Brake upgrade 'How to" - Page 4

I dont see your problem.

I used all oem mazda parts and is cost next to nothing over a simple brake job. I do plan on tracking the car next year but even if you don't there are other benefits. Under identical driving with comparable parts having larger brakes decreases wear and tear on pads and rotors meaning they'll last longer.

So 15 inch wheels will fit this combo? Can someone relist and confirm what parts are needed and work for the MX-6? After reading through these pages, Im somewhat confused as to what to order. Also I assume the brackets could also be ordered- correct?

You need everything, brackets, calipers, rotors, pads.

Ok. So I should quote everything from a 99 626 then- correct? Also I suspect the caliper pins are also from a 99 626?

Yep, I plan on doing this swap, hopefully pretty soon, and I'll probably get everything new/remanufactured from Rock Auto.

Thats proabably the simplest way to do it.

Does any one know if the mx6 stock 15" rims will fit doing this?
Approx. how much larger is the diameter of the 99+ 626 rotor, front? Looks from the pictures to be about an 1" to 1.5"

**ls six** · 2-5-08, 20:49

Yes the 15's fit fine. I'll be editing the original post soon with more solid info. I measured the rotors with a tape measure and it's not the best way to measure rotors.

So I'll be posting catalog specs when I find them and defining exactly what one will need for either a complete swap or a partial swap.

I'm also doing a 2 piston upgrade to compliment this mod and then I think this thread can be moved back to the projects forum. If we wait around ti'll all the possible combos are worked out it'll take forever lol. I still think the Speed 6 brakes might be posible but those just aint available right now.

hi guys im researching a brake upgrade for my mate who doesn't get on the pc much and when he does doesn't know where to start

is there any other larger brake and calliper combos that fit well another mate had Rx7 calliper and rotors priced to put on but that needs an engineered bracket to make the callipers fit and was going to cost $1100 au

i was looking @ the DBA website and came up with a spreadsheet of comparable sizes for what the MX6 runs but have no idea about callipers if the callipers from aforementioned cars would fit

any thoughts will be appreciated

Nothing that would cost less than $1100.

The above brake setup with Subaru legacy 2 piston callipers and slider pins would be doable. I cant say the suby calipers will fit for sure till i do it my self. As far as I know I'm the first to use them on a seccond gen.

Mazda 6 part's are still a possability but unknow as of yet.

After market kit's for the 3rd gen 99+ protege will fit but start around $1500.

Madaz_Rx8 · 2-16-08, 16:39

$1100 was to engineer and make safe to the standards of our ADR (Australian design rule) at least I'm guessing that's why it would of been so dear.

in that spreadsheet i posted for the up sized rotors the biggest difference is the Central Hole Diameter what is that? and if he was to say use the big Rx8 rotor how different would the callipers be i know a spacer would be needed to adjust possibly for bigger rotors

The central hole is the large hole directly in the center of the rotor hat assuming your talking about 1 piece rotors. It shouldnt matter much as long as it clears the raised portion at the center of the hub but get the closest match posible. You could machine smaller holes to be slightly larger but dont remove too much.

Do the RX8 rotors have the same offset as ours? What about max thickness?

It cant be thicker than ours or the stock caliper wont fit. Thats why the millenia rotor wont fit despite being (about)the same diameter as the 98+626 rotors.

The available kit,s for the GE and BJ (3rd gen protoge) chassis this upgrade and I4mx6's protege rears are the only bolt on upgrades available now.

Sucks that you need to go through a cert process for the bracket's down there but atleast you KNOW it'll be safe. For the money either get one of the many available kit's for either chassis or use my setup. I assume that aftermarket kits would need to be certified as well. Is it possible to submit a manufacturers kit to be certified? Is it safe to assume that you dont need to wory about a cert for installing non stock OE part,s?

Mate, I've been up down around and all over the RX7 4-spot conversion and to do it here in Australia in a manner that can be made safe and legal (certified by engineer for ADR) is basically stupidly too hard to get something that works and is practical.

You can't swing more than 314mm diameter at 22mm thickness in the RX7 calipers, there's no common/cheap rotor that works in them. The calipers need almost 70mm to clear from the rotor surface to teh wheel spokes etc etc.

They are just hard work.

Instead I've switched dev to using PBR Twin spots (Commodore VE/Pontiac G8) on 330mm Mustang or a similar Falcon 330mm. These give wheel clearance, can be mounted much easier because there's more room for the bracketing due to very different mount ear spacing and are common/cheap.

The adapter brackets are being done in CAD to exactly match the PBR moutning requirements for locatign the caliper over the rotor, and will use factory fasteners and materials required for certification.

Cost is still up there but under $1K for the fronts, but it's a far more robust and simple design that will work under 99% of wheels and the PBR twin pistons are actually very very efficient.

A 300mm All VE based setup would cost about $500 with new calipers and rotors and pads and the adapters. But you do need to do some machining and re-drilling. Depends on the facilites and location of your mate really...

Once we've gt a couple fo setups made up I'll post pics and costs to see if anyoen else wants them (I'm working with a mate, hence doing two sets).

Yeah I've looked at what other people have been trying to do with the rx calipers and Im not impressed. They all require some custom work.

Somone on PT was supposed to offer a kit using 7 calipers with subaru rotors using custom alloy hats. He hasnt responded in some time so that means working out the rotor would be up to the individual builder.

I have painted calipers, that turned my car into a Lancer_Slayer! For real!
