I understand with the modded rear beams that camber and toe can be adjusted with use of rose joints, but does the 6 degree modification deal with camber increasing as the rear end squats? (Sorry cant seem to find an answer on the search query).

Therefore is there less chance of wheel spin due to tyres staying more square to the road surface or am I wrong in thinking this?

yes, as the wheel forms far less of an arc as it travells, exactly the same way it combats bump steer, as as the wheel moved uowards on the old beam, it gives a huge change in toe and camber.

Not having seen one of these beams, I would be interested how much change there is.
Obvioulsy ANY semi trailing arm as opposed to trailing arm will induce camber changes, but would be interested yo read of owners(modded beams) views.

Basically, the pick up points are moved, so that the movement of the trailing arm is different to standard, you can kind of tell from the picture, that when the arms pivot, they move upwards rather than inwards...if you get me

the arc of the standard beam is to put the wheel inwards and forwards so not only does it change the camber but also the toe in

Didn't Mike_R have some measurements of the changes on his Moonstone Blue Sapphire thread - if it's still on here that is - used to be in one of the other forums I think

That's the same arrangement used on the old rally cossie I beleive, saw it on cosworth.hu.
How much do they charge for this ?
