Let me start off by first saying that I've had the amazing Lapp Racing rear disc conversion on my Fiesta SES since waaay before the ST was released - But I know that they both use a bunch of the same parts from Ford.

My question is this: does anyone with an ST have pics of their rear disc setup with the wheel off? I'm curious if the stock ST rotors have that little extra Phillips head screw to keep them in place against the hub.

I know the rear brake drum covers that I originally had on that car had that - therefore there is a threaded hole already in my wheel hubs. But the stock Focus rear disc rotors that I'm currently running don't have that hole in them - and I don't really like how I can wiggle the rotors back and forth a hair while they are mounted on the wheel studs. I feel like over time this could cause undo wear on the studs where they pass through the rotor.

Any help is greatly appreciated guys!

Our hubs are totally different.

I don't know if we have a retaining screw but I can tell you that you're not going to wear out your wheel studs because your rotor doesn't have them.

I bet Ford added the screw just so they don't have to worry about drums falling off the axle on the production line.

Ya Don't recall seeing them as I know the Honda's use them quite a bit. And the shop manual shows nothing on this pic.

That is the only reason those screws are there.

There is absolutely NO way the rotor can possibly move when the wheel is mounted and tightened.

Agreed it won't come off but it may sound like hell ...

LOL That little screw wouldn't have held that together anyway.

And that's a front not a rear.
How in hell did you do that?

Agreed and I did not do it i just found it that way oops again i defaulted to acura/honda they use them dumb screws on all rotors ..

That failure is a major casting flaw that was likely brought to light from some track use. If the manufacture process is to hot weld the hat to the rotor ...

It looks like the hat itself just broke.
I don't think welding would have made any difference.

Thanks guys - I kinda figured there was no real way the rotor was going to move that much when the wheel was on and tight; but confirmation is always good.
