I tried searching for it on google but had no luck. I was just wondering if anyone knew the size of the hub on the rotor. for a wrx.

 

like the circumfrance? or bolt pattern?

 

 

so you mean bolt pattern, or the circumfrance?

bolt pattern is 5x100

 

I think he means the circumference/diameter of that circle inside the wheel studs.

 

I think the rear brakes are the same on the wrx as the RS, I know the fronts are different...not 100% sure about the rears, though. Anyhow, if the factory service manual doesn't have the measurement you need you'd probably need to measure it yourself I guess? what's the measurement you need for?

 

The hub bore is 56mm. I think that's the measurement you're looking for.

 

its 60mm on a vw also.
