So for Christmas I got some NM Eng Lowering Springs and 1 pair of H-Sport Rear Camber Links. I had a shop install them today and all seems fine. However, they put the camber links in place of the upper arms, not the lower. Looking online it doesn't specify if they are upper or lower, but it seems everyone puts them in the lower position. Will there be an issue running them in the upper position over the lower? The shop was able to get camber and toe correctly set up. Thanks.

 

They should have put them in the lower.

 

Are there any cons to running them on top? Just want to go back to the shop with a reason that they need to be flipped. I would just do it myself but now it's too low to get the car on my lift, which is why I had a shop do it.

 

When you lowered the car you pushed the rear wheels outward from the bottom. To fix this negative camber you need to pull the wheel wheels in from the bottom. By installing the arms on the upper you pushed the wheels out from the top which fixes the camber but increases the track of the car.

Traditionally people install them on the lower. Does this really matter, maybe it's a matter of preference, I don't really know, maybe someone else will reply.

 

Yea I did think that by installing them on top and fixing the camber that the width would be different versus the bottom. Thanks for the replies.

 

The upper arms have bump stops on them (besides the ones on the shocks), and there is a ride height sensor mounted to one of them for cars with xenon headlights.

Like Cerenkov said, your track will be slightly wider with the stock lower arms. I would be sure that you don't have any tire rubbing issues with the fenders.

So, if you don't have headlight issues or tire rubbing issues then you should be fine. The important thing is that you got the alignment done properly.

Have fun,

Typically the arms are installed in the upper position for strength and also to more easily adjust the rear toe. I've never done any kind of test, but I've always been told the lower arm is a better adjuster of camber. There probably is some geometry at play that can't be seen with the naked eye.

I would say that if you alignment and camber is set correctly, and the shop can prove it with a printout from the alignment machine, then don't worry about it.

 

I would just add the lowers when your ready for your next alignment. Also if you have BiXenon headlights make sure they installed the adjustment arm. It's on the driver side.

 

Cool thanks for the info guys. I have no rubbing issues, and don't have Xenon headlights, so I will just leave them up there.
