Kartboy Shifter Lock 2015+ WRX

The Kartboy shifter lock reduced left-to-right play in the shifter of the manual-transmission 2015+ WRX, to give a tighter shift pattern with less slop. Installation is easy -- we installed one on our own shop car in about 20 minutes.

Some products of this type are made of metal, which can causing clanky noises when the shifter comes into contact with the stop. The Kartboy part is made of a very strong glass-reinforced nylon, so it is nearly silent.

Here's a helpful install video:
