The Pilot Sport 4S is indeed seen as a long term substitute for the Pilot Super Sport and it sits nicely between the Pilot Sport Cup 2, Michelin's road legal track focused tyre and the more versatile, mass market sports tyre, the Pilot Sport 4. The Ultra-reactive tread pattern design, adapts continuously to the road, for optimised footprint on the surface. Giving the driver a high level of reactivity and improved feeling. The Pilot Sport 4S also features 'Dynamic Response' technology; a hybrid belt of aramid and nylon which ensures optimum transmission of steering instructions onto the road. The exceptional dry grip and improved wet braking are the result of Bi-Compound technology (e.g. more than one compound on the tread) featuring a novel hybrid elastomer for dry grip and a new mix of compound with specific functional elastomers and silica for excellent WET grip and braking.
