911 Turbo/GT2 2001-05 - Transmission

Designed from a clean sheet using state-of-the-art knowledge and engineering to be a better differential than any other. It uses a patent pending design to improve grip in low traction conditions. Wavetrac gives you quicker acceleration and faster cornering by driving both drive wheels instead of just one. And, it offers improved no-load performance when compared to other helical gear differentials on the market.


How wavetrac works:

The innovative, patent-pending, wavetrac device in the center of the differential responds during the exact conditions when zero or near-zero axle-load occurs. At or near zero axle-load, the axles (and therefore each side gear in the differential) start to turn at di...(choose a part on the right to read more)

The new fortune auto generation 5 internal floating piston is considerably lighter and uses a low-drag teflon band that drastically reduces stiction. This allows the damper to react quicker to shock forces. The fortune auto 500 series damper shaft seals have 40% less drag than our previous models. This provides for less hysteresis and for superior control of driver inputs. Our new seals are made of a specially formulated buna rubber compound that provides a great balance between reliability and performance! Since the shaft seal is the most important seal on the shock, a stronger seal will greatly improve quality and performance.shims are deflection disks that cover up the port holes on a piston. They regulate t...(choose a part on the right to read more)

Motorsport quality for the ultimate durability and power on the street and track! Developed and tested to survive the grueling environment of endurance racing. Shorter length headers tend to crack on cylinders 3 and 4 under the higher heat and vibration at the track. Shorter pipe length does not have room to expand like a longer tube header which causes the cracking. Our double push-piece design on cylinders 3 and 4 allows the shorter length header to expand under these conditions and prevents cracking that has always been an issue on cylinders 3 and 4. FVD Brombacherheaders are the only headers on the market which feature this innovative design ensuring years of trouble free operation. Through countless hours...(choose a part on the right to read more)
