i like it http://fsae.com/groupee_common/emoticons/icon_smile.gif had a thought along those lines a while ago. think i might get some laser cut and test them against traditional floaters. id be worried about the fatigue resistance under cyclic heating, direct tension and bending of those stainless steel strips http://fsae.com/groupee_common/emoticons/icon_wink.gif

Yeah I've had a bit of a play with these things and i reckon they look like they're designed to generate pad knock off.

i was interested to read in the marketing blurb that they claim to reduce it.

Paul, there is no radial torque to push the pistons back.
It's a 50+ year old idea used to hold the driven plate in diapragm clutch pressure plates. suprised no one has tried it before. ultra reliable except they don't like torque in reverse direction. I guess you only use them on the front. (what have you done with the RX7?)

you'd have to pretty stupid to run them the wrong way! http://fsae.com/groupee_common/emoticons/icon_smile.gif and why only on the front? the concept obviously wouldnt work for a sprocket (or sproter).

im also not sure how they prevent knock back because the elasticity of the metal strips would force the disc back to the centre unlike a true floater. any other thoughs. would this offer any cost/design advantages over conventional floaters. i.e. would the judges like it or is it a case of different for no reason? (in FSAE context) i personally think, having given it a bit more thought conventional floaters are still the way to go. convince me otherwise?

Interesting, I saw this on a V8 supercar the other day and was intrigued. (Note: V8 Supercar is an Australian thing for all the non Aussies)

I was told that it helps self alignment of the rotor, it would be interesting to hear people's thoughts on it. I don't really thing these guys would do it without good reason

No they don't generate any torque or force in operation that would push the pistons back, but they are free to float and bang around sideways quite a bit, more so than normal floaters that have a defined amount of float. I belive that with normal floaters a limiting factor when it comes to deciding how much sideways float to incorporate is how much they'll bang around over bumps and things and push the pistons back.

Bryan, got the RX7 going again a few months ago with a second engine of the same type but 13B external bits. But we're going to melboune in a few months (I'm working for Perkins) so it will most likely be for sale as will the NSU that I've been babysitting for the last 2 years. Know anyone who would be interested in an excellent RO80? original motor too.

You would have to be pretty stupid not to realize what happens when the brakes are applied when the car is travelling in reverse!

yeah, slamming the brakes durring a spin might not be so good for these discs...

i have a brain http://fsae.com/groupee_common/emoticons/icon_confused.gif
*retracts statement and crawls back into his hole*
fsae cars dont have a reverse gear. as to spinning, thats an issue. has anyone had problems with floaters after a spin?

[Eric Wort]

Actually, it looks like the straps alternate such that they can take a load in either rotational direction. They do sell these things as streetable replacement discs for EVO's and STI's.
