Do 15" RPF1's fit over NB8B brakes?

[Kkhrome]

I have a set of 15" RP F1's and looking at upgrading my NA6 brakes with NB8B brakes and was just wondering if they would fit?
Thanks brake gurus!

According to some pplz on the good win racing site and the big forum they dont fit...

I belive some people have done it with spacers...

Are you talking sport brakes, or regular NB8 brakes?

They should fit with the regular NB8 brakes (250mm front / 255mm rear) which, as far as I know, are the same size as NA8 brakes.

The "sport brakes", as they call them on the big forum (270mm rotors I believe) may have issues and require a spacer.

Err, only the NB8A have same size rotor ats the NA8, all NB8B's have the bigger brakes which happen to be known as "sport brakes" in the US.

NA8 and NB8A are the same, NB8B are bigger again.

Only reiterating what others have said but the big forum lead me to believe that they won't fit without spacers.

Really? Wow, another thing I didn't know! When did mazda start putting the big brakes in all cars? Was that 2001 with the VVT engine?

In the states, the standard 250mm brakes persisted right through to 2005 and the "sport" brakes are a sought-after option.

Yep, Series 2 onwards got bigger brakes as standard in Aust. So late 2000 onwards till 05?

Thanks guys, I guess I'll have to get the NB8A brakes then. Anyone got a set they want to get rid of?

And at that point, NB8A and NA8 are the same to make your search easier.
