EDIT* I sent the seller some questions pertaining to fitment of this kit, how many he has, and if this is a short term production or if he plans to sell them for some time. Hopefully I will hear back soon! I will post communication here!

[RS_OBD'oh_2]

damn. me want. me no have monies left after make car fast.
Good find man.

[onlytrueromeo]

Yeah dude, I want it too but my woman would remove certain parts of me that I would rather not live without

Maybe when I get a job sometime far in the future...they'd be for my AWD MX3 I want to build someday haha.

[onlytrueromeo]

17" rims are usually required to clear these rotors. Please contact us for a cross sectional template to make sure the wheels you have in mind will fit.

Hmm...that makes it not worth as much in my eyes...why the performance increase if you're gunna kill it by running huge wheels


A 16" wheel wouldn't be bad, although I'd prefer 15's.

OH MY GOD OH MY GOD OH MY GOD!! I wan't SOOOOOOO bad.... but the g/f would have my balls in a sling since were looking at more houses tonight..... DAMNIT!!!!!!! Though my b-day is commin up......

*watch this item*.... Click.....

nice kit, I don't think I need one yet on my d/d mx-3. Some s/s brake lines made big improvement in stopping it. Maybe when I'll make 500 hp I'll be buying that kit.

I'd rather get stuff from a Mazda RX7... a lot cheaper!!

[onlytrueromeo]

Got lots of info back!

Dear onlytrueromeo,

Hi,
If you 'd like a full size template, send me your email address and and I'll attach the file, you can see all the dimensions there.
I have had luck with some 16's, but only 3 different sets in about 2000 attempts, so it is possible but remote. The stock 16's from a gen III RX7 for example have good clearance.

I have a few kits but they are limited by the availability of a special bolt that is required for the adapter and I only have a few of those...

Would you like a kit to fit 15" rims? It will take a spindle modification, but if there is a market I'd be prepared to do a spindle exchange. Let me know what you think. Are there BBK's out there for 15" rims already?
Thanks.
Daryl.

Thanks for the response! If you can email the template to me at this address, that would be great! There are a few big brake kits available, but nowhere near this price, so most people are hesitant and will not look further than the price tag. Any other big brake upgrades are done with custom work fitting protege, mx6 or probe kits etc. and swapping hubs and sometimes axles...it can be a pain. Not many of us in the mx3 community that would be using these as a performance upgrade would want to run 17" wheels but would rather run 15 or 16" ones. What type of spindle exchange modification are you talking about? I know some people have welded/ground new pieces of steel to be able to adapt pieces from other cars. RX7 wheels won't fit as they are 5 lug pattern and mx3's are 4x100. What type of special bolt are we talking about? Is it something that can be machined for a relatively low cost? Would you be willing to sell the kits that are missing this bolt at a reduced price pending that it would be viable to get a new bolt made at a machine shop (buyers cost).

Thanks,
John Romeo

Hi John,

I'm not sure what you mean when you say "not at this price". This price is
high or low?

The caliper mount arrangement on the spindle is a typical US industry
standard. That is, the brake torque from the pads is loaded directly into
the spindle body, not the caliper as is common with most other types
(Japanese, European etc). So the caliper mount points are really token
mounts and essentially keep the caliper from falling off when not in use.
The ends of the pads butt up against part of the spindle body. This makes it
complicated to change the caliper as the mount points can't handle the brake
torque and if you just bolt up an adapter, you run the risk of losing the
caliper upon brake application which can be a bit unfortunate. The second
problem is that in order to keep the pads in check, the offending parts of
the spindle are pretty close to the OD of the rotor and make caliper
mounting difficult when using moderately larger rotors. So using the 13"
type rotors is an easier upgrade for this spindle.

To us a smaller than 13" rotor you have to get rid of some material. A few
years back I did a custom 300mm kit for a customer. Nothing was added to the
spindle as you mentioned, rather the interfering material was removed, the
spindle machined with new mount points including the mount holes and done in
such a way as to make for a proper loaded caliper installation. So the
existing mount ears are removed and new mounts drilled and flats machined to
accept the caliper.

I'm aware of the RX7 fitment, but it was the only 16" rim I can remember
fitting over a 13" rotor....

As for the special bolt, I've had them made in the past but the market
doesn't warrant the trouble. As you probably know, there isn't a line of
people round the block waiting for an MX-3 kit. I'm not sure how many I can
produce, probably another ten kits or so. When I run out I will look again
and see if any bolts are available and decide how to go forward from there.
As it is I pay about $3 each for these things when I can find them which is
pretty high for a screw.

Hope I answered your questions. Let me know your thoughts on the smaller
kit.

Please let me know if I can be of further assistance.

Thank you.

Best regards,

Daryl.

John,

Here's the template. Its a .pdf which you print full size, make sure you
select "No Scaling" in the print dialog box. Then after it prints measure
the vertical and horizontal reference to make sure its the right size. This
is not a trivial exercise, if you print the template the wrong size it will
give erroneous information. You could end up buying a brake kit that will
not fit the wheels you intend to use. Please be careful to accurately
measure the reference dimensions on the printed template to make sure they
are as indicated.

Keep in mind that we are looking for about 2 mm of clearance at the wheel
spoke, that's about the thickness of 2 CD's. If you experience interference
between the template and the wheel spoke, it's important to figure out just
how badly the caliper and wheel collide. It is possible to print multiple
copies of the template and when cutting them out, leave more material in the
area of the hub to act as a spacer. Adjusting the thickness of the extra
material on the template will allow fine tuning of the spacer thickness to
yield the required clearance at the caliper. Be sure to make any "spacer"
you add to the template of uniform thickness, that is, always add any
additional material parallel to the original cut line on the template.

If you experience a small amount of interference, frequently it is possible
to gain the required clearance by adding what we call a "wheel shim". We can
supply these in 3 mm thick and they typically do not require the use of
longer studs.

Instructions are included.

Thanks.

Best regards,

Daryl.

I have the template if anyone wants me to mail it to them, please send me an email at romeojr@clarkson.edu" onclick="window.open(this.href);return false; and I will forward it to you! Seems like Daryl is a good guy, and even though I will not be buying one of these kits at this time (no monies ) I will be more than willing to help facilitate things if other people want, otherwise you can all contact him directly.

Also if someone with more knowledge about brakes, big brake kits and what is needed wants to give me info or contact Daryl directly to help figure out the best solution - go ahead! I won't have time to research, heading into finals week and will be miserable for a good few days

This Darryl fellow is saying exactly what I had mentioned in my research. To so a 15" wheel BBK you need to remove material from the spindles.

I have had the same idea he had regarding doing a part swap. You send me your spindles and I'll send you a set of modified ones but I think I can make it so that this can be done by the end user.

[onlytrueromeo]

It would be sweet if we could have a 4 piston setup for cheap!

When I found this stuff I was super excited. Seems so long ago even though it was less than a year!
