JCR takes the only open-topped 911 product to hail from Porsche’s GT department and applies some motorsport thinking, to tremendous effect.
The last 991 built was one of the 1,948 Speedsters, which makes the open car significant for Porsche as well as the GT department. As such most of them are secreted away in collections, untouched, undriven with mileages kept low with an eye on future values.
Fitted here with Michelin Cup 2 R tyres, in 245/35 ZR20 front and 305/30 ZR20s at the rear, the brakes are changed for Surface Transforms ceramic discs, with RSC1 Pagid pads; Cocker says this setup runs cooler, bites better and delivers smoother modulation on both application and release. Those Surface Transforms discs can be re-finished as many as four times too, which is an enormous cost benefit if you’re tracking them, while they’re also slightly lighter than the PCCB disc. Cocker’s working on some titanium bells to replace the Surface Transforms stock items, which he suggests will be 50 per cent lighter again, and offer greater cooling.
Surface Transforms plc (LON:SCE) are experts in the development and production of carbon-ceramic materials and the UK’s only manufacturer of carbon-ceramic brakes for automotive use.
