to machine some up and need to see gow theyve been done previously. also which model sigma lower arms work and how much camber will i end up with? are there any other arms that work?
There are many more people on here who could tell you more about AE86 control arm options.
But as for the Sigma items, they are from the 80s ones with square headlights. The arms are 1 piece, have a press in style balljoint (not bolt in). Around 330mm long?
They are SO easy to find. I went to the wreckers and every second sigma had a pair.
I'd be interested to know how much neg camber you end up with. I've heard mixed reports of 3 all the way to 6!
If you add RCA's though the neg camber is reduced so take that into account.
If you want a machine shop to make them, you are best to take your steering knuckle and strut, and ask them just to make a spacer basically.
