The short shifter from Neu F for the Fiat 500 shortens the shift throws and reduces slop in the linkage.
It's an inexpensive mod you will enjoy every time you drive the car. Installation is easy and takes less than an hour.

The design is simple but elegant. It's very precisely machined and alters the shifter's geometry slightly to shorten the throws. Because it's so perfectly made it also reduces some slop in the mechanism.
I find the car to be much more enjoyable in normal driving with this mod, and for performance driving the shorter throws are a big plus.

If you're looking for a simple way to improve your Fiat 500's driving dynamics without breaking the bank, this short shifter deserves serious consideration.
