Default Question about Cusco Upper A-Arms

Does anyone know if the camber is infinitely adjustable (on a slider) or is it just preset bolt holes? If it's preset bolt holes then how do you get the camber exactly the same from one side to the other?
Also, do you know if all the cusco arms (camber, toe, etc..) come with stiffer bushings than stock?

From the suspension 101 thread, looks like they slide.

No, they are preset. Camber should be the same side to side because height should be the same side to side, and your bushing condition should be the same side to side. Weight distribution can affect it a bit but you should still be able to get it super close side to side. Mine was within .02 side to side every time I've aligned my car, which is probably 5 times since I put these arms on several years ago. I guess if you wanted to make it slide you could via a die grinder - I can't see the point in such a setup nor do I advise it. No idea if the bushings are stiffer than stock, sorry

Ok cool. Are you able to bring your front camber to about 1 degree without the arm hitting the frame of the car? I know ride height affects a lot, but at your ride height?
I've got the topspeed a-arms but at anything less than 1.8 degrees camber the edge of the camber arm knocks on the lip that protrudes from the frame of the car inside the wheel well. Its very annoying!

I can get mine down to -1.25 at my cars current height. I can measure the height tomorrow when I'm at the shop; I'm home now and it's not on perfectly level ground. I've never run into clearance issues with the arms, and my arms are still "unmodded" (some people slot the outermost holes to gain a bit more positive adjustment range)

BTW, a nice little package going out tomorrow night to you

IMO, camber arm bushing replacement is not worth the effort or the loss of NHV supression given the forces they see and what any deflection changes geometrically. Might you change them of a race driven car, yes. But not a daily driver, again IMO. That's not do say bushing deflection isn't a issue else where, certinaly is and it's been documented for years especially in the rear.

I have Cusco front arms btw.
