North American aftermarket specialist STaSIS Engineering has released a new performance package for the Audi S5 Cabriolet in the UK. The STaSIS Engineering S5 Cabriolet Challenge Edition features an upgrade kit that includes an engine tune, Ohlins performance suspension, monobloc brake calipers and a limited-slip differential.
The 3.0-liter supercharged V6 engine develops 410 horsepower, an increase of 77 horsepower compared to the factory S5 Cabriolet. Torque is also up on the S5 Cabriolet Challenge Edition, from 344 lb-ft (465 Nm) to 370 lb-ft (500 Nm). The power boost is due to the ECU remap and the fitting of a high performance exhaust system.
Naturally, the car's performance numbers are also improved, with STaSIS' S5 Cabriolet hitting 60 mph (98 km/h) from a standing start in 4.3 seconds, 0.7 seconds faster than the standard model. In order to improve braking distances, the S5 convertible is fitted with Alcon 6-piston monobloc calipers, 370 mm two-piece front discs, high performance pads and braided stainless steel brake lines.
To improve handling, the suspension uses Ohlins SL dampers with two settings (for ride comfort and better response) and adjustable ride height. The package is rounded off by 20-inch ultra-lightweight forged aluminum wheels shod in high performance low profile tires.
STaSIS performance components are available separately or as a package through APS of Brackley and STaSIS dealers across the UK.
