actually i just want to see it perform mid - end of july on a 6-8 hour autox day the 60-0 only applies if the same tires are used on the stock setup, man these look sweet and what all comes if with if we buy this kit

i'd do this kit - whens the deadline for payment? how much, etc etc

The reason I made this was not for 60-0 or 100-0 stopping times. I made this kit so that brake fade is no longer an issue. Stopping times will be mostly dependent on the tires, not the brakes. They should stop somewhat similar to the stock setup with very aggresive pads. Not only do they save weight vs. the stock brakes, they look cool as hell to.

In order for these brakes to work at the maximum, you should be using hardware from the v-6 model braking system. Rear pads/rotors, booster, and 15/16 master cyl.

I'll let everyone know my driving impressions in the near future.

ding!ding!ding! and we have a winner! exactly why i'm upgrading mine, well that and the car added a lot of weight / power to the wheels in the rear so i need all around upgrading

just a thought ,the major problem seems to be connecting the wilwood calipers to the spindle.
If enough people were interested then maybe we could get a PROPER spindle cast.
I did do metal casting when I was at uni so I know how its and a foundry where they do this sort of thing wouldn't have any problems making them and as a bonus we could request they were made out of 6061 aluminium.
chances are they would also be able to finish the product in-house as far as machining goes.
I have no idea what this would cost but might be worth someone asking.
putting on the wilwood brakes would then be no problem.
if its to expensive to get done in the states maybe china.

I'm pretty sure there sand cast so we don't need to have a large order maybe 20 or so

my first instinct is to drool over the above idea but what about durability? the cast iron seems able to deal with stress and bumps better?

cast iron is cast in sand the aluminium is just an option but if were going to go to all this bother then it might be worth looking into, and I'm told that 6061 is one of the hardest.
I'm in Australia so it wouldn't be as cost effective to get it done here but artist use foundry's all the time for sculpture and many colleges in Australia have small foundry's.

I'm sure it would be similar in the states.

It may turn out to be dead end but I think its worth someone looking into.

it would be far easier to design, draw and machine a workign adapter for the existing spindle. If I had the parts on hand I could probably have something drawn up in a few days. There would be two brackets, fronts and rears. There would likely be a slight modification to the spindle like cutting off the existing mounting tabs, drilling and tapping holes for the new bracket. This is off the top of my head, but if a simple bracket could be drawn up I could have them made by one of my suppliers. Cost is dependant on the complexity fo the bracket and how many machine operations would be required. If I was ordering 20 cars worth I think it would be reasonably affordable.

I believe I could make the calipers bolt on, possibly with no mods, but definitely with some moification fo the spindle. Anyone want to ship me their calipers? I'll ship em back.

That is a cool idea about making a new spindle and the I've thought of that as well. One problem is the cost of making one out of aluminum would be very expensive. It would cost much more than I would want to spend just to mount Wilwood calipers. You can buy a bigger brake kit that uses a bracket for the Mx-3. It cost's roughly $1500-1600.

I took these spindles of mine to a machinist and he did exactly what I wanted. The knuckle has two holes for mounting the stock caliper. Around the top hole, I rounded off the edges. The bottom section was cut off about half way and from there, a new machined piece of metal takes it's place. The machined part is held in place by 2 allen head style bolts. Part of mounting this, he had to drill the new holes and countersink the holes. After the machined bracket was in place, the rotor, caliper, and pads then all were mounted up. From there he had to resurface and re-measure the machined piece to center the caliper. Remember, these are fixed calipers, not floating, so aligning it is part of the final installation. The calipers are shimmed with several washers so that the caliper was centered on top of the rotor. Both of my modified knuckles are not the same however. One side uses more washers than the other. This is kind of a question mark for me but I think that one of the knuckles is bent slightly.

I can have more machined tabs made but the parts must be fitted AT THE MACHINE SHOP.

It will only work like this---Send me your knuckles and in return you get a modified knuckle ready to except the upgraded brake parts. I fear that no two knuckles will be the same. This is why you would have to send them here.

Please do not start asking for prices or when you can start sending me your knuckles. I'll post up pics tommorrow of my modified knuckles. I still have not worked out a few things with this project...be patient.

so I think we all agree that unless your willing to get new spindles made up that you will have to cut away at least one of the tabs and drill. which is what I did anyways.
I don't know what models have what spindles but in my case it was a 94 eunos 30x with ABS and on the spindle it was marked R1 EA03.
I would have preferred a new spindle been made up due to the legal issues in Australia.
It would seem the next step is those who have already done the mod might want to post the there patterns on the forum so that a comparison can be made with different models of spindles ,calipers and of course rotors.
It may then be easier for someone to put together a GB on the parts that need to be purchased and the parts that need to be fabricated like the bracket (dog-bone).
I can contribute some to the design but I haven't looked at the rear brakes yet and instead of buying a wilwood hat I machined the existing rotor to bolt on to wilwood rotor and I admit it was not the best option, a proper aluminium wilwood hat is better.

I still think if someone has some contacts that a simple enquiry as far as cost go to getting spindles made up either of cast iron or aluminium wouldn't hurt but if that doesn't work then as a community of like minded people a effort should be made to get the patterns online for others.

All right. I've had a small leakage problem with the brake lines but they are fixed now and the brakes have been re-bled. On the test drive, the pedal was firm and did not take much effort to slow the car down. I'm using the street pads from Wilwood, so braking is not as impressive compared to a race compound. I am very pleased with the outcome of this project and has turned out exactly like I wanted it to.

I've spent a little more than I had wanted through R&D, but that is usually the case with first time projects. I'll get a final estimate of what it would take to produce more if people are still interested. Of course, some money will go to Jeff A. from each sale to support the site if all goes well.

Great!
We really need innovators like you. I hope you make some $$ from this.
I understand about brake fade.
My setup works well, but I haven't raced yet.

sweet man this is deffinently on my to do list once the car is running. can't wait to see more info on it

wow progress is moving along faster than I thought it would!
