Had my Michelin Pilot Alpin winter tyres swapped over to 4 brand new Michelin Pilot Sport 4's.
They are a revelation. I've only done 10 miles on them so far but the reduced road noise, the ride comfort, the response and the grip are exceptional! I'm scrubbing them in for a couple of hundred miles before driving hard on them, but half throttle acceleration is smooth and effortless where the Bridgestones would have been spinning up and tramping.
If I ever buy a car with Bridgestones as standard, I'll be budgeting to swap them before I collect the car.
Over the coming weeks I'll also be fitting new discs and pads all round (Brembo items), and giving it it's spring detail. I'll be hoping to refinish the hubs and calipers too if I can find the time.
