When i do this mod, i plan on adding a bolt, screwing it into the firewall and thigtening the bolt up against the firewall. I figure that if you put some torque on the screw with the bolt, it will stay put and not turn as easily. Anyone do this before?

hmm, from what the pics are showing it looks like you just have to screw it in all the way, since stock unit is was shorter than the elevator bolt....thats where you gain that extra height from the longer bolt itself not by adjustment, but thats just my 02 cents

I found one. Works great. Found out something interesting about the car also (maybe only to me). If you turn the key to start without engaging the clutch, then slowly engage the clutch it will start up when it is pressed far enough. That is the max you can have stop stick out and it is still far from the catch point.

If your clutch engagment point is near the carpet, the stop bolt does nothing. If your clutch engages halfway or near the top the bolt just stops you pressing the pedal all the way to the carpet, that is, it eliminates unnecessary travel.

To adjust the bolt to the correct setting you need the engine running then press the clutch all the way down and select a gear....while you are holding the clutch pedal down with your foot ask a friend (if you own an M3 you will no doubt have lots of friends) to measure the pedal travel...while your friend is down on his hands and knees with his head in the footwell start lifting the clutchpedal up slowly and WATCH the tacho needle (handbrake ON !!!) when you see the tacho needle start to fall your clutch is starting to bite. Note that position ,for example carpet to pedal 1.5" now deduct half inch = 1", that is the distance that your clutch stop should be from the measurement point on the carpet.

The extra half inch travel is to prevent premature clutchwear.
