The Audi R8 GT Spyder chassis is in keeping with the classic construction from motorsport, with aluminum double wishbones serving as the suspension. The hydraulic rack-and-pinion power steering provides a sensitive, highly responsive connection to the road and is direct, with a steering ratio of 16.3:1. The tuning, optimized for the racing circuit, lowers the body by approximately 10 millimeters (0.39 in). Higher camber rates at all wheels make the handling more agile than on the production model.
The 19-inch forged wheels have different rim widths, with 8.5 J x 19 format up front and 11 J x 19 at the rear. The tires are 235/35 and 295/30, respectively.
A tire pressure indicator is standard. Audi will install 305/30 tires at the rear on request. Individualists can opt for other wheel designs, and for racing enthusiasts, Sport Cup tires are available.
The standard package for the Audi R8 GT Spyder includes the internally ventilated and drilled carbon-fiber ceramic brake disks. Altogether they weigh around nine kilograms (19.84 lb) less than the steel disks from the standard version, with the same format. In terms of stability and service life, they deliver equally convincing results.
The disks measure 380 millimeters (14.96 in) up front and 356 millimeters (14.02 in) at the rear. Elastic elements connect the friction rings with the stainless steel caps. The lightweight aluminum brake calipers – with six pistons up front – are anodized red and bear “Audi ceramic” badges.
The ESP stabilization program in the R8 GT Spyder is specially tuned. The driver can select a sport mode that allows easily controlled oversteer when accelerating out of a corner. The system can be deactivated entirely for a trip to the race track. The Audi R8 GT Spyder achieves extremely high lateral acceleration and is dynamic, precise and stable in its handling.
