We have done literally hundreds of transaxles over the last 18 years including many Daytona 24 hour setups with little or no discernible wear in teardowns afterward. We use factory processes to determine pinion depth and backlash to ensure the long life and quite operation of your ring and pinion. Recent evolution of sophisticated EFI conversions for turbocharged cars is placing heretofore unseen stresses on Porsche transaxles. Based on your application, we can enhance your 930, G50 or RUF 5 speed to better cope with additional power demands. Full rebuilds, ratio changes, upgraded synchro's. Supllemental lubrications systems added. Ring and pinion changes. Positraction added/changed and locking factors set to your request.
