DDMWorks is proud to offer the Forged Dynalite 4 (FDL-4) Brake upgrade designed exclusively for the Kappa platform (Pontiac Solstice, Saturn Sky and Opel GT). We started out with the simple idea of offering the best performing brake upgrade available for the Kappa that could be fit under the stock wheels. The development of our kit first started by testing several different calipers and brake pads to find out what works best and what didn't work on the unique chassis of the Kappa. Once we knew what we wanted, the research and testing continued until we came up with the perfect combination of stopping power, price and great looks and now offer that as our FDL-4 kit.
Stopping power is the most important part of a brake kit and the FDL-4 caliper is up to the task. To get great stopping power, we replaced the single piston stock caliper with the Forged DynaLite 4 piston Wilwood caliper. The forged dynalite brake calipers from Wilwood have become known as the benchmark in many forms of racing, including road-race, rally and sport driving competition. These calipers offer internal fluid ports which eliminate vulnerable external fluid cross-over tubes creating a more robust caliper for race and street driven cars. The redesigned FDL-4 calipers also benefits from computer generated solid modeling that reduced the weight of the caliper and through careful design was also able to offer overall increase in strength of the body and resistance to deflection under load. Every FDL-4 caliper is made by a stress-flow forging a premium grade aluminum alloy billet into a super strong caliper. This process re-aligns the metal's grain structure within the contour of the caliper making them strong yet light. With these design enhancements the forged dynalites are the strongest calipers in their class.
Once we had the hardware completed we then tested many different brake pad materials on the prototypes to develop the system even more. Our goal was to give great stopping power without making the fronts too aggressive and causing the brake balance to be thrown off and make the vehicle unstable. We were able to carefully match the brake pads in our kit to provide an even brake balance, even if you choose to stay with the stock brake pads in the back. Braking can be improved even more with the optional brake pad upgrade we offer for the rear.
We know that everyone wants their brake kit to look great also, so on the Kappa FDL-4 kit we went with oversized 12.19" diameter rotors, but more importantly increased the thickness to a chunky 1.25" thick. These rotors look great and also offer greatly enhanced thermal capacity from the stock setup. The huge 12.19" rotors are then mated to custom designed billet aluminum hats once again designed in house by DDMWorks to create the lightweight and strong 2 piece rotor for the kit that actually weighs 2.5 pounds less than the stock rotors. The rotors fit under the stock Solstice and Sky wheels and most 18" or larger aftermarket wheels. If you are installing the brake kit on your stock Solstice wheels you will need to install a wheel spacer and our extended lug nuts which can be selected as an option. The Brake kit ships with Hawk HPS pads which work great on the street, we can supply other pad options, give us a call or drop us an email if you think you need something more aggressive.
This kit is the perfect compliment to other wheel, tire, and suspension upgrades that you may have made to your Kappa or as a stand alone modification. If you are using your Kappa for competition or just for show and cruising around, this kit offers great looks and even better stopping power. With our optional caliper finishes and rotor designs you can personalize the style and look of the system just for you. Anyway you option the kit though, be prepared to stop quicker and look good doing it!
