Correcting rear camber H&R coilovers
#17
Mike A: Didn't mean to bore you with the kinematics 101. But, hey... if you understand the Porsche IRS then I've got a Q for you: I spent some time with the shocks out, a toe-plate attached to the hub and string-line to measure the rear toe change with bump/compression. On other cars, the setup was easy to understand and you'd usually just need to correct the toe change at +/- 2" travel to as close to zero as you can get it by shimming the toe-rod attachment points. On the Porsche, it seems different. The two upper links oppose fore and aft movement/rotation of the spindle as well as decamber with compression. However, they attach to the upper hub in an asymmetrical fashion. It's almost as if Porsche designed in some sort of rear steering(?). Is that so? If so, has anyone shared specific numbers of what to try to achieve when correcting rear suspension travel on a lowered car?

Weird they have them on their website http://meganracing.com/mrs-pc-0470.html
Fwiw , I couldn't be happier with the tarrett ones , very well made and more importantly they are a very effective solution .
