How do you move the A-arm How much and which way. Don't really understand what it does but know that is needs doing. Any help would be never forgotten.

Some of the guys on this forum have just been dealing with that subject.In this fourm,click on show topics from the last 60 days,instead of the last 45 days. On the question "Help me please,A-arm tower locations" r19v tells you how. Also read the answers on the question "spring adjusters" as it is sometimes a related job. If after reading,you still have any questions,let me know,always glad to help.....also,you need to read awkwardjeff's answer about bumpsteer...

I'm gonna put this question here since the other upper tower relocation post is sooo far back. Anyways, are you guys able to do this within your rules or are you simply just getting by with it? I would love to move mine but am scared to death that the tech guys will find it and holler. I mean it ain't something that you just unbolt and bolt the legal part back on ya know. Is a slightly repostioned tower not real hard to spot or something?

I dont know your rules but you could torch off the weld on the top a-arm mounts ,have the spring out, put a jack under lower a-frame , set ride hight, use a caster-camber gauge and put that where you want it(make sure to leave some adjustment in the two upper a-arm bolts) and reweld the top mount back on. it should look close to stock , if posible paint the frame. This is on a gm car. I dont know about any others ,at my track they dont check that. I dont think they can get the factory dimentions.

Snowman, I went back myself and read the post you talked about......that's good information.....the only thing I would like to add is by moving them to the left and back you ONLY adjust caster/camber settings.

I like to rotate the mount to adjust caster gain.........the re-drill to lower the front of the top A-frame is needed .....to keep from unloading the rear tires when applying the brakes......2 degrees is correct.....

I will also say, that instead of moving the mount to the left a guy can build off-set bushing for the lower A-frame this will accomplish the same things as moving the upper mount........and some guys run a left side upper on both sides of the car to get enough caster without cutting off the mount.

and if a person decides to cut off the mount and relocate it.......use a cut-off wheel for you surface grinder..these wheels are about .035 thick...the sell them at welding supply places.....about $3 a wheel.......that's a little expensive but with 2 wheels you can cut off both mounts in about 20 minutes............and do a nice job cuting them off......to reweld them back on start welding then let go of the trigger, cut the wire that is stuck in the puddle, and repeat this over and over.....we will end up with the same UGLY weld you get from the factory.........

Lol, I don't have to worry about getting an ugly weld... I'm a natural at that.
