I had front strut, rear, and pillar bars in my Si, but it was purely for show. never felt any thing with it. However when I installed sway bars or anti roll bars, it made a difference. Are there any sway bars out for the w204s?

And Weltmeister (who is a manufacturer for drivers in NASA and ALMS, SCCA) built a machine that tracks the movement of the tower. It's commonly thought that they move in and twist, etc.. But they actually move out. They describe it this way:

"The design people at Weltmeister built a testing device to record shock tower movement under load. Their tests revealed a surprise, shock towers do not collapse inward. Rather, they spread apart under hard cornering. The cornering force from the tire’s contact with the road, up through the strut, acts like a lever pulling the top of the struts apart. Only 15% of the camber change could be attributed to shock tower movement. The other 85% took place in the rubber mounts on the top of the shock absorber."

Here's Porsche describing it: "Under tension the coil tower tops are being pulled away from each other. The struts tend to diverge under heavy cornering forces leading to poor directional stability."

Here's Paragon's description: "Have you ever wondered why, during hard cornering, your car handles differently? Well, racers have discovered that this is due to the shock towers spreading apart. When this occurs, positive camber is induced into your suspension causing the car to handle poorly. To reduce this positive camber, racers have put a strut brace between the shock towers to maintain the proper camber.

Yes, it's an old topic. fwiw, the good ones for Porsche are made of aluminum. And to answer the question of adjustment, it's moving in and out because of the distance between the struts and how much you want it to pull outwards.

Like I said, maybe it's just a Porsche thing(?) Afterall, the brace goes in the trunk up front where there's no motor. With the C63 the motor mounts and the flex of the motor itself maybe create additional issues. My car's been corner balanced and camber set for the handling I want and the strut helps keep it there.

I would start off with the sway bar first as you will see noticable improvement, then work you way to the strut brace.

As far daily driving to and from the office, you may not feel a large difference with applying a strut brace. But, on those weekend days of driving through the twisty mountainous roads, our test drives showed a difference in handling from the stock c-class.

This was posted by 220S, who couldn't have explain the functionality of the strut tower brace any better. (hope you don't mind 220S).

I be interested in hearing from anyone that has one..does it make a noticable difference?
