Alfa Romeo forum: Brakes Again - 330 ’s and rear brake bias

I've done a few track days since then and not had any problems. Mine moves about a little bit under heavy braking on the road but its never particularly worrying in fact I don't think its any worse than any other 156 I've driven.

I have upgraded to DS2500's in the front, that may have changed things I guess.
