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.
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!
