Brake Kit

I wanted to put this here so we can try and get enough interest.

The kit I would like to offer will put 88-91 Rx7 4 piston calipers and rotors on your repu. The spindle I have based this on is the pair of 1974 spindles I have. I am not sure what years this will cover.

You will be able to use either the 4 lug or 5 lug hubs. If you go with the 4 lug hubs I suggest you still use the 5 lug rotor by re-drilling it with the 4 lug pattern.

I have the two major parts of the kit prototyped for fitment checking. I will be able to give more information in a few days about offsets and stuff.

If you would like a kit during this set, please respond here. $150 each up to 5 kits, $125 each for 6 or more kits.

What a shame...

...retaining the proper, stock, 6-lug is not an option!

For those of us not looking to mix-and-match bolt patterns front/rear, and not ready or willing to re-do the rearend at this point, sorry it's not an option...

Sounds way cool, otherwise!

If you can redrill for 5 lug, why can't you do the same for 6 lug........... I would consider that option.

I'm game for the brake kit

5 lug is okay, T][ bolt pattern is very common. Curious what backspace I'll need to make it fit.

It would be great to have a T][ 5 lug rear kit too. But first things first, I really need bigger front brakes for auto-x and I may take REPU out to Mazfest this may for kicks and giggles!

I bet you could take a 4 lug hub and fill the stud holes with WELD, then drill and spline new 6 lug holes. Press in new wheel studs.

sorry... can't go the big brake route now.. spending way too much money on a monster engine to spend more on brakes, and new rims and tires.

Sound do-able, count me in. I have the monster motor now need the brakes to slow the *%&#$^ down.

no one else wants big brakes?

Doesn't anyone else want less brake fade and shorter stopping distances?

big brake kit

I'd have to stike with teh 6 lug also. one more of the unique things about these. do like the idea of the RX7 parts. maybe switch bearings at the hub back to six lug?

by the way, did rasyrx7 find a truck yet?
might have one in boise.

Time, Money, Work...

...'priorities'; sorry.

Choice of 'project' REPU's 'potentially' (still) available from your's truly... all '74's, none with running motors... (and not my 'best of', either.)

That said, if I happened to have bits you want/need, and could trade for a big brake kit... I'd be all over that!

I love to barter. Mainly cause I am cheap :)

Thanks for the offer. Most of the stuff I need are hard to ship items though. Fenders, Tail gate, hood that kind of stuff. I could use a set of tail lights though.

So

Billy, do you think ReSpeed could also offer a 6 lug hub for our 6 lug friends here?

And does anyone know if a Turbo ][ Brake Master Cylinder will fit REPU?

6 Lug?


In order to do a 6 lug we would need to find a hat style production rotor that is around 11" diameter, .870 thick with the 6 lug pattern.

If that is not obtainable then we would need to design a hub and rotor top hat for an aftermarket rotor. This is when we start looking at cost going up. Now we are talking about a complete custom kit like what started this thread.

My vision for our big brake kits is for a low cost solution using production parts with some kit specific manufactured parts.

production based 6 lug rotor

Okay,

I searched brembo's website here:

http://www.brembo.com/CatalogoBrembo/Templates/SearchGray.aspx?NRMODE=Published&NRORIGINALURL=%2fENG%2fMarket%2fCatalogues%2fSearchCars%2ehtm&NRNODEGUID=%7b17D7BCC8-5414-40CA-9D35-30F3CABF4BA3%7d&NRCACHEHINT=NoModifyGuest

and found one 6 lug production based rotor that may be worth looking at.

5/86 - 95 Mitsubishi 4wd truck and 89-91 Montero front rotor.

Pic here:


Concerns I have are the swept radius is 1.7mm less than T][.

Would another option be to use REPU hub and bearings, make an aluminum adaptor for hub to rotor, and use aftermarket rotors & calipers ala wilwood or outlaw? That way we could keep 6 lug but it would bump pricing up. On the other hand, some wilwood parts are pretty cheap on summitracing.com if you keep searching....

I did run across that one as well. Diameter and thickness work out great but it does not match the repu bolt pattern. The 22 mm thickness lets us work with the 4 piston calipers that would be less expensive than aftermarket ones. On the right track though.

http://www.discountedwheelwarehouse.com/Mitsubishi___Vehicle_Bolt_Pattern_Reference.cfm shows it's the same wheel bolt pattern as REPU 6 x 139.7mm

Mounting Pattern

I have looked into it further. That rotor looks like a good fit. We would need to do special hubs to mount them. On a one off project - someone could have the mounting pattern of that rotor re-drilled to mount to the stock repu hub. Not a good idea for a production solution though.

If we were able to offer a kit with aluminum hubs, laser cut caliper brackets, pair of rotors, and the hardware would anyone be interested? Rough numbers would be aprox $550 for the kit. Customer would supply the 4 piston calipers and new wheel bearings.

Aluminum hubs dissipate heat much better than steel too, very good for towing or the few of us who auto-x. The front T][ 4 piston calipers are $37.99/each reman. with hardware + $50/core @ Kragen.com. With custom built hubs the wheel mounting surface could be engineered to be in the same location as stock, thus allowing use of the wheels you already have.

Would ReSpeed give us specs on stainless steel brake hoses & fittings, so we can go to local Earl's Plumbing and have a set made up. Or would you consider supplying them with the kit and bumping up price accordingly?

Although 5 lug rims have *many* more wheel options, if 6 lug is the way members want to go that'd be cool with me. I kinda like my white steel wheels.

so do we have enough interested people

to do a big brake kit using 6 lug hub and mitsu rotor?

I'd love to finally get real brakes on my REPU.
