Re: Anyone interested in Cobra adapter brackets
 

My concern is that the width (or height in the above pics) doesn't cover a lot of the square area of the Cobra rotors, even though it grabs the correct end (the outside) for proper leverage. I'm basically looking for the calipers that have the most pad surface area and use the Cobra rotors.

Re: Anyone interested in Cobra adapter brackets
 

Yeah, that is the weird thing with them. However, that is how they are on the mustang from the factory so I can't imagine that there would be any issues with them being like that.

Performance wise, think about it this way: More of the 'meat' of the pad is concentrated at a larger radius from the hub centerpoint, and therefore will have a bigger impact on brake torque. the pad material near the center of the rotor isn't as effective. The cobra pad doesn't have any material that comes to the inside edge of the friction surface, but has a 'long' pad that covers a larger angle of the rotor and at a larger radius. I think this would give you pretty good braking torque.

down side: it looks weird. And the evo/etc pad probably lasts longer due to more overall surface area.

Let us know if you find something else!

Re: Anyone interested in Cobra adapter brackets
 

Pad thickness/volume also matters for heat dissipation and how long they actually last.

Re: Anyone interested in Cobra adapter brackets
 

That's true. The 'stang pad is thicker but the evo pad still wins the volume comparison.

Oh, one other factor to consider: when you go to the parts store and tell them you have a mustang cobra, you actually get respect from parts counter dudes. As opposed to the eye rolling response you get when you ask for mitsubishi parts :D

Will Cobra brakes fit under 16" wheels?

Re: Anyone interested in Cobra adapter brackets
 

I'd be quite surprised.

Re: Anyone interested in Cobra adapter brackets
 

They don't with any calipers I've seen.

Re: Anyone interested in Cobra adapter brackets
 

If you're trying to keep things cheap, I think 17" OEM 2G GSX wheels go for pretty cheap. I got a set for $50 recently..

Basically what the production version will look like. Machinist recommended increasing some radii so I had to change the design a hair to make it more manufacturable.

Also this one is about 25% thinner. Final piece will be made starting with 1" plate, this one is about 0.75" thick

Re: Anyone interested in Cobra adapter brackets
 

Any price estimates yet?

Re: Anyone interested in Cobra adapter brackets
 

Looks really good.

Re: Anyone interested in Cobra adapter brackets
 

I wanted to hit $50 per set, but i'm not going to be able to.

If I can make them with 6061, they'll be $75 a set. Need to do some strength calculations and simulation before I make a decision.

Re: Anyone interested in Cobra adapter brackets
 

Sounds good. Keep us posted.

Re: Anyone interested in Cobra adapter brackets
 

Will the hardware specs be included? This is a good bit cheaper than the RTM brackets.

Re: Anyone interested in Cobra adapter brackets
 

Well RTM includes brake lines, hardware, and the hub ring.

I figure people are capable of getting brake lines... I could include hardware and I'm looking into the hub ring situation. I guess there are 2 different sized hubs but should be a simple lathe operation on some aluminum tube to make those.

Re: Anyone interested in Cobra adapter brackets
 

In the article I wrote I included the specs of the hardware I used. That was of course with the RTM kit but should give you a pretty solid starting point. I even included where I got my brake lines from, which I shared with RTM so those are the same exact lines you get with their kit as well.

Re: Anyone interested in Cobra adapter brackets
 

I'm looking at reducing the bracket thickness... might be excessive and that will bring material cost down. Should have an update this weekend.

3D printed prototype is 0.8" thick

Re: Anyone interested in Cobra adapter brackets
 

Go figure, 6061 doesn't like heat. Design change pending.

Re: Anyone interested in Cobra adapter brackets
 

If you want me to, I can check at work what a good AL would be for this application. Halon and I work with a zillion engineers, and I know of one who is a metallurgist & weld engineer as well.
