As the Title Says.
What is the Dimensions of the Factory Brake Discs Front and rear for the Mazda3 MPS/MazdaSpeed 3
I have Searched Google so far to no avail... I need the Specs to ensure the Parts Shop can get me the correct sizes.
Mazda Prices aren't Horrendous.. but when you can get parts like that at cost... why would you bother paying Dealer prices...
are you going for like different brand rotor? There are numerous brands out there but maybe even shoot MPS Garage or the boys at GSL an email, they should know the sizes.

My Uncles run one of the bigger parts Distributors in new Zealand
so consumerables like discs and stuff i can get at a very good rate..
Im likely to end up with a brand like Zimmermann or Brembo
i have been quoted from mazda Front Disks beign 500NZ Dollars + 12.5% GST
for Factory Discs... I'm likely to be able to lay my grubby hands on some brembo or zimmerman for a quarter of that...

Read the brochure that you probably read before you got the car!
It states (Gen 1 MPS3) F 320mm ventilated & R 280mm solid (Gen 2 details are the same, according to the below website).
For those interested in the comparison, the MPS6 (2005) brochure states F 320mm ventilated & R 314mm solid.
If I'm wrong, blame the brochure(s).
You can't have Googled too hard! In my 1st and only query "Mazda 3 MPS brake disc diameters" I was swamped with answers that all match the figures I have given, including Mazda's own website, see http://www.mazda.com.au/Models/Curre...fications.aspx under the "Chassis" tab.
Gawd!

Thanks Guys i googled my ass off and all i could find was Gen2 Sizes i wasnt sure if they were the same
However..
The O.D. of the Rotors was the easy part.. thanks to mr GSL he has posted what looks like the OD of the Discs and the Width of them (the width is a pretty important part also..
the good new is
I can get Front Discs and Rear Discs off the Shelf from Mazda for
Front - NZD236 + GST (12.5%) Each
Rear - NZD118 + GST each
from my uncle
Front - NZD120 + GST each
Rear - NZD10 + GST Each
Seems like a prett obvious Call
I can get 4 slotted for 100 cash so i still come under the price from mazda :P yus!
then again i should probably get a quote from the local DBA dealer....
