	ALBINS G50 6 SPEED/993 BILLET SHIFT FORKS (all models) The original forks are cast and sometimes break or will simply wear out. Billet forks are stronger, more reliable and are commonly used in factory race transmissions. We currently manufacture forks for: 1^st/2^nd gear position $350 3^rd/4^th gear position $440
Non turbo version Turbo version with ring gear thrust screw	CMS G50 6 SPEED/993 BILLET SIDE COVER The original differential side cover is made of cast aluminum. Under load there can be a tremendous force applied to this cover, and it can break, sometimes resulting in a damaged ring and pinion-or worse. Upgrading to a billet side plate will add strength and increased reliability to the differential section. Our cover features an oil passageway for diff bearing and accepts the standard taper bearing, radial seal and O-ring. The turbo version further incorporates a thrust screw to reduce ring gear deflection under load. · 993 billet side cover $399 · 993 Turbo billet side cover $499
	CMS G50 6 SPEED/993 BILLET SIDE SHIFTER CONVERSION (all models) This patent pending design moves the main shift shaft to the side of the transaxle case allowing for a neat and tidy way of attaching shift cables. Perfect for some mid-engine installations and especially where space is limited behind the transmission. Shift cables can be attached or retrofitted to a variety of shifters including the CMS billet cable shifter. · $999 (installed price) · $899 kit price (requires your gear housing and shift shaft)
	CMS G50 6 SPEED/993 BILLET END CAP CONVERSION This conversion was originally designed for custom mid-engine installations, and is useful when installation space is limited as it will yield approx ½ inch of additional clearance at the tail of the gearbox.  The end plate is available in two versions, with and without the provision for the shift shaft.  This also works well for some rear engine applications.  The conversion requires a different tail housing to be used. $495
	ALBINS G50 6 SPEED/993 GEARS Stock gear ratios are designed for drivability and fuel economy and not necessarily for best performance. Whether you have a stock motor or one that has been tuned your transmissions’ gear ratios may not be optimum for your driving needs. Optimizing your gears to match your engines’ power curves can make a huge difference on the track, often resulting in reduced lap times, and can give the sensation that there has been a gain in power. Alternative gear ratios can make the car more fun to drive or be more drivable. We carry a wide selection of OEM and Albins gears to suit a variety of applications. · 1st gear set (weld on type; requires core OEM input shaft; requires additional labor-not included in price) $945 · 2nd gear set $945 · 3rd, 4th or 5th gear set $915
	ALBINS G50 6 SPEED/993 FINAL DRIVE/CROWN WHEEL AND PINION The overall gearing in your transaxle can be reduced or increased with alternative ratio final drive gears. We offer OEM replacement sets as well as Albins made sets-and in ratios that the factory never produced. These high quality hypoid gear sets are produced on the same cutting equipment and with the same design as OEM. Ratios currently available are: · 3.10/10:31 (special ratio for V8 and turbo applications – fits 2WD non turbo gearbox only) $2925 · 3.44/9:31 (stock ratio, C2/C4/Turbo) $ inquire · 4.00/8:32 (improved street/autocross/track ratio – fits 2WD non turbo gearbox only) $2925 BREAK IN RECOMMENDATIONS

	CMS BILLET CABLE SHIFTER/SHORT SHIFTER (Designed for use with G50 cable shift converted transmissions and factory cable shift transmissions) Modeled after the Porsche 996 cable shifter, our assembly incorporates a B&M standard issue short shifter (45135). It’s conceivable that other shift kits can be installed as well. We have not verified this however. Additionally, depending on which base plate is installed, the CMS billet cable shifter will accommodate either custom made to order (2” or 3” throw) shift cables OR factory shift cables (e.g. 996). The nature of the application will best determine which base plate and cable combo is best. Other features include: · A 35% reduction in throw · Side to side free play is eliminated as found in OEM shifters · All parts (minus B&M’s parts) are precision machined from billet 6061-no parts are stamped or cast CMS billet cable shifter assembly with B&M 45143 (comes with plastic B&M shift knob) $849 The shifter can be ordered without the B&M shifter too.
