Developed exclusively in conjunction with the UK’s leading motorsport transmission specialists, Quaife Engineering. This kit is a direct fit to all 105 series Alfa Romeos and uses the original bellhousing and clutch set up. We have a developed a bespoke gear ratio set with a 2.4:1 first gear, running through to a 0.889:1 6th gear, with the result that there is no need to change the standard Alfa rear axle ratio. Other ratio sets are available by special order. The kit is supplied as standard with a gearlever for manual shifting. An optional ECU-controlled semi-automatic paddle shift system is available, […]

Designed for use with the Alfaholics 6-speed sequential gearbox. This kit allows full throttle clutchless upshifts and clutchless downshifts with throttle blipping to match engine revs to gear speed. The system incorporates the very latest ‘closed-loop’ software using an ECU in conjunction with feedback sensors to modify its own operation in response to the sensor inputs, all in real-time. It uses these sensors to monitor the gear position sensor to determine if and when a shift has been successfully completed. This information is fed back to the ECU so that the pneumatic actuator, engine torque reduction or throttle blip can […]

Superb new production, manufactured exclusively in the UK for Alfaholics by a state of the art limited slip diff manufacturer. These new diffs represent a huge leap forward in design over our old Gripper units. The old Gripper units used a basic uncoated steel friction plate design and, as a result, necessitated a very high preload setting in order to achieve the levels of friction required in a race diff. The new Alfaholics racing diff uses the same copper sintered friction plate design as developed by leading World Rally Car teams – M-Sport Ford and Prodrive Subaru. This high-friction coating […]

New design, premium quality and ultra strong. Available in both 25 spline ‘GT Junior’ and 27 spine ‘GTV’ sizes. These halfshafts feature a built in lock ring for the wheel bearing, making wheel bearing changes far simpler than ever possible with standard Alfa shafts. The end flange is scalloped for a useful weight saving.

New production – exclusive to Alfaholics. We chose to manufacture these new premium quality synchro rings due to the continuing issues with the reproduction rings currently available on the market. It is common knowledge among Alfa racers round the world that the reproduction rings are not made to the correct tolerances and this leads to baulked gearchanges and premature molybdenum coating wear, particularly noticeable during track and fast road use. Until now there has been no solution to the problem, as only the standard reproduction rings have been available. Up until 10 years ago when the genuine Alfa synchro rings […]

New production – exclusive to Alfaholics. We chose to manufacture these new premium quality synchro sleeves due to the availability of new original Alfa synchro sleeves finally ceasing in 2012. When this happened, we tried first to source the already available reproduction sleeves to try them out. When they arrived we noticed an obvious difference in tooth profile which made the rings hard to slide in and out of the sleeves on the bench. During driving, gear baulking, not dissimilar to using the cheap reproduction synchro rings was observed. At this point we knew that we had no option but […]

This superb GTA close ratio gear kit has been manufactured exclusively for us by the UK’s leading transmission manufacturer, Quaife Engineering. Unlike any other kit on the market, we have directly copied an original GTA gear kit. As a result, the gears are not only scooped, but they are also drilled for further weight saving, just as original GTA gears. The layshaft is rifle drilled, as original, for further weight reduction. All these weight savings and consequently reduced inertia, result in a gearbox with a lightning fast shift speed both up and down the ratios. Not only does this mean […]

As per above kit but put through a final REM Superfinish process. This process polishes the surfaces of the components at a particle level resulting in a super smooth chrome appearance finish. This finish results in the oil getting worked less hard inside the box resulting in reduced frictional losses – the result of this is a nett gain of BHP at the rear wheels.

We have designed and manufactured this 8-bolt crank (10mm bolt size) with 105 tooth ring gear for all early 1300/1600 cable clutch applications flywheel to combat the inherent vibrations that occur in all high revving 4 cylinder engines. These vibration harmonics reduce bearing life and in worst case scenarios can cause catastrophic (more)

For years the rubber front propshaft coupling (doughnut) has caused racers huge headaches and retirements from races. Doughnut distortion is caused by high centrifugal forces developed at high speeds. This causes the propshaft bush and gearbox mainshaft ball to wear unevenly and consequently the propshaft spins like a skipping rope and the doughnut itself starts opening out, EVEN when using a GTA doughnut cage. Symptoms range from vibrations which lead to broken clutches and bellhousings, right through to the doughnut exploding which can cause huge damage to the drivetrain and tunnel. We have developed this superb system to eliminate any […]

Exclusively manufactured for Alfaholics to exacting tolerances. Most rear propshafts have had many UJ changes in their life and as a result can often have damaged UJ housings, this means that even with new UJs vibrations can still occur due to end float in the UJ housings which is beyond shimming out. The sliding joint is also another area for wear on an original unit that of course cannot ever be repaired. As a result of these 2 major factors we no longer use rebuilt rear propshafts in our workshop, fitting only our brand new unit for 100% perfect results […]

Ultra lightweight full length race-spec propshaft – just 7.9kg total weight including the heavy duty centre support! Manufactured exclusively for Alfaholics by Formula 1’s choice balancing company using race-grade ultra stiff 2″ diameter tube and fitted with 3 heavy duty race UJs. The UJs are also scalloped for additional weight saving. Once manufactured, the entire unit is balanced to 10,000rpm to ensure perfect balance at all speeds that it will experience in use. It is worth remembering that all 105 series gearboxes run an overdrive 5th gear so the propshaft can spin somewhat faster than engine speed! Those with experience […]
