A common BMW insider's trick is to use a shift lever from another model to make your own short shift kit. BMW has picked up on this retrofitting with their own series of short shift kits using all factory BMW parts. BMW Performance shift kits are among the most complete and easiest kits on the market - shift lever, nylon ball cup, boot, and shift knob are included in most kits. This is everything you would need to replace when installing a shift lever plus a new knob to top it all off. Shifts are reduced by 25% on most models. With a fresh lever and bushings you can restore precision and feel to your shifter. BMW short shift kits are easy to shift - not excessively notchy. This makes them perfect as a shifter refresh as well as an upgrade.
AAF Racing have been building race cars for more than 8 years and have been installing all types and brands of after market shifters. Using all of that knowledge, AAF has incorporated all of this into their new innovative design. AAF's BMW Race Shifter with Adjustable Shift Shaft has a very wide array of available adjustments allowing you the ability to tune it exactly to your liking. If you want to change something about the way it works, most likely there is an adjustment for it! Adjustable Features: Throw Ratio: The knob height must remain at the same height and position for obvious ergonomic reasons. This means in order to incorporate a throw ratio adjustment WITHOUT changing the position of the knob or the pivot point, the location of the shift shaft connection must move closer or farther from the pivot point. This is done in the lower section of the shift lever. Adjustable Shift Shaft Included: Included is the AAF Adjustable Shift Shaft as they believe this allows for optimal shifting. With an adjustable shift shaft, you are able to move the shift knob forwards or backwards, as well as left or right (closer or farther from the steering wheel). You can make all these changes without affecting the spring position of 3rd and 4th gears. The shift shaft has an adjustment range from 165mm to 245mm. Knob Height: The AAF Race Shifter is capable of a total knob height change of 50mm while still having 3 different options for throw ratio. There are two knob spacers included, a 25mm and 50mm. This allows you to thread the knob down tight and lock it into place. Spring Center: Coupled with the AAF Adjustable Shift Shaft, the position of where your AAF Shifter springs to center is totally adjustable. There are two screws per center locator that can be used when setting your center position, then the upper cap will be locked down to ensure your center preference position never moves out of adjustment. Spring Pressure: One of the most unique features of the AAF Race Shifter is the centering spring mechanism. Unlike most shifters that use a typical steel spring, the AAF Race Shifter uses a polyurethane spring. This polyurethane spring absorbs shock and vibration load that a typical steel spring would magnify and resonate. This gives the AAF Race Shifter a connected feel to the transmission that is unmatched. It features two polyurethane springs. This allows the adjustment of the centering location of each spring independently which gets rid of any slack but also allows for preloading of the spring. AAF also offers multiple different spring rates of polyurethane which are preloaded in house. Mounting and Installation: AAF's Race Shifter is centered directly over the factory shifter hole. This allows it to be to be installed in many BMW applications. All other information and installation details available on AAF's website!
