The FX100 System uses the Power Plus I Pressure Plate with a custom heavy-duty Steel Back Organic friction disc. This clutch is engineered for heavy-duty street use. It is specifically designed for extended wear and additional clamping force for the enthusiast who has added an exhaust system, an intake system, up to 50hp NO2 upgrade, or other non-forced induction external bolt-ons. It features only slightly increased pedal pressure, longer life than stock, and normal clutch feel during engagement and disengagement for a very smooth operation. Learn More

Todays sophisticated tuners want it all; and GReddys SE exhaust systems deliver the full spectrum of features desired in a street performance system. SE exhausts increase flow via tuned piping and larger; free-flowing mufflers for improved power; but provide discreet sound levels that wont attract the wrong kind of attention. The exhaust note is comfortable and sporty; not loud. Each application is tested and tuned for USA spec. vehicle'so fitment and sound is confirmed. All SE Exhaust are test to be well below the 95dBA standard. Our new smaller Spectrum exhaust tip(s) help disguise the system from the rear of the vehicle; but reveal show-quality appearance from the side and underneath. Whether you are cruising down the road or at wide-open throttle down the track; the Spectrum Elits ready. Refined sound. Hard-hitting power. Superb looks. Excellent fitment. GReddy quality. A true Sports Exhaust. Learn More

For over 40 years; Cosworth's been leader in innovative multi valve cylinder head design both racing high performance production cars. Cosworth Ported Valve Cylinder head range is latest advancement. Modified from OE cylinder head castings; substantial flow improvements upgraded valve train components offer superior performance your high performance engine.
Each original cylinder head design is carefully evaluated tested to establish improvements required to meet target performance level. Hours of testing flow bench validation used to determine best advanced port design yielding maximum usable power response. However; there is more to cylinder head design than just maximum flow. It is critical that port velocits maintained to ensure drivability valve train components matched to guarantee reliable performance. Once of these factors have been tested validated; final port contour is digitized. Using digitized program; we then reshape both intake exhaust ports using axis mill producing an accurate consistent port shape every time. In addition to reshaping enlarging intake exhaust ports; most Valve Cylinder heads feature a re-shaped combustion chamber to un-shroud valves increasing flow performance. After machining; each cylinder head receives a multiangle high performance valve on precision valve seat cutter. Then each cylinder head is ultrasonically; cleaned; serialized then hand assembled with select high performance valve train components; ready to install on your engine.
