APS, the UK importer of the Swiss tuning brand Sportec, has turned to North American-based VW specialist, STaSIS Engineering, for its newest project concerning the latest generation of the Audi S4. The STaSIS Signature S4 is available in two flavors, the Touring and the Challenge editions, with both featuring an engine kit that boosts the 3.0-liter supercharged V6's output from 333 bhp and 344 lb-ft of torque to a more dazzling 410 bhp and 370 lb-ft.
The base Touring Edition package also includes suspension, brake and exhaust system upgrades as well as 19- or 20-inch alloy wheels, while the Challenge Edition comes with more hardcore components such as larger brakes with 6-piston callipers and ultra-lightweight forged aluminum wheels.
The STaSIS Signature S4 packages are available now from APS of Brackley, with prices starting at £12,500 including VAT (20%) and installation.
