I hammered the ever living crap out of them for about 2 hours straight last week doing some pretty harry backroad stupidity. I felt it was a pretty decent test of the braking capabilities of the car and I can say I'm still not happy with the BP-10s. My car is down at the moment and will be for a couple weeks while I wait for parts. When its back up and running it'll have at least XP-8s in the front, so I'll go whomp on it again.

Its hard because I love these brakes compared to the stockers, but I hate the pads. Blegh.

Sorry guys, I had all kinds of plans for trackday shennanigans at the beginning of the year, then I started the EFR project and its been absorbing all my funny money.

BP-10 is always a fail.

Those are the calipers I used and I believe are the ones most of the miata kits are based on.

Jalopnik used SE-R calipers and Mini rotors for $350 total:

No way that fits under any 15" wheel. Fail of epic proportions.

They were using a factory 16" wheel.

Bolting random calipers on is not the correct way to build a Performance Braking system. Building a complete system is about finding an overall balance. bolt 14" carbon carbon rotors to the front of your car, and leave the rear stock you'll lock the front tires and your performance will be dramatically decreased.(even though you just spent 10g's on calipers and rotors)


Never believe anything you read on jalopnik, any 3rd grade english student does more fact checking then they do.

I tried the 11.5" mini rotors when I messed with this in the beginning check post #100 for pictures of the 11.5" rotor and Dynalite calipers under the NB 15" wheels. It was tight and needed a wheel spacer. I also tried the 11.5" rotors with factory calipers and could not make it fit. There is no way you could fit those larger SE-R calipers under a 15" wheel.

I doubt the SE-R pads are any cheaper than the dynalite pads which are as cheap as it gets and is one of the primary reasons I chose this setup. The willwood calipers are dirt cheap too. The fact that almost all of the performance 11" and 11.75" kits use these calipers helps too. They are sized to work with the miata hydraulics.

Welding and drilling/tapping brake caliper mounting points would not be my first choice for something as important as brakes!

Finally got some track time in with these beasties!

Carbotech XP8 all around, no brake ducts, fresh ATE SuperBlue, stainless lines, non sport master and non sport 1.8 rear brake setup. Tires were 2 year old 205 NT-01 on 15x8 6UL and everything bolted to my overweight NB1. Bedded the pads into fresh Centric rotors on Hwy 68 on the way to MRLS I ran in Group C because I was out of town on business and forgot to register for track time until late. Plus I'm slow.

Breaks are awesome. NT-01 and Carbotechs are a hoot to drive. I was able to outcorner and outbreak most everything in my group except for the much lighter NAs that were in a higher state of prep. I had more breaking confidence than most of the other folks on the track, and this made for some interesting entry/exits on the corners. Balance is great and it gave me enough confidence to try a little trail breaking in the corners to keep a little more weight on the nose.

All in all I really enjoy these breaks and the XP8s. Gotta get some more trackdays in so I can start to relearn the car and get faster!

I know this thread is 3 years old. I am running corrado rotors and want to convert to Mini rotors as I can see they seem to be better vented. What's the year or part fitment for Mini rotors. I have dynalite calipers - should I just add more cooling to them or use Mini rotors ?

lbatalha

As the thread states, rotors for non-turbo minis that are 11". Quite easy to find the right ones. (just search for the base model 07-13 or so)

If you don't have 2.5" brake ducts, do that, its always a good idea.

stevos555

Brake ducts and Mini rotors or for corrado.

lbatalha

Brake ducts always worth it for any setup. Mini rotors wont really save you if you are on the thermal limits of the corrados IMO, at best its a short term bandaid.

The 11" rotors come off of the earlier non-turbo/supercharged Mini's. I don't remember the exact years. You will need different caliper brackets to fit the same Dynalite calipers on the Mini rotors since the rotor offset is different between the two.

If you have aftermarket wheels that can fit a little more brake rotor I would recommend the 11.5" Mini rotor from the turbo/supercharged Minis. They will not fit under factory Miata 15" wheels, but fit without spacers or only need thin spacers to fit under most aftermarket 15" wheels.

No matter which option you choose, add brake ducting. Even though you might not be exceeding the pad temperature limits without ducting, it will always add pad life and more consistent brake response.

The Corrado rotors benefit very little from ducting because they pull air from the wheel side of the rotor so any air directed at the rotor hub does not get pulled through the disk. This is the main reason why Corrado rotors are not the best solution for track use. Go look at some of the old threads that show how the Corrado rotors fail. The factory Miata , Mini and all performance rotors pull air from the hub side of the rotor so that cooler brake duct air directed at the hub get pulled through the disk to optimize cooling.

I've got 2 (and am looking at a third) car with the old FM Dynalite/Corrado rotor setups and would love to move to something better/more current without spending a life savings on it. I'm not a hard core track junkie so converting to the Mini rotors smells like a winner for my needs. Is anyone making the brackets or is this a brew-your-own scenario? Any template exist for what you guys have done if it is DIY? I hate solving a problem someone else already solved.

I make these brackets. PM me if you are interested.

Did you happen to get a OD measurement of the stock calipers on the 11.75" turbo rotor? I'm running 9" 6UL's and Dial In's, which are pretty big. I'd jump to the willwoods but I've got a pretty good stash of pads for the stock calipers I'd like to use up first. I'm only getting 3 track days out of a set right now so I'm on the ragged edge even with ducting on the stock rotors.

Here is a quick mockup I did tonight of the 11.5" rotor with caliper under Dial-In 15x7" (gray) and 15x9" (black) wheels. The 15x7" is a little tight with only 1/8" between outer edge of caliper and lip on the wheel. With 1/8" or 1/4" wheel spacer you would be golden and have as much room as the 15x9" wheels. The 15x9" wheel had over 3/8" room, more than enough to make it work.

Sorry, the pictures suck, but should give you an idea.

I'm not seeing the pics, but thank you for confirming that it works. Rotors on the way and you have PM.
