GMG has worked with Eibach the world leader in spring and sway bar development design and manufacturing to develop the GMG World Challenge sport sway bar kit for the 997TT. A GMG exclusive design which features sway bars that are 3 way adjustable front and 3 way adjustable rear.
The rear sport sway bars offers a torsional stiffness increase of 30,45 and 60% while the front front sway bar offers an increase of 15/25 and 35% over the factory bar. All sway bar kits feature urethane bushings and offer the highest torsional stiffness on the market today. Thousands of road miles, countless laps at the track have yielded a sway bar package that minimizes the under steer that these cars exhibit when being driven hard and offers the driver neutral handling while minimizing body roll.

The GMG WC Sport Sway bar kit is designed to work with the factory drop links and does not require the use of a rod end style drop link to clear the front axles which ensures that you dont have unwanted noise and popping due to the use of in-expensive rod ends used by most competitors. The highest quality materials and most stringent manufacturing process have been utilized in the manufacturing of our sway bar kits. Dont be fooled by other companies offering no name brand products which are made with inferior materials and cost less. Demand the best when it comes to your suspension for Porsche.
GMG WC Sport Sway bar kit can be used with any combination of suspension packages ranging from stock shocks and springs, GMG WC Sport Lowering Springs, Bilstien PSS damper kits to full race coil over dampers such as Moton, JRZ and Ohlins.

We spent over two years of development work with our Speed World Challenge GT WC- 996 GT3 Cup cars and Eibach to develop the ultimate bolt on anti-roll bar upgrade for your 996GT3 and 996GT3 RS and 996GT3 CUP( can also be used on the 992C2). GMG Is proud to be the first tuner world wide to offer a complete bolt on anti-roll bar upgrade the GT3 and RS. Racing in the Speed GT series and running on a DOT R- Compound tire has allowed us to use the data and knowledge gained over the years and apply it to a street/track bolt on anti roll bar kit that improves the handling of your car, without costing thousands of dollars like the bladed racing versions that we run on our race cup cars.

Designed, developed and tested on our 996 GT3 WC street car, and made for GMG by Eibach, the World Challenge anti-roll bar features front and rear hollow tube anti-roll bars that are 5 way front and 4 way rear adjustable. The rear bar offers an increase in stiffness from 20 to 80 percent over the stock bar and the front bar offers an increase of 10-50 percent increase over the stock front sway bar. Complimented by urethane bushings these bars are a must have for anyone who is tracking their GT3 / RS or racing the 996GT3 CUP and simply wants to reduce the "push" that these cars exhibit during spirited driving and track use.

The GMG WC anti-roll bar kit is sold as a complete kit and is a true bolt on upgrade that requires no modifications to your vehicle and works with the standard sway bar drop links and dampers or any after market damper such as Moton , JRZ or Ohlins

GMG Introduces the first and only 3 way adjustable front and rear sway bar kit on the market today. Designed tested in proven over 1 year of development GMG World Challenge sway bar kit features a hollow bar design, 3 way adjustment for both front and rear bars, work with factory drop links and feature urethane bushings. No need for curved or solid rod end style links which will only wear out in time and make noise. Direct replacement front and rear sway bars are the ultimate upgrade for your street or track 996TT. These sway bars offer adjustments and stiffness increase over the stock front and rear bars (Rear 35/50/65 and Front 20/35/50) Made by Eibach from the highest quality materials and built to TUV standards for years proven reliability.

Will work with stock shocks and springs, lowering springs, PSS 9 and 10, KW , Moton, JRZ, Ohlins damper sets.

Clubsport is getting more and more famous world-wide. Therefore, KW has decided to develop a new product line – KW Clubsport. This new product line is distinguished by motorsport applications for race track and road use with ideal performance.

Nürburgring Nordschleife is the most popular race track for using our KW Clubsport suspension kits. High performance sports cars, modified saloons as well as classical sport compact cars are tuned in weight, engine and wheels for their use on several race tracks. These improvements are made for a better handling on track sport events, race taxi drives, visitor drives and equability tests particularly on the Nürburgring Nordschleife. Due to these modifications of the car some parameters are changing. Therefore, the road setups are no longer ideal for the performance of the car. For this use we offer special clubsport kits which have been adapted to the changed requirements by changing spring and shock setup as well as the installation of racing top mounts.

• Performance setup for the racetrack
• Dampers in compression and rebound forces independently adjustable
• Use of high performance linear race springs
• Additional available with racing top mounts
• TÜV approval possible depending on the specification

The new Variant 3 is state-of-the-art technology for the skilled and experienced driver. The separate and independent compression and rebound damping options allow a truly individual driving set-up. These unique systems with the 3 individually adjustable components, allows for adjustment of the compression of the damper in the low-speed range, while the highspeed set-up, so decisive for driving comfort, has been preset by our engineers

• Independently adjustable damping technology -rebound and compression damping
• "inox-line" stainless steel technology
• Individual height adjustment
• German TUEV-tested adjustment parameters
• High-quality components for long life
• Comprehensive documentation for ease of use
• Infinitely adjustable rebound damping
• 14- level adjustable compression damping
• Unique, independently functioning damping power adjustment

Helping sport cars avoid road clearance difficulties Raises the vehicle up to 45 mm

The HLS provides additional road clearance for lowered vehicles. When expanded, a range of 30mm to 45mm of lift is produced, thereby helping sport cars avoid road clearance difficulties like speed bumps, road constructions etc.

• For vehicles with with little road clearance
• Vehicle specific applications
• Activation of change in height by a small keychain transmitter avoiding the need to run additional wires through the vehicle
• Height changes can be done while the vehicle is moving, up to speeds of 50 mph
• Automatically lowering of the vehicle
• With TÜV certificate
• Rubber bellows protect hydraulic cylinder, thereby providing long term durability

The hydraulic cylinder unit is installed between the spring perch and spring. The pump unit is installed inside or near the spare wheel well. A programmable control unit processing the CAN Bus signal for speed control is also included in the kit.
