Putting power around bends and shooting out from S-bends, akin to a wiggle.

I dunno what I've got then - I get the wiggle in the straights!

Your sub frame bushings have become "softer" over time so the rear will wiggle anytime of putting down power, my car is only three months old and I get the rear to wiggle!

TS135i great write up! (Didn't want to quote the long post). I think I'll grab the FSB and collect a couple suspension parts and install them all at once.

That wiggle can also be attributed to the rear suspension components. The M3 guide rods and toe links vastly improve "wheel hop" in straight line acceleration and the "wiggle" you experience around turns. It is a never-ending process of improvement.
