FC RX7 and NA MX5 Hub Dimensions?

chewyryce · 27-01-2011, 08:05 PM

Does anyone know the dimensions of both sets of hubs? im trying to do a 5 stud conversion and was wondering the dimensions of them to see if i can machine them down to size. main reason for this is for larger brakes.

FC or FD RX7 dimensions would be great.

The hubs won't work with FWD.
If you're after the disk dimensions then look at the DBA online catalog.

and with that little bit of info.

there are plenty of bigger brake options available for MX5s. no reason to change the hubs.

IF you wanna go cheap, something like NB8B calipers with slotted rotors will bolt straight on. they are 270x22mm.

Without knowing which NA you have, you will gain from 235x18mm (NA6) or 255x20mm rotors (NA8).

I remember seeing once that fc calapers had the same hole/bolt placement as a v6 ba astina caliper.

yeah i was after a larger brake upgrade/conversion due to more power that will be added to it. i want to be able to stop before any more power is added. i'd have to explain the mods and what not eventually but i dont want to spoil it until i get the car.

haha don't spoil it. MX5 power mods are no new news to some member on here.

do you know much about MX5s? i am a unemployed bum currently, so i have some free time to help out.

lots of peeps have done the NB8B front brake swap and raved about it. worth a look in to.

or i'm currently looking at modding some wilwoods from a MX5 to suit my Astina.

forgot to ask? NA6 or NA8? MY?

chewyryce · 28-01-2011, 08:32 AM

cool. would be great if anyone would want to help. i have a hoist and what not ready too

. um i think with what im going for i'll probably need more than just NA8B upgraded brakes... HAHA

chewyryce · 28-01-2011, 08:34 AM

ah yeah.. about that.. im not sure :P. i was too caught up with what he's put on the car that i didnt even look at what model it was. all i know is that its a eunos roadster with removable hard top. nothing more that i know
