I installed the Lindsey racing short shifter on its own first. It was nice, and allows for some adjustability. Though there is actually much less than they imply because too much or too little either way may not allow you to get into gear depending on a variety of factors. That made the install a little frustrating but finding the sweet spot isn’t too hard. it was still a little sloppy for my tastes so I then installed the only944 short shifter linkage and linkage arm combo. Once everything was dialed in and adjusted right it’s the best feeling shifter I’ve used. Decently short throws both forward and back and side to side, no slop. A little hard to engage (even with a flush and redline fluid) but that’s expected with a shorter throw and still much better than before. It’s my favorite thing done so far. Otherwise the car came with a chip (I have a pic, forget which one but it pulls decent throughout the rpm range) and the throttle response cam.
