I FINALLY got around to installing the Dinan short shifter. I wanted shorter throws and more precise shifting.
This is the model I got for my 335is but it works for alot of other applications

1. Before you begin, I highly recommend you buy a new shifter ball bushing (instead of taking out your old one and transferring it) because snapping it onto the Dinan shifter is by far the hardest part of the installation. If you can't get this done then the rest is useless. I greased up the insides and while holding the shifter and ball bushing as steady as possible, slowly push the bushing down on one side and use a flathead screwdriver to push the other tabs one by one and it will eventually snap into place. This took me a good 30 mins although you might have better luck! Next, slide the provided black gasket ring and secure it as pictured.
2. Put your shifter into 4th and squeeze the sides of the shift boot and pull up. Remember that for the M-Sport knob, it is attached to the boot.
3. Pull up straight on the knob and it should pop out.
4. Remove the foam insert
5. Remove the rubber boot. I used a flathead screwdriver because its pretty snug but be careful not to rip it. The best way is to pull it out from either side as those parts aren't as deeply secured.
5. This is with everything removed. Now jack up the car and get underneath.
6. Use your 8mm socket to remove this plastic cover. Some of mine were secured with philip screws.
7. Bend the heatshield back and use a flathead screwdriver or your hands to push off the c-clip. I'm skinny so I was able to grab the lever with one hand and remove it with the other.
8. Push the lever out from the hole and now the shifter is ready to pull up from inside the car.
9. Back in the car, take a pair of pliers and latch onto the white ball bushing and turn clockwise about 1/4 turn. Then pull straight up and the lever should come out.
10. Put the Dinan shifter into the hole. Notice that there are two tabs on the white ball bushing that flare out a little but. These get secured into the metal grooves in the slot. So place the ball bushing into the hole and align the flared part with the groove and push down firmly. It should snap into place. You will know its secure when you can't pull out the shifter. Make sure the shifter bend is facing towards the rear left of the car.
11. This is how it looks securely in place. Get back under the car.
12. Put one of the supplied washers onto the new lever and insert into the hole. I tried putting the other washer as seen in the pic below but the c-clip wouldn't secure onto it. I believe the washer is an extra.
13. Push the c-clip onto the lever to secure it. It was a perfect fit with no give.
14. You are all done! Push the heat shield back in, put back the plastic cover, and re-insert the rubber boot (use grease on the lever to make this easier), the foam, and the knob.
Impressions: The shifting is much shorter

Love the notchyness and the gears sort of click into place. It does take more effort though to put into gear and its a bit louder, but overall money well spent. Happy shifting!
