2008 Ford Focus WRC Tarmac setup.
Shows 2 piece rotors, rotors are massive. Interesting anodize coloration, possibly due to the alloy? What brand of Dampers are these?? I see ___EIGER ... Interesting that the remote res is kept close to the damper. In the second pic you can see the upright and radial brake caliper mount. Michael LeCompte |

Yeah the setups they have for suspension cost more than your car. The coloring is probably from alloy and being superheated. If you have ever watched the tarmac stages at night those things are a source of light for the drivers practicaly. Awesome shit

As far as the dampener resevoirs being close to the damper, perhaps it's to keep mass low on the car. I've seen articles where Ford works really hard at lowering and moving mass to the center of the car as much as possible.

The color comes from the heat treating process when they flood the oven with Nitrogen to keep the part from oxidizing. |

I would doubt such a highly stressed part would be SS, but I am just guessing. SS is not a very strong (or light) material. to me, the hat looks like it has to be Ti with some sort of finish. Perhpas anodized. |

Precipitation hardened stainless is an extremely strong material. If you look up the material properties you will find the ultimate tensile strength for 17-4 H900 is around 200ksi. Although you wouldn't use it in that full hard condition though because it's quite brittle. I would bet against titanium because it's generally avoided for thinks that need to slide (see the floating bolts attaching the rotor). It cannot be surface hardened and while there are a few surface treatments but they're thin and fragile. |

When I think of stainless, I usually am thinking the 40-ish ksi range, i had no idea you could get stainless up there north of 90ksi, where things like commonly available al and steel alloys tend to top out. True, Ti tends to gall in certain situations, but aren't brake buttons themselves often made from ti? I thought so.... |

I thought so.... The PH stainless steels are magical. Relatively easy to machine and they don't warp at all when heat treated. They actually shrink something like 0.05% evenly in all directions so you just scale up the part by that amount and machine to the larger dimensions. I'll try to find a picture of the last part I made out of 17-4...the coloring is identical to those brake hats. I've only seen a few buttons in Ti, some are case hardened steel, Tilton used to have them sintered out of powdered metal, and some are stainless. All depends on the manufacturer and how heavily they get loaded. You tend to see Titanium more in motorcycle rotors. Really, only a fool would mount their rotors with custom Titanium t-nuts like this ![]() ![]() |
