Simply put, the SRT-4 Extreme is the award-winning Dodge SRT-4 taken to its practical limits. Capturing and celebrating the enthusiasm that defines Chrysler Group’s Performance Vehicle Operations (PVO), it is the test bed – the prototype – for the development of current and future Mopar Performance Parts. Extensive use of lightweight carbon fiber and composite parts has reduced the weight of the Dodge SRT-4 dramatically – by an estimated 500 pounds compared to the production SRT-4.

As the ultimate sport compact “tuner” vehicle, the SRT-4 Extreme features a prototype edition of a potential future Mopar Performance turbo upgrade kit, a dramatically lowered ride height provided by a Mopar Stage 3 coilover suspension kit, and an impressive list of brand name performance parts -- including a Mopar short-throw shifter, a Mopar blow-off valve kit, a Borla catalyst-delete resonator, Michelin Pilot Sport Cup race tires, a brake kit from StopTech, SSR semi-solid forged wheels, a six-point harness from TeamTech, Recaro race seats and a Moroso detachable steering wheel -- that make this car the performance enthusiast’s dream.

There’s no mistaking the SRT-4 Extreme. Equipped with a subtle body kit, it features a subtle bright silver metallic exterior, with a lightweight carbon fiber hood, deck lid, front and rear fascias and door assemblies. The intentionally minimal interior -- making the car suitable for potential Sports Car Club of America (SCCA) or private racing venues – includes competition seats and harnesses and a welded-in roll cage.

Mopar Performance Stage 1 Turbo Upgrade Kit

Mopar Performance has introduced a whiplash-inducing Stage 1 turbo upgrade kit. This kit pushes the power and performance of the 2.4-liter turbocharged engine in the 2003 Dodge SRT-4 to 240 horsepower and 260 lb.-ft. of torque, and the 2003 Chrysler PT Turbo to 235 horsepower and 260 lb.-ft. of torque.

The kit consists of four fuel injectors, which produce a 10 percent greater flow rate than stock injectors, and one Mopar Performance powertrain control module (PCM). The PCM has been calibrated for increased wide-open throttle and part-throttle boost, more aggressive exhaust note during deceleration, improved turbo response, enhanced first-gear boost schedule for a higher performance launch and a boost-hold feature during wide-open throttle shifts.

Manufacturer’s suggested retail price (MSRP) for the Stage 1 turbo upgrade kit for the 2003 Dodge SRT-4 and Chrysler PT Turbo manual (P5007862/P5007943) is $399. MSRP for the Stage 1 turbo upgrade kit for the 2003 Chrysler PT Turbo automatic (P5007944) is $429.

Stage 1 turbo upgrade kits for the 2004 Dodge SRT-4 (P4510592; $399), the 2004 PT Turbo manual (P4510606; $399) and 2004 PT automatic (P4510597; $429) are also available. Stage 1 kits for the 2004 models result in the same performance ratings as the 2003 models: 240 horsepower and 260 lb.-ft. of torque.

Mopar Performance Turbo Blow-Off Valve Conversion Kit

The new Mopar Performance turbo blow-off valve kit reduces intake air charge temperature by venting the hot compressed air to the atmosphere and not re-circulating it into the intake system. The blow-off valve kit is a must-have accessory that enhances the distinctive turbo sound of the Dodge SRT-4 and Chrysler PT Turbo. The kit (P4510548) is now available for the 2003 and 2004 Dodge SRT-4.

Mopar Performance Limited-Slip Differential (LSD)

Mopar’s limited-slip differential is another high-quality component that helps make the 2003 Dodge SRT-4 even quicker. The Quaife automatic torque-biasing (ATB) differential is available exclusively from Mopar. The unique design improves handling and steering, and powers both drive wheels under nearly all conditions. It senses which wheel has better grip and biases the power to that wheel. It does this smoothly and continuously, and without ever completely removing power from the other wheel.

Mopar Coilover Suspension Kits

The Mopar coilover suspension kits are a result of a relationship between Mopar Performance and KW Suspensions. Utilizing DaimlerChrysler specifications to ensure optimum performance, the kits feature new stainless steel INOX technology exclusive to Mopar Performance. The Mopar coilover kits’ thread design and aluminum spring perches allow Dodge SRT-4 owners to easily adjust vehicle height. Additionally, the special thread shape and specific properties of the polished suspension struts ensure that virtually no corrosion occurs – even after years of the strongest weather influences.

The basic Stage 1 suspension components include a set of higher rate drop springs (P4510458) that utilize production Dodge SRT-4 dampers and an anti-sway bar kit. Both components will be available early next year.

The Stage 2 Mopar coilover suspension kit is an introductory coilover system – height adjustable only. Its fixed-valve dampers are calibrated to provide a balance between “comfortable” road feel and sporty driving.

Stage 3 Mopar coilover suspension kits are height- and rebound-adjustable, and include up to 50 percent more adjustability than Stage 2 settings. This allows the driver to tune the SRT-4 suspension to even greater degrees, from a “comfortable” ride, to sporty, to stiff — tailoring road handling to the driver’s specific needs.

Mopar Cat-Back Exhaust System

Mopar Performance cat-back exhaust systems feature T304 stainless steel construction (aircraft quality), with mandrel-bent tubing, stainless band clamps and polished tips. These free-flow systems provide horsepower and torque gains, improved fuel economy and a deeper exhaust note.

Mopar Performance Short-Throw Shifter

The Mopar Performance short-throw shifter is a direct, bolt-on, self-contained unit. It offers a dramatic improvement in shifting performance due in large part to reduced shifter travel or "shifter throw." In performance driving scenarios, the additional seconds -- or fractions of a second -- a factory-equipped shifter takes to go from one gear to another may result in slower lap times. The Mopar short-throw shifter gives the racer a competitive advantage.

Mopar Performance Gauges and Pods

Mopar Performance has developed a full line of gauges to fit the needs of the street-performance enthusiast. These gauges are available only through Mopar and feature an aluminum bezel and four different face styles. The styles include silver with the SRT logo, silver with the Mopar logo, carbon fiber with the Mopar logo and white with the Mopar logo. The types of gauges available are boost, nitrous, voltmeter, exhaust gas temperature, oil pressure, fuel pressure, air-fuel ratio, water temperature, a 2-inch tachometer and a 5-inch tachometer. Mopar also offers single or dual gauge pods that mount on the driver's side "A" pillar. MSRP for Mopar Performance gauges range from $45.73 for a 2 1/16-inch voltmeter to $318.26 for a 5-inch tachometer. Pods for the Dodge SRT-4 range from $29.50 for single pods to $37.80 for dual pods (all pods are for 2 1/16-inch gauges).

Mopar Katzkin Leather Interior Program

Katzkin Leather Interiors, Inc., has transformed the interiors of more than 500,000 vehicles since 1983. Katzkin’s leather interiors are produced using the latest in high-tech computer aided design. Thanks to Mopar’s unique relationship with Katzkin, Chrysler, Jeep and Dodge dealers can create custom leather interiors to suit their customers’ wants and needs.

More To Come From Mopar Performance Parts

In the months to come, Mopar will announce the release of a wide variety of new performance parts for the Dodge SRT-4. Included are a Stage 2 turbo upgrade kit, a Stage 3 turbo upgrade kit (for the SRT-4 only), and performance upgrade clutches, designed for increased torque capacity and durability.
