Decent tyres mate, repalced the Eagle NCT5 and the Excellence, The F1 repalcement is the Eagle F1 Asymmetric.
The main focus on the Efficent Grip is long lasting, low rolling resistance, less noise pollution an all round greener tyre.
The Eagle F1 Asymmetric is a tyre worth trying, Working for Goodyear we get to go on days out testing different tyres on Different vehicles and they score pretty well
Had them on my golf with 200bhp and over 300 lb/ft, hard to break traction with them on too.
