Tracking the 107

I wanted to track my 560 at laguna seca, and was wondering what I would need to change/check before I go. Thanks

You must add around 6 psi more to your tires than normal.( since the speeds will be higher). Check that thread of the tire is ok, brake disc and brake pads.
Let the car warm up very well before taking it out, after some laps go in to the pits and let it cool, don´t put the handbrake on, because if I am not wrong this will lean the brake pads against the brake discs and the brake fluid will boil.
But are you complety sure you want to put the 560SL through this test??, they were not really designed for track use, and some new noises or problems may appear after you trackday.
Anyway, be safe all the times, and never drive over your own limits.
Trackdays are a really good experience with the correct car.

Regards and tell us how it went.

I would actually change the brake fluid before doing this; also, make sure that your motor mounts and flex disk(s) are in good shape. Someone on another forum autocrossed their 560SL and broke the radiator neck; the reason that this happened was determined to be a loose motor because of broken mounts. No way to know if they broke during the event or were broken beforehand.

How are your exhaust hangers?

BTW, I have no idea how to actually examine any of the above components to determine if they are about to break. If they haven't been changed, they have to be 18 years old or so...

It has been almost 20 years since I last drove a W107 on the track. It was at Road America where AMG held the event. Even Mr. Aufrecht was there for the press.

There was a 5-speed manual SL with the 6.0 and all the works of course. The upgraded brakes was a big improvement; but still working pretty hard for the heavy car.

thanks for the help. Basically I should check all the mounts, oil, tires, and brakes before going out. I know the 560sl was not really designed for the track, but nevertheless it is a very fun car to drive.

Make sure your transmission has fresh high quality oil and your rear differential as well. The stock auto 4 speed box will overheat if fluid is old or of low quality. Your basically going to need to give your car a good once over, make sure engine is tuned up and ALL fluids are up to snuff. The 107 while not a hot rod has very robust components and is not as delicate as some may think. Remember, the did rally the coupe versions (SLC) in many a African rallies and also in the middle east. One of the biggest short comings of the 50 state cars with the M117 is the EXHAUST system. The cats really choke it up and the whole system is designed with quietness in mind. remember the euro M117's make a full 62 hp. more than ours (that's huge) Enjoy your car! just make sure everything is 100%

Thanks, that brings back many fond memories. Schnitzer used better components (titanium piston rods, Mahle pistons, Schrick cams., cast iron headers, etc.), I had two of their CSL. Total weight with the Matter roll cage was under 1,100 KG. Great cars. I totaled one in Germany, and had to leave another behind when I left Iran. Finding someone over there capable of synchronizing three double Weber 45's was quite an experience.
