Which diameter brake disc?
« on: January 29, 2016, 09:14:32 am »
Morning everyone

I'm looking to order some front discs but have no idea which of the following would fit my 2005 AXX engined car (from GSF website - they have 33% off this weekend):

312mm diameter
288mm diameter
280mm diameter
345mm diameter

They have PR numbers next to the different types - like 1ZE, 1ZP etc - is that anything to do with my VIN number?

I can't measure the diameter without stripping the disc off either and need the car this weekend.

Thanks for any help......

You can find your car's PR codes in a stamp in the boot floor or on your car's manual. You can then use an online PR decoder to know what each means. :wink:
