I have also read the forum post u quoted. As i understand it the 6 degree beam wont change ur rollcenter. Just get rid of some of your bumpsteer. U are probably better than me on the geometry but as I understand it this is how u measure your rollcenter on a semi-trailing rear suspension
That means u only move ur rollcenter forward since ur not changing the pivot axle angle up/down. Or am I totaly retarded?

Thats why I wanted to move mine up abit.
As for my arb it is the front 29.3mm one. Will be put togheter with my 3dr hubs along with adjustable tca:s so the width problem wont be any problem I hope.
Caddyshack:
Is it a 1 way, 1.5 way or 2 way lsd? As said it is probably ur lsd ur feeling when u make a tight turn.
Here's a good video explaining it if u dont know.
Edit: Sorry for making a mess of your thread Marc
