930 floating front rotor assembly - how??

[dickster]

i want to attach the rotors to the hats, i have all the right bits but don't know what to do with them

its not that obvious looking at them....

anyone got pics or diagrams, or instructions???

cheers

uh, I am not sure how to answer. The dogs are bolted to the hat with the rotor between. Sort of. Then the hat is bolted to the hub. I don't have a pic. I did it before I had a digital camera. The rotor rides on the dogs loosely.

dean,

thanks, i think i've finally worked it out. only the dogs don't fit in the slots in the rotor

i have emailed doug at vci for advice.

Does this help?

[dickster]

morning nick!

thanks, but no, not really, i have only a two piece assembly.

i think i have a problem with the "dogs" as they don't fit the rotor (disk!). these are oe rotors as well, so i am a bit surprised.

cheers

Dickster, are you building a track car? VCI and Porsche don't recommend floating rotors for the street. The rotors make a lot of noise as they move on the hats.

[dickster]

both track and street.

to be honest its not an issue for me. my everyday transport is a sports bike, so i only cover around 5k in the car per year.

i'm used to the noise of floating rotors from my bike.

it was too expensive going non-floating. this way i get to use the std 930 rotors - which btw were floating!!

its a pretty uncivilised ride anyway, so it ain't gonna make much diff!! i don't think i'll hear them over the muffler.

cheers

Hey Dickster

You can file the slots or the dogs a little to make them fit.

And don't worry about the noise from the floating rotors. It's a bunch of hooey.

Only the '78 and '79 930 rotors are floating. Any chance you were sent the wrong ones?
This a picture of my VCI floating rotor setup with Porsche floating rotors. I'm not sure how the rotors are fastened on a factory setup but I thought this might be helpful. My floating rotors go "clomp clomp clomp" at low speeds. It isn't bad but if you let someone borrow you car be sure to tell them about it.

Those floating rotors seem like a good idea. However it seems that they would wear as they "float" on those little rectangular retainers, eventually getting sloppy on the hubs.

Perhaps the wear rate on the rectangles is slower than the pad friction surface, such that the rotors are replaced before it becomes significant?

Do you guys with floaters notice "looseness" over time?

what a pita! but thanks for the advice, i'll probably have to.

chris,

no, the correct ones! thanks for the pic - very useful.

chuck,

i don't think there is an issue. they're pretty std issue on sports bikes these days.
