Zev Barnett/Avalon Motorsport
Zev's 2002 S4 represents the most significant points leap from a previous contestant. Avalon Motorsports, Zev's Colorado-based tuning shop, spent significant time and effort on the development of this Audi and it shows. The car made it through the road course at a blistering pace, garnering the third fastest time of the day. Considering the car was producing significantly less horsepower than the next contestant, this spoke volumes about proper chassis setup.
Although still running the original turbochargers, Zev dipped into the RS4 parts bin for injectors, fuel pump and intercoolers. Avalon Motorsports intercooler misters were a welcome addition in the desert heat, which was thankfully only in the low 90s. The engine also includes MTM thick head gaskets, aluminum flywheel, Autospeed trans-stabilizer bar and an exhaust comprised of UUC and Autospeed components.
The Audi is suspended via H&R Ultra coilovers, augmented with Intrax swaybars. 3R Automotive aligned it to Champion's specs before corner balancing it. The result was the best steering feel of any B5 car we've driven.
Avalon's S4 wears an RS4 nose and an M3 rear spoiler. The body also includes Valeo Euro-headlamp housings, a Fiber Images carbon-fiber hood, and Hagus sport mirrors. The interior was kitted out with Topspin harnesses, Defi-boost/timer system, and a Halon fire extinguisher. Zev had a rocking A/V system installed including JL Audi subs, MB Quart drivers, Rockford Fosgate amps and the factory's RS4 NavSat Plus system with an in-dash Icon TV/DVD player.
Dan Barnes loved this car, and with good reason: "It sounds perfect, pulls hard and makes great power. It inspires awesome confidence at speed." Coming from a hard-to-please guy like Barnes, that's means it's damn good.
