I had RE050A's on an S3 and they weren't as good as the F1's. Much preferred the F1's wet and dry.
The Avon ZZ3's on the Leon were good, and lasted 20k front, 40k rear. Replaced fronts with Pirelli Rosso which are crap as far as I'm concerned.
Had an Octy II VRS TFSi until about 6 weeks ago and ran Mich Sport Pilot Exalto and they were alright, but the Toyo Proxes T1-R that replaced them changed the car - fantastic. Just gripped and gripped. Now I'm looking for 4 tyres for the Leon and can't get Proxes till April 12th and I'm not sure it will wait as I'm getting very close to the limit. Tempted at the Yoko Parada S2's. Seem good value too but I really set out to get me some Proxes......... decisions, decisions!!
