I'll drink a SakeBomb to that!

He is taking a shot at the Urge rear brake setup where you are expected to sand the brake pads to make them fit because they use a slightly thicker vented rotor.

 

Looks like a nice setup. Not sure if it was mentioned, but curious if it fits AP2v2 wheels

 

From their group buy thread

 

One of your competitors sells a rotor for the rear that is stock-sized and requires you to sand down your brake pads in order to make it fit. Your kit makes infinitely more sense.

There's three competitors actually....

I'm using one of them, and am quite happy with the solution. That said, this is pretty awesome, and I might have considered this route if it was available at the time.

However, I'm still concerned about rotor ring supply. Are you able to disclose your supplier and would we be able to go directly to the supplier if 15 years from now, you are no longer in business? I'm thinking along the lines of S2000 classic car. hahahaha

I want to have parts for my 30 year old car. I would think that a company like StopTech, Girodisc, PFC, and wilwood have a slightly higher probability of still being around, and while you guys are definitely turning out quality stuff for the S2000 (and appear to have done so for other makes represented), i'd place your probabilities of being around slightly lower than the aforementioned companies.

How about this, if we ever go out of business we'll happily publish the specs/supplier on s2ki and they'll be available for all eternity. Well... until s2ki disappears

A manufacturer like Wilwood will probably be around in 20 years but Girodisc... don't count on it. In the RX7 world, Racing Brake stopped producing a number of parts for the rear RX7 kits they sold, which we were told would not happen. Company age or size really doesn't matter, even OEM Honda parts will be no longer available in 20-30 years. This has already happened for the RX7 with a large number of parts, which only stopped production in 2002.

The SBG FD Competition rear has been in stock, and is still in stock since it was released http://www.sakebombgarage.com/sbg-co...tem-fd3s-rx-7/ . We try to keep at least 10 pairs on hand at any given time. That being said, I have to ask, don't the other kits create the same concern? Nothing is future proof, even Brembo kits but we were hoping to make this as future proof as possible by using a widely available OEM caliper, which can be rebuilt with OEM parts

 

The Urge OEM sized rotors are precisely what you are describing here and they worked extremely well to help with heat in the rear on an OEM caliper with minor modification to the OEM caliper holder. They will also still work fine with OEM size rotors up front. Running this large of rotors and pad with OEM rotors/pad size up front would not be a good time. So it is good to see people offering various options. The J's kit is similar to the Urge setup but it uses larger diameter vented rotors but retains the OEM caliper with a modified carrier, which also works very well.

Who actually makes the RX-8 rear calipers for Mazda? Any ideas?

Honestly I don't like any of the options currently available for the rear. There must be a good 2-piston caliper out there than can retain the e-brake.
