also I want to clarify does adding shims increase negative camber?
- looking for a fast easy answer of if I want to just a slight amount of negative camber since it seems I am at 0 now, to go to 2 degrees negative how many mm generally will it take- trying to just buy a few shims not a bunch! currently does appear that the right and left a same, my initial check was 0 and 0.

So adding shims will DECREASE neg camber - make it more positive. Camber on the rear is very dependent on ride height - if you have aftermarket springs (or tired springs for that matter), that may need addressing first: a "higher than stock" ride height will tend towards positive camber, a low ride height, more negative. Hence with the more aggressive, lower rear height settings on 914's you have to start bulking up on the shims, or taking more drastic measures to offset the neg camber you got as a result.
Rake also has a minor contribution. Adjustable height shocks, or coil-overs, allow you to adjust ride height to varying degrees of granularity. As ever, the excellent article here: http://www.914world.com/bbs2/index.php?act...t&id=363723 ...is a great starting point to understand whats going on. Wealth of suspension expertise to tap on the forum as well. - Tony |
