Introducing Boomba's latest product for the 2015+ WRX. This billet aluminum shifter stop is CNC machined in house at our facility in Wood Dale, IL. It's designed to drastically reduce shifter play while in gear. It essentially removes all the additional play your shifter has while in the 1st, 2nd, 5th, and 6th gear gates. Pair this with our brass bushing, short throw shift lever, and shift plate; and you have a recipe for nirvana.
