As if the standard 570S wasn't already light, McLaren's engineers have managed to cut a further 55 lbs (25 kg) of fat.

Available right away, the kit will replace the 570S’ standard seats with lighter ones dipped in carbon fiber and with better lateral support. Also part of the diet is the new super-light alloy wheel set backed by the same carbon-ceramic brakes you get with the regular 570S. There’s now Alcantara instead of leather for the steering wheel, dashboard and seats to further cut weight. In total, the coupe from Woking will lose 25 kilograms (55 pounds) with the Track Pack installed, so it’s going to tip the scales at 1,319 kg (2,907 lbs) without any fluids.

As you would imagine, the weight loss is paying dividends in terms of performance. The sprint to 124 mph (200 kph) now takes 9.4 seconds, which is a tenth of a second less than before. As far as top speed is concerned, it has remained the same at 204 mph (328 kph).

But there’s more to the Track Pack than just a weight loss as McLaren is also giving the 570S Coupe a beefier rear wing sitting 12 mm higher than it does on the standard version to generate an extra 29 kg (64 lbs) of downforce at 150 mph (241 kph). It’s exclusive to this optional package, which also brings a Dark Palladium livery from McLaren Special Operations for the roof and a so-called stealth finish for the exhaust tips.

Also part of the deal is the Track Telemetry system carried over from the meaner 675LT and the P1, both of which are no longer available. It gives the driver access to real-time information, like lap times, post-drive analysis, data logs, and comparisons between two drivers.

McLaren is asking £16,500 (about $20,570 / €19,450) for the optional Track Pack and mentions it will kick off deliveries at the beginning of 2017.
