Motor Sport Parts

This 2mm spacer ring allows for a much easier setup when retrofitting some differentials and or crown wheel and pinions within the 915 family.

Note
Longer ring gear bolts may be required

Our spray bar, made from stainless steel, is an excellent reproduction of the factory RSR spray bar. It allows for gear lube (presumably from a remote pump and cooler) to be returned directly to the gear mesh, including the final drive gears.

** This requires machining to the front "nose cone" housing.

We have updated our 915 spray bar kit to include an improved oil return port that will not interfere with the torsion bar tube and allows for better routing of the oil return line.

Fits all Porsche 901/911/912 aluminum case transmissions.

It's not uncommon for one or both bosses that capture the pivot shaft for clutch release fork to crack or break off rendering your clutch inoperable. This is a repair kit and will require some machine work and a strip and rebuild to professionally repair your bell housing for a fraction of what it costs to replace the housing or the entire transmission. 993 bell housings remain no longer available.

Our current version uses hardware to reattach the new bosses rather than welding making future replacement much easier. This is the cleanest repair in the industry.

Uses the current version pivot shaft and fork assembly.



For all G50, G64, 993, 996T/997T, 996/997 GT2/GT3 transmissions.

Machined in house from 6061 billet aluminum
Nicely beveled edges; high attention to detail
VDO 300F temp sender included
-8AN adapter included
Mounting hardware included
For all G50's '87-'98 except C4 5 speed

The original Porsche 930 transmission differential side cover is made of cast aluminum, not to mention it's pretty thin.
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 significant strength and increased reliability to the differential section.

Our design features include:

A ring gear thrust bolt to reduce ring gear deflection under load
Ports that can be used for an oil cooling system
Cross drilled oil passageways for the differential bearing

Comes with (3) 3/4 - 16 O ring plugs.
