Mine's got Bridgestones on atm, the RE050a's.. Yeah... Never rated them on any other car, maybe thats why the back end likes to work the ESP system so much.. My other recent cars have all run Uniroyal Rainsport 3's, I really rate these tyres, especially in the wet! They are soft, so I wouldn't expect them to last as long as MPSS and other expensive tyres.. Interesting to see at least one person uses them on their Z and likes them :-)
