Project S4 takes deep breaths

Project S4 (B5 Audi 2.7-litre V6, 30V twin turbo) is steaming along nicely now. We are just about to fit a high-flow K&N air filter, pictured above, (to go with the Milltek sports cat system, Forge blow off valves and Superchips ECU remap stage one engine tune), do a brake upgrade to set it up for fade-free track use, set-up the Bilsteins and go into a bit more detail on this amazing suspension kit, service it properly at Henstead Motorsport and do a few more jobs; like a deep clean with a Karcher pressure washer and some Sonax cleaning products. Follow its progress in detail here, including a test on the Dunlop Sport Maxx TT tyres fitted over Winter: http://www.roadmagazine.co.uk/?page_id=527. Spring is here... it's track day season – yes! The Green Hell and Spa-Francorchamps are calling!
