i have a v6, i have the std rotors and the higher end lucus pads, and when i go for a sprited drive now they only last about half way on my usual route be for they are smoking and not biting any more, this is with std power and a fair bit of suspension work, the power over the next few months will incrase, so this will become even more f a probelm.

twilightprotege has the series 4/5 calipers on his BJ but he has to get custom mounts and rotor hats made.

The jewel in the crown of mazda brakes is the Rx-7 (have not looked at the Rx-8 yet).
For a FWD conversion I would seriously look at the Eunos 800M setup.
The 800M struts my just fit without too much trouble, give it a try.

May I suggest a different parts bin. The RX8 big discs may well be more dimesionally accurate for the 5 stud wheels. At 320mm the correct stud pattern and the same centre bore and disc line you can't really go wrong!

Calipers are a bargain! I hear (thanks to ROB80E) auto Lasers carried a bigger M/C than the manuals which may apply to the Astinas as well. That woudl give good results. You woudl need to swap reservoirs etc across. I'll check the KJ Laser manuals today (Astina silohette) to see if that remains true. Otherwise an FD Rx7 M/C is the go.

For the brackets make sure you make the locate the calipers in the correct radial location. That is based ont he same centre circle. They can be mocked up using plywood etc for best fit before having machines or simply cut from heavy guage steel. I've heard of people doing it with a hacksaw.

Lynx being FWD woudl love the hubs for testing purposes at least. My goal is to find a 4 stud hub solution similar to what you're doing. If it works on the Laser/Astina I want most of the hardware also on the MX5 for convenience.

They're the exact same looking setup between the Lynx and MX5. MX5 SP is same as any post 2000ish (projector headlight) MX5

MX5 discs and caliper brackets + pads woudl probably do the job

Brakes are things you don't really want to mess with. Get it all wrong and it can kill you.

here is thread with pics
http://www.ozmazdaclub.com/forums/sh...ht=race+brakes

my custom brakes on my Mx-6.


if you want the standard look the smart option is
do a full hub and brake conversion from a V6 - best place to get all is buy a whole smashed BA v6, take it from me you buy the car $500(say cheaper or more so ) you take waht you need sell off what you don't and you can actually make money covers your tow costs etc. Not only that you know it will bolt straight onto the car.

I've done it for Vt -to clubsport upgrades, my own MTX conversion, a Supra upgrade and still plans for some type honda - friends got a motor need a donar car to do.
Thanks mate, most helpful pics

Aaron,
Sorry thought you were asking about this for the MX not for the Lynx.
As for the RX8 rotors would be ok if you wanted to use the standard calipers
but I would prefer the thicker 28mm so I can run the twin spot calipers.
If you wanna go that way then look at the ford focus ST170 rotors 300mm
and 4 stud. With stud pattern ford/mazda should be the same 5x114.3 so
the cobra stud should be fine.

Finally you confused me about the SP turbo rears. The Lynx doesn't have
276mm rears does it ???. Another rotor I have been looking at is the Cobra
rears 300mmx35mmx19mm. How cool would my astina look if I scrored a
complete cobra front and rear setup

Nah the Lynx rears and the Asina rears (disc) are the "same" - and the MX5- "looks' the same with only the disc size being different.

I'll do some swapping...

Both the MX5 and the Lynx are 4x100 - with the disc geometry being very very similar.

VT calipers are also useless...been there tried them after the RX7 ones. Unless you go a bigger rotor than the MX5 one (270mm), they'll be too hard to mount as you can't get the caliper mounts low enough due to the shape of the stub axel. Rotor thickness differences will be a problem too.

I'm now looking at the volvo calipers (both twin and 4 spot versions), but as yet, haven't been able to get my hands on any.

OK so spill the beans what parts did you use and how much.
They look like 4000 rotors what are the calipers off.

Basically GTR, yes. V6 actually. Rotors are the 4000 series, size is 270mm.

Chicaboo, honestly couldn't tell you what the colour is now. I think orignally it was mixed as a mazda metalic burgandy, but what it was getting mixed we put more rustic pearl in it (can see it in the 2nd pic)...but i had some gun metal pearl at home, and that has also made it into the mix (seen in 1st pic).

so a 15inch for slicks can still fit ontop which is good.

I can't fit anything smaller then 17inch so it's only some race semi's for me.

It's looks DAM good but

V6 or GT-R I'm confused as always LOL

yeah mate, will still be able to use the 15's...that's the reason why i didn't want to go any bigger. Completed it tonight, just got to get a wheel alighnment, new pads and I also want to get some stainless braided lines.

The GTR and V6 use the same calipers and rotor diameter.
