miata brakes

i was curious if any one had thought about swapping the 11" miata brake rotors to our cars what is you opinion on it......ours are 10" i think.

of course you would need to have a bracket made up but i think it would work.......come on ppl what do you think.

Acutally they are a direct swap (the rotors only). I am using Miata rotors right now since they are cheaper. They are a larger diameter and they will extend past the pad just a mm or so, but it is not a problem for the pad or rotor.
Good idea though. Interesting to see when people come up with something that was allready thought of. Then you think geesh, now I feel stupid.
I do it all the time,
"Hey guys what do you think about this.."
"well, Patrick, people already do that..."
"oh"
<now I feel stupid>

What will be the benefit of using Miata rotors, especally if you still use the stock pads? They won't be any bigger in size to take advantage of the larger rotors.

first
pat im talking about the sport package rotors.....which are 11" in diameter not 10.1" which were also offered on the miata
second.
nd4spdse bigger rotors will mean your brakes dont get as hot because there is more surface area on the rotor.....pat dont make much of a differance you could always use a wilwood 2 or 4 piston caliper but you would need a bracket for that which isnt that hard to get.

You can use the dual piston calipers from the 2nd gen RX-7..You just need to make a bracket. I've seen it done on an Escort and a 323...I wanna do it

Which Miata used 11 inch rotors stock?
Anyway, any larger rotor will require a caliper arm. Then you might as well go with a performance caliper. I've also seen some Probe guy running Mitsu 3000GT 4 pots using a custom arm.
The trick is that you have to have that arm perfectly in place or the pad will not rub properly. The caliper MUST match the rotor or you'll have different diameter set-ups and the pad will not interact with the rotor properly.
Larger rotors and calipers will mean more unsprung weight and thus worse handeling. It will also decrease your stopping power since you are then distributing the force of the fluid over a larger surface (ie, more pistons or larger pistons). The only benefit will be seen in high speed track use with very agressive pads. Even then only in the brake fade area as you will still have less force per inch on the pad.
I would suggest if you just want more stopping power that you buy some Hawk HP or HP plus. They will eat some rotors, but are a very grippy pad.
Good luck with your set-up.
If I don't find a decent kit soon I'm going to make my own Stop-Tech kit. However, I mostly race my car at real race tracks and am starting some auto crossing. The auto crosses will not be helped with larger brakes.
Also, you could get a performance mater cylinder and brake balancer to help with the loss of fluid force. Hwoever, you are now talking about alot of work and alot of money.

i can make pretty much anything that i need to make so thats why i asked....but i never thought about the two piston calipers from the rx-7..hmmmm

Pat, how much bigger are the miata rotors you're using? since you said the are a bit bigger.

how about a reply to this thread, friendster?

10.1 inches like David said. I don't use them for performance reasons as the increase is nominal. The purpose is that they are cheaper and alot easier to shop price on.
