100 octane OK to use on stock engine?
I'm going to the track on Sunday in my stock 03 S55 for the first time. My friend recommends using a half a tank of 100 octane.
I've heard racing fuel may slightly improve performance, but my question is, can it do any harm to my stock engine?
Thanks,
qcar

FYI - I went to a well-run driving school at Willow Springs, CA raceway set up by the BMW Club in LA, which welcomes all makes of cars. It's about a 2 mile track with 9 turns and 2 straights.
It was real fun and my S55 performed beautifully. It's no track car, but for its size the BMW guys (and my instructor, who also drives a GT3) seemed pleased with the S55's handling. Of course, it made a good impression on the straights. People in the pits approached me later and said they could feel my car's thunder-like rumble in their chests as I passed by at 125. And I have a stock exhaust.
What I like most is knowing that my car is rock solid under extreme (for me) driving. I came off the track, got on the freeway and it drove home smoothly and quietly, like I had just come from the grocery store. It's as if the car was yawning, saying "is that all you've got?"

The only thing to watch out for is that some race fuels are slightly leaded...which can cause some problems in the cylinders if you run it too often.

qcar,
I knew you would have fun tracking your S55. As to the 55 engine, it is a solid piece of engine technology. I have done the AMG Challenge series a few times and these cars perform flawlessly being pushed around the various tracks all day.
Can't say the same for other makes though.

One of my lug nuts was put on so tightly by the guy who did my brakes that I broke two socket extenders removing it.
