Floating discs mate, until you get up to a reasonable speed the discs will move about on the bobbins and rattle against the bells, until the rotational speed holds them still.

Nothing to worry about mate

Thanks guys!

One less thing to worry about!!

They usually stop rattling if you actually use the car properly and the elongated holes on the discs or bells fill up with brake dust, and dampen the sound of the rattle.
If you do not have rattlers, you will usually end up killing wheel bearings instead.
If you have rattler, they need more maintenance to ensure they do not run out and cause uneven wear, and disc cracking as the bobbins can wear and break
You can run 380mm non floating discs

seems like a crappy thing .with them floating discs....dont want them anymore..but you did say you can run 380mm non floating?

cossymad

Yes you can...well 378mm to be precise, which is what most of the AP kits are in fact.
It is a simple case of swapping the discs, if it is a 'float in the disc', or swapping the bells if it is a 'float in the bell'. If you get me!!

okei..cool
cause i will get bigger brakes for my car.and it has to be some big brakes i think..just for the look..cause my standard brakes looks fookin tiny behind my 19 inch wheels.and yeah of course i want better stopping power.though i dont need 380 mm to get better stopping power..but i might as well go all the way to 380mm ..or maybe settle with 356..
