It'll be for a trackdaycar, so the stiffer the better.
Actually atmo the rear is fully polybushed (besides diff hanger)
Got myself a set of toe-in shims of R&B. And got 2 camber adjusting shims fabricated by a m8 of mine to reduce camber to -1 (is now -2, and -1 is recommend for trackuse?)
These still however need to be fitted soon before next trackday.

Besides the above geometry alterations, I'd like to stiffen up the rear some more. When pulling out of corners i can feel the rear swing/wobble/sway/ or however i should discribe it

So adding a solid diff mount would improve stability in the rear end?
Anyone selling the solid kits (including solid mounts) in the uk?
About those solid mounts, there the same as all my powerflex but then out of steel/alu? pics anyone?

lol, too many questions perhaps, but for a newbee in the cos scene all hints/help are greatly appricated

ps. my english isn't that good, so maybe i misunderstand. The beam mounts, they mean all the mounts on the rear beam? or some part of the rear beam?
