Offset upper A-arm

I'm starting to put the hotchkis TVS kit in this week just wondering how many who did this had to use the offset a-arm to make the car line up after this install.My car was pretty heavily "shimmed" befor I started and just eyeballing it lowering it 2" in the front seems like I could have some trouble...so how many had to do this'is there any way to tell if this is needed or not at this point,where did you get you offsets etc etc etc

Re: Offset upper A-arm

Depending on which way you install them, you either gain or lose some shim, not much tho. The upper a-arms should slant slightly up at ride ht, so lowering puts them at more of an up angle, which makes them shorter, which means you need less shims to get the right camber. If you had a big stack before, you should be ok.

Jim I think your car is lowered from what I remember and I know you have experience with this so here is my concern...When I had the front clip off the car I noticed I had considerable top of tire in towards engine...not a front in guy so i dont know the term I guess this is negative camber? Any way top of tire in and alot of shims. Now if I got my head right,and I put in drop springs I'm gonna increase the amout of top tire in towards the engine...right... and if so I'm gonna run out of bolt length with shims before I ever get it right...is this correct?

Re: Offset upper A-arm

If you were looking at camber with the suspension "up" ( as in car above ride height) forget you ever saw it. No basis in reality there. With the suspension against the bump stop on the upper a-arm, there will be SEVERAL degrees of negative camber, so much that when you try to drop the car, the suspensaion will "bind" and hold it up because the front tire contact patch is an inch outboard of where it should be.

To get any idea of where you're at camber wise, you need the car at full wieght, and then roll it back and forth at least 30 feet to settle the suspension.

Re: Offset upper A-arm

MOOG's are right at a 1/4" offset and can be used both ways.

I have them on my car now to pull the top ball-joint in!!
