ID this brake rotor

Since I have a BBk set for the front I decided to look at a set of "spare" stock front rotors I bought last year. A just in case set. So I open the box and the hole spacing looks pretty small. I measure and it is 4x77-78 range.

Any clue what this may go to?

Hi,

the rotors are bolted to the back of the

hub in a smaller bolt circle than the wheel

studs. i don't have a set to measure but i

think you got the right parts.

yes you are right..big stupid DUHHHH on my end. I was looking at the floating rotors from the BBK and I forgot the 02 rotors are not floating

Everyone feel free to flog me as I deserve it

Don't feel bad - I made a mistake once in 1948 in Jamaica. :-)

Marshall I am most likely using the incorrect nomenclature. I have 320 hubs and vented rotors for my brake upgrade. The 320 rotors fit right over the 320 hub and have a small allen headed screw that holds them in place. So they are not really secured to the hub like an 02 rotor is. So I refered to them as floating because that is what I thought a floarting rotor was.

What is the correct name for the 320 setup?

just regular vented rotors. basically almost all cars made after the 2002 use this style of front rotor.

floating rotors are a high end/race part that mount the rotor disk surface independently (float) of the rotor hub to allow for expansion/contraction due to the heat generated. e36 M3 rotors are example of this. US market M3's got normal vented rotors. euro market M3's got floating rotors. i have the euro rotors on my e36 M3.
