C2 Give me some more Positive Camber

[Joe Gushen]

66 427 Convertible

I Have a need for some more positive camber. My shims are maxed out and I don't want to bend my frame. I was told there were some old school tricks and parts that would fix this problem.

What is it that I need to do?

What parts do I need?

Where can I get them?

As Always Thanks in advance for all your help.

The only ways that I know of to do this is to:

1) "roll" the frame (i.e. bend it back to original spec which you want to avoid)

2) install special "offset" upper a-arm shafts. I don't know where to get these, but they must be out there. The 63-82 Corvette upper shafts are the same as 65-70 passenger car. So, if you can't find the special shafts in the Corvette marketplace, perhaps you'll be able to find them in the passenger car marketplace.

Joe,
The guys on the camaro/chevelle website call out for a Moog K5250 offset A arm shaft which apparently is getting harder to obtain.

Camaro and Chevelle use a different upper shaft than Corvette. However, if Moog does offer one for those applications, it's likley they offer one for the Corvette/passenger car applications, as well. So, a Moog dealer might be just the place to try.

Zero to -1 camber on the front end it actually advantageous to handling. What are your current front end alignment settings - camber and caster.

Addendum

Joe and John------

K6104 is the Moog part number for the "offset" upper a-arm shafts for 63-82 Corvettes. In fact, this may be the only part that's available from Moog for 63-82 Corvette applications (i.e. for folks that have a camber adjustment problem, or not). These should be orderable through NAPA as well as, I'm sure, others.

These shafts are not for folks concerned about exact, original configuration, though. They do have a different and, presumably, discernably different configuration than original shafts. However, if one has a camber adjustment problem and one is more concerned about function than form, these might be the "hot ticket".

Re: C2 Give me some more Positive Camber

Am I missing something? He said he was maxed-out on shims and needed more positive camber. Seems to me he needs to remove some shims. Shims added more -, shims removed more + !

WHAT?

Re: C2 Give me some more Positive Camber

Whoops, got it backwards. It's pretty early out here on the West Coast.

Adding shims increases camber in the negative direction.

The thread originator should give the current settings and shim stack.

Re: C2 Give me some more Positive Camber

Same question but concerning castor. If you max out the bolt,what then ?

Thanks

Re: C2 Give me some more Positive Camber

Moving a shim from the front to the rear will increase caster with little effect on camber. Once the rear stud is packed, you can just remove shims from the front to get more caster, but camber will increase in the positive direction.

You can visualize this by taking a drafting triangle or just drawing a triangle on paper, One corner is the ball joint, the line connecting the other two is the pivot axis. As you move the pivots laterally together you move the ball joint laterally, which alters camber. If you move one end of the pivot axis out and the other in, you move the ball joint longitudinally, which alters caster.

Re: C2 Give me some more Positive Camber

I already removed all the shims from the front bolt (it needed removal on both sides). The car is not completly assembled. Could this be the problem ?

I was thinking chassis, but after measuring it seemed fine...

Thanks
