twitch

I've recently started to get a slight twitch back through the pedal on the 129, almost like a burp or hiccup from the hydraulic system. It's usually under light or moderate braking, but doesn't happen every time. The brakes seem to work perfectly well, although I notice the braking force...

HI Chaps, today i noticed if i am turning left at speed (constant and accelerating) the back end tends to twitch and/or step out? I have new tyres, although budget on 19" C63 copy rims (already on the car when i bought it) with BC racing shocks with the standard springs. Any well know...
