I’ll take them off your hands for a cheeky £150
But seriously they are pretty bad when the roads are slightly moist. I almost stacked it on a roundabout as the back tyre lost grip.
My 530d came on PZero's and I also found them to be bizarrely lacking in the most normal of situations - pulling away from junctions etc. I've swapped the rears to Eagle F1 A3's now and its far better.
There is a new model PZero now which seems to be far better. Helpfully its almost impossible to tell them apart and they both have the same name.
