The longer new carbon body, that giant fixed rear wing, new front splitter and side sills plus the giant new diffuser make up the aero mods. It’s all to do with downforce of course; though again, no figures on that for the moment, just the assertion that it’s “substantially more” than the standard 570S.
Making the most of that downforce are some significant changes under the skin, not least the addition of the forged aluminium double-wishbone suspension and lightweight braking system from the McLaren 720S. The engine mounts are firmed up over the stock 570S, and the steering, braking and throttle responses quickened. All 600LTs roll on Pirelli Trofeo R tyres.
And inside? Lots of Alcantara (it’s lighter than leather) and, as standard fare, the carbon seats from the P1. Pay more and you can have the ultra lightweight seats from the McLaren Senna. You will need those – plus the MSO options of carbon roof, cantrails and front fenders – if you want the car to hit its target weight.
