quick 5 minute rendering

i need the correct diameter of the holes tho

Brain needs some help with his dimension layout. :)

haha yeah it was very hard to follow, but props for him for going thru that .dwg file cause i sure as hell wasnt going to.

i have 2 exams im studying for right now but if i take another study break ill neatly dimension that and put it on a nice layout

factory dia 10 mm bolt dia for the caliper bracket.
7/16 (.4375 ) for mounting bracket to spindle.

M-tuned, any idea when this prototype kit might be ready? Do you have an estimate as to how much it would cost? And what other parts would we need to source?

We plan on making it so you ONLY have to buy Rotors and Pads. I think initial hope was in the $75-100 range for brackets, hardware, and aluminum centering ring.

Dats wut I'm talkin bout. Yeah boyeeee! :bigtu:

Awesome, get it done! We'd probably have to get a maximum ID for wheels, so there's no clearance issues.

That $75-$100 is for the front hardware only, correct? I wonder what it would take to put the 1.8 front rotors onto the back...

where do i sign up? :)

If you guys don't get er done I will. I can beat his price, probably in the 50-75 dollar range for the fronts. Maybe front and rear for a 100 U.S.D. Monday I can look into it more. I want this kit for my car and can't justify manufacturing just one.

B.T.W. this design probably needs some refinement. I found critical stress points with my analysis that makes this unsafe for some braking conditions. The last thing you want is an ejected/dangling caliper at 100 M.P.H. that makes your foot sink to the floor.

M-Tuned, too bad it wasnt available 6 months ago...

Travis, great - design them up... do I get a free set for being the OP? ;)

do it travis, compition is always good.

I'll hook you up, can you test these for me though? We're talking tire flat spotting madness :giggle:

Travis

how much shipped to holland?
I'd be in :)

Free shipping group buy on the FM Wilwood proportioning valve kit to correct all the front bias we're gonna have once we do this swap.

I'd think the brackets would cost almost nothing if they were lasered out of mild steel, 100 at a time. You could rough the holes with the laser, put them in a really simple CNC mill and get them perfect in about a minute per part. With the right tool, maybe even put in a slight countersink to allow more bolt head height.

Seems like you could use two brackets per side, sandwiching the ears on the upright. Then use spacers and shims between the brackets where the caliper mounting bolts pass through to match the thickness of the ears. The ears are generally not a precisely controlled thickness, as only the caliper mounting surface needs to be controlled relative to anything else, hence the need for shims. This would significantly increase the strength of the system (especially relative to the bending moments) without changing the z-axis position of the caliper or requiring a lot of fancy machining.

i REALLY want me some.

Why are these not the same?

I've had a set done, but was not ready for mass production. We are ready to go with these but are doing a few things a little different so no grinding of bolts is required etc.

Here is a thread with more details for all of you..
