Rennshift is the shifter designed to transform the driving experience of your classic Porsche. Let's face it, the shifting of the early 911 and side shift 914 left something to be desired...and that's perhaps an understatement! The Rennshift features all new parts so you won't have to reuse your old housing or stick. You can also easily switch between 20% or 33% throw reduction. Adjustable bias spring gates can be tailored to driver preference for precision shifting. Over travel stops give solid feel and protect inkage and transmission. The Rennshift will accept your original shift knob, most aftermarket knobs, or one of Rennshifts custom knobs.
