STaSIS Debuts S4 Sedan and S5 Cabriolet

October 28, 2010

Performance-Enhanced Supercharged Trio to Debut at SEMA 2010

STaSIS will debut its new 410-hp Signature Series S5 cabriolet at the 2010 Specialty Equipment Market Association (SEMA) show on November 2 through 5 in Las Vegas, Nevada. This sport convertible will be showcased alongside the class-leading STaSIS Signature Series S4, with 410 hp and 370 lb-ft of torque.

Both vehicles feature race-derived brake, suspension, and driveline products that deliver nearly 25 percent more power and an extra 26 lb-ft of torque over the factory models, balancing significant performance gains with comfort and reliability. Equipped with a race-derived suspension, 390-mm, 2-piece brake rotors, lightweight forged 20” wheels, and an aggressive exhaust, these vehicles have a power presence that remains nimble and responsive.

The 4-door, 4-wheel-drive, 410-hp Signature Series S4 runs with world-class sports sedans such as the BMW M3, Cadillac CTS-V and Lexus IS F in both speed and handling, all at a reasonable price tag. The Signature Series S5 Cabriolet boasts a convertible top and the performance of the STaSIS S4, delivering a truly exhilarating driving experience.

STaSIS takes a holistic design approach by engineering all systems to perform together harmoniously, providing driving enthusiasts racecar-inspired performance without compromising everyday driving comfort. This balance is built into every car we design, from the 710-hp R8 V10 Spyder, to the STaSIS version of the popular Audi A4, to the STaSIS TT, S5, S4, A6, A5, Q5 and A3 models. Available from over 50 dealerships nationwide, all STaSIS Signature Series products are covered by a 4-year/50,000-mile warranty that runs concurrently with the factory warranty.

STaSIS Engine and Exhaust Modifications

 

STaSIS boosts the Audi 3.0-L supercharged engine from 333 hp and 344 lb-ft of torque to 410 hp and 370 lb-ft of torque by tuning the engine software and replacing the factory exhaust with a STaSIS free-flow stainless exhaust.

STaSIS engineered a lightweight, free-flowing, T304 stainless steel exhaust system that works in harmony with the engine tuning software. The exhaust uses the first true cross flow pulse scavenging technology applied to the 3.0 supercharged engine and independently provides an additional 8 hp. The mufflers incorporate reflective and passive technologies to optimize sound and minimize back pressure. The sound is noticeably deeper and more aggressive and can be personalized with customer-tunable resonators.

Wheels
Signature Series S4 and S5 Cabriolets are equipped with either 20” lightweight cast wheels or 20” ultra-lightweight forged wheels. Both wheel styles are DOT and JWL certified and help to improve handling, acceleration and stopping.

Wheels are equipped with Yokohama S-Drive high performance tires or Yokohama Advan Sport Extreme Performance tires. Combined with the race-inspired suspension and lighter weight brakes, the Signature Series S4 and S5 are both capable of 1.0 G cornering acceleration

Braking
The STaSIS braking system uses lightweight, 2-piece 370-mm (390-mm optional) rotors and calipers that are direct descendents from the highest levels of motorsport. The rotors have large air gaps, directional aerofoils and a custom iron alloy that help to quickly extract heat generated when stopping. Bolted to an aluminum hat via a floating pin design, these rotors allow for stop after stop without overheating or warping due to heat stress.

The factory two-piece sliding calipers are replaced by 6-piston monobloc aluminum calipers that are 50% lighter. The pistons use high-resilience seals for quick piston activation and retraction, providing the driver with a firm pedal feel that is linear in action across all temperature ranges.

The system is completed with high-performance brake pads and stainless steel lines. Stepping on the brake pedal delivers an aggressive initial bite that will not change as brake temperature increases. This gives the driver the confidence to dive into every turn without worry.

Reducing the weight at each front wheel by nearly 13 pounds enables quicker steering wheel inputs and requires less work for the suspension, which in turn improves handling.

Suspension
The Signature Series S4 and S5 Cabriolet combine lightweight dampers and high rate springs with an uprated anti-roll bar kit. The motorsports-derived dampers utilize STaSIS double-digressive valving to produce racecar control and street car comfort. Our success in balancing the conflicting goals of a more aggressive stance, improved handling and ride comfort is part of every Signature Series car we produce.

STaSIS Warranty
STaSIS products purchased and installed by a certified STaSIS dealer are covered by a 4-year/50,000-mile warranty that runs concurrently with the standard factory warranty. The STaSIS warranty is the only factory-level warranty in the industry.
