Just some feedback on my first post I am very pleased with the Proxes car feels a lot more sure footed especially in the wet.The car feels more balanced in the dry but this is probably due more to the removal of the mix in tyres fore and aft.
Car tramlining seems reduced even on the parts of the M3 that have more rutts than a farm yard not much difference in road noise levels.
Fitter checked rears and have lost about 2 mm for 10k miles which is reasonable.
So overall I must say I am impressed.
I sourced them from tyretraders.com who I have used before and seem pretty good.
