$199.00Manufactured in UK; Cosworth brake pads feature a 1.5mm granulated inter-layer which only serves to as a shock absorber; helping to reduce stress on rotor surface triples bonding strength; diminishing edge lifting. To reduce bedding-in or seating-in time - this is time it takes the and disc to adapt to each other - Cosworth brake pads heat seared. This process heats friction material to in excess of degrees toasting surface ; greatly enhancing performance first time that driver applies brakes. Scorching pads also significantly reduces initial fading - fading increases necessary force pressure required to maintain deceleration of vehicle. Cosworth's brake range offers exceptional performance without compromise. Learn More -

$4,313.00For 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.

$325.00GReddy Blow Off Valves are easily adjustable to eliminate compressor surge and preventing premature boost leakage; while increasing boost response between shifts. Each valve is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer. The spring stiffness adjustment screw and the three different sizes give the GReddy user the option to match vehicles with mild upgrades to heavily tuned engines. There are many factors in matching a blow-off valve to an application; valve location; turbocharger size and pressure; but as a general rule of thumb; we recommend the Type RS for 100-400hp. Also available in easy to install kit form for many turbocharged vehicles.
The Type RZ Blow Off Vale; is identical to the Type RS except for the fact that the RZ is a special limited edition color. Learn More -
$14,390.00JRZ Suspension Engineering is proud to offer our newest quadruple adjustable racing damper. the JRZ 14 31. Building upon the years of success of our original quadruple adjustable. the 14 31 takes our damping philosophy to the next level. Every adjustment has an increased damping force range with finer adjustments engineered to enable the chassis tuner to make significant. predictable changes every time. Compression and rebound adjustments are separated into the high speed and low speed piston velocity ranges affecting the bleed and blow off points of the damping curve. All oil flow paths in the JRZ 14 31 have been redesigned to maximize efficiency and give crisp feel to the driver. Rebound valving has been completely redesigned to eliminate influence over compression forces and smooth pressure development. At the heart of the new JRZ 12 31 package is our latest motorsport piston. designed to give increased control over base characteristics. reduce hysteresis. and operate smoother. To ensure that the valving designed into the JRZ 12 31 are the determining forces. JRZ has included new low friction coatings. seals and bearings with this package. Custom applications are available. An easy to use system. the JRZ 14 31 enables the chassis tuner to achieve the desired mass control and handling with precision. Digressive high speed blow off adjustment allows for highly tuneable mass control while maintaining smooth response and without losing traction. The low speed bleed adjustment is a powerful tool that enables the chassis tuner to maximize grip and optimize vehicle balance.
