Project M3 short shifter comparisonAnd with everything installed and buttoned back up, it’s time to check our new shifter’s distance between throws. Again, very scientific measurements taking place here.
Project M3 short shifter comparisonThe resulting shifter throw distance from first to second gear changed from about 4.75 inches with the stock shifter assembly to an impressively short 3.25 inches. That’s a significant difference, and it very likely saves measurable time over a given number of laps on a race track, but the shifter swap is about much more than just lap times. The Octane SSK gives this little BMW the shifter feel it really should’ve had from the factory, with no drawbacks.
Project M3 BimmerWorld Group N engine mountsAs mentioned, it was obvious that the engine mounts were in need of replacement based on the movement exhibited in the drivetrain, and anyone familiar with BMWs of this generation knows how easily a missed shift can happen. Once you zing the motor past redline, it becomes pretty much a giant doorstop. I don’t need any help keeping doors open, so a set of BimmerWorld Performance/Track Engine Mounts was installed along with the shifter.

These BW mounts are similar to Group N BMW engine mounts, but considerably less expensive. They significantly reduce engine movement because of their solid design, but they’re still rubber. Because of the solid construction, there is a bit of an increase in NVH, so those who are sensitive to such things may want to just go with factory M3 mounts on their street cars. The added insurance against movement for those who go on track is worth the very slight sacrifice, though.

Project M3 engine jacking pointOnce unbolted, you do need to lift the engine up every so slightly in order to remove the old engine mounts. It quickly became evident just how compressed one of our factory mounts was, however, as one side of the engine required considerably more lift than the other.

I'm happy to see E36 M3 content on here!

A short throw is desperately needed on these cars. They're what the car should have come with stock. Also somewhat related (and the absolute first thing I did when I got my well used M3) is the clutch pedal bushings. Those plastic POS bushings wear out and the clutch pedal starts wobbling around like a drunk. If you haven't yet, spend the $20 and get delrin (or some people make bronze ones) clutch pedal bushings. The install is... a delightful challenge. I've also heard great things about Mason Engineering's metal replacement clutch pedal but have no experience with it.

How are the Bimmerworld engine mounts at idle? I briefly installed some AKG engine mounts that were relatively soft but were a bolt through design. The car felt like a damn massage chair at idle, especially with the AC on. So I just went back to new OEM ones, but I've always thought I should've gone with the Bimmerworld Group N style.

Agreed that the short shifter is almost a necessity. At least from a personal standpoint. I'm surprised how many people actually like the long, soft throws - or maybe they're just put off by some of the other shifters that make the notchiness almost unbearable.

I haven't had to deal with the sloppy clutch pedal on any of my E36 M3s yet, despite racking up a lot of mileage over the years. I'm on an enduro team with a 325i, however, and we already have delrin bushings ready to go into that one.

If someone is looking for factory-based silence, I wouldn't recommend the Group N style mounts. I ordered them from BimmerWorld knowing that there would be a bit of an increase in NVH, and it was about what I expected. There's a bit more vibration at idle, but certainly not bothersome. I've grown used to it and don't even notice it, but it's probably very dependent upon driver tolerance.

My e36 came with a shortthrow. I hated it. The short throw makes the shifter stiffer(shorter moment arm). I fixed it by going with a long shifter(TRM 7"). Now it's fantastic. The short throw crisps up the shifts and the long shifter keeps the effort low and move the shifter up near the wheel(where it should be!).

I put M3 motor and trans mounts on my E46 325. It greatly improved shifter feel and precision. It did however add some vibration at cold idle and a resonance vibration around 2k rpm.

I also added the Mason clutch pedal and love it. It's especially nice for guys with long legs. I see EAS also has a similar pedal available.
