  4. Clutch Masters 15013-HDCL Subaru Impreza RS FX400 Clutch Kit
    $598.00
    For: Subaru Impreza RS YR: 1994-1995 Cyl: 4 App: 1.8L 4WD
    The FX400 System uses the Power Plus I Pressure Plate with a custom, extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 4,6 or 8 wing (paddle) configuration, with the 4-wing being the more aggressive setup and 8-wing being the less aggressive (please specify which type you prefer). The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for outstanding holding capacity, and rapid heat dissipation. The FX400 ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that may not be ideal for street driven vehicles.  Learn More

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.
