    Default Camber Bushing Kit - Lower Control Arm

    I am rebuilding my front end this weekend and during dismantling I came across a suspension upgrade the PO had installed. After searching here I found this thread:

    http://www.classiczcars.com/forums/s...ad.php?t=25877

    It describes my lower control arm bushings but doesn't talk about my T/C arm bushings. You can see in the picture the parts in question. From what I read in the above thread the control arm bushings are worth keeping to help with camber adjustment. As for the T/C bushings, I was planning on going stock with the rubber replacements for these.

    My questions are as follows:

    I did not make note of the offset on the control arm bushings when I removed them from the crossmember. How do I set them initially during install and how do I adjust them once the car is on the ground? Do I loosen the nuts and give them a 1/6th turn on each side until I get the camber correct?

    I am assuming the large Hex part of the bushing goes towards the firewall based on the fact that standard bushings have the offset towards the rear. Is this a correct assumption?

    The Tension Control Arm bushings look cool but I want to get back to stock where visible. Do these really offer that great of an improvement over stock?

    Pictures below.

    Thanks in advance,

    John

    You are correct in that the hex end goes toward the rear. I have these on hls30-30855, as well as the rear ones as she is lowered. This helps correct the excessive camber when lowered.

    I cannot state what excessive camber would be. Maybe I should have stated the offset bushings allow for adjusting the camber, which when a Z is lowered can be too much negative camber (or more than one would desire). If I recall correctly FAR Performance set mine at 3/4 degree negative on the rear (this was done in 1973).

    the TC rod cup/ball bushings are supposed to offer nice range of motion, I plan on running them until I spring for adjustable tension rods.

    Wish I had this link yesterday. I put the front cupped washers on backwards.

    Looks like I will be spending another 3 hours in the garage today....

    At least you caught it before anything happened. I don't like doing things twice either but it's better to catch mistakes early
