RennShift 930 4-Speed Shifter

RennShift Performance Shifter for 930 4-speed transmissions used in the '75-'88 911 Turbo.  Does not work with factory '87 and '88 bolt-on shift knob.

• Adjustable Throw, Adjustable Spring Gates, Bronze Bushings and much more!

• Spring bias puts the shifter in the 3-4 plane.  Pulling over to the 1-2 plane is natural (same as nearly all 5-speeds) and is the common design for 4-speed shifters.  Other's designs recycle the 5-speed shifter and leave the spring bias to center on the 1-2 plane - very unnatural to drive!  

• Reverse spring is internal to the transmission.
• Shift Rod Bracket, Shift Rod Bushing, and Shift Rod Bushing Socket are included with the 930 shifter.  These are unique to the 930 with it's special throw requirements.
• Shift feel and accuracy of selecting gears are improved tremendously, even compared back-to-back with fully optimized and blueprinted factory short shift.  This is not a "boy-racer" product, but a true shift system designed specifically for the Porsche transmissions.  Aerospace engineer designed with our initial 901 shifter improvement dating back to 1985.  RennShift general distribution since 2003.  We've been at this a long time.
• Complete shifter makes installation simple.
• 20% and 33% throw reduction can be changed at any time.  20% with stock length stick and 33% setting with extended stick are optimal for most cars.  Greater throw reduction offered by other companies are not recommended for 930 type transmissions - shift force becomes too high and you have to "bang" the shifter into gear, wearing out the synchronizers.  These are not Muncies or Hondas! 
  
• Works with factory '75-'86 shift knob with crush sleeve on outer surface of stick or our optional shift knobs which thread into internal threads with a stud.
• Includes small RS boot.  Can be used with original factory 915 boot, which when combined with a stock knob looks close to stock.
• Stock height puts the shift knob in the same spot as the original Porsche shifter, both vertically and front-to-back.  The extended stick adds 2 inches along the angle of the stick, moving the knob up and back for more comfortable reach to the forward gears.
