Hi guys,

Just recently I have been looking into changing my rotors out for DBA 5000 street series and was out measuring my rotors and found they are:-

Front - 320mm diameter

Rear - 310mm diameter

The calipers have PBR written on them, and from a little research I believe stock rotors are meant to be 298mm? Might be a stupid question but are these upgraded brakes, or do these cars come standard with PBR calipers + this size rotor.

Also the calipers are silver not black or red.

Cheers John.

Might be a good idea to take a couple of pics to clarify what I'm talking about.

Wow bigger than front?

What has got me stumped is that my sizes are different to everywhere I look. I will try and measure again tomorrow because I want to go and see about new front rotors from supercheap, since they got a sale on $120 for dba slotted rotors (I think they are 5000series).

Also the car is a BF if it helps, maybe they went to bigger size from ba to bf?

Just found this. It was quite a help. Again, I will double check the sizes tomorrow. From all the pics I am seeing of pbr upgraded brakes, they look nothing like mine. My rotors are not slotted, my calipers arnt red, and my front rotor thickness measures about 28mm (unless I am worn down to an illegal limit :/)

The pbr upgrade brake rotor is 325mm x 32mm thick. You have std BF turbo brakes which are 322mm x 28mm and are not interchangable with the upgrade calipers.

No you go in and ask for rotors to suit std bf turbo , slotted or not up is up to you but it will be 322mmx28mm because that is what size they are.
