+1. I couldn't even get away with HPS on the street.

I was sarcastically ******* around when I posted that. That's why I included the "". It was a reference to a thread about the sport brakes, hustler pointed out that he had issues with them, and then another guy came in and sung their praises- but that other guy never tracks any of his cars (although he frequently brags about how many miles he racks up on the highway), and really, if you're not tracking, there's no reason to upgrade the brakes in the first place, so...

The problem is the manufacturers rape us for the rings and hats to fit 15" wheels. Any 6x6.25 ring is double or triple the cost of the same thing in 8x7. You can buy 11.75" rings for around $30. Same rings in 11" are over $80. Bastards.

Ducting is key. I still crack Corrado rotors, but the ducting means I can run ATE and not worry about boiling it off.

I'm trying to run blues with ducting on my sport brakes next weekend. If pads are only going to last 2-3 sessions, I'm buying the cheap crap.

Pics of said ducting? Inlet where? Diameter tube? Aiming how and where? I've got some 3" coming my way.

Does anyone have pics of installed ducts? I am interested in how/where you would route the ducting.
I was also wondering if you have to be concerned with channeling water directly to the brakes if the ducts are used on the street? If so I am sure you can easily block the ducts or remove them and only use them on track.

How do you fry pads on the street? I can see riding your brakes through the mountains instead of downshifting, but thats the drivers fault and not the brakes.

How often do you do 100+mph-30mph deccelleations on the street? I have drive veryconservatively when it comes to brakes. I have always felt if you drive right with a manual transmission, brakes are mostly needed in emergencies and when coming to complete stops. Once again, on track its a completely different story. It's not like our cars weigh several tonnes and take massive brake forces to slow down.

Hell even doing a top speed run to full stop can't be that bad, unless you do it repeatedly, and why would you do that unless you confused the street for your Need for Speed game. LOL.

The fast guys in spec Miata don’t use much brake They just lift and turn for allot of the corners or just a light tap. I realized this after trying to drive a stock powered car fast at the track after being use to around 3 times as much power. It was dificult for me to re learn to enter corners without using any brakes or to perform downshifts into corners without using too much brake and coming off the corner dead slow with no power to accelerate.

When I first started doing HPDE’s I was really hard on brakes. Cracked corrado rotors and even rear rotors, tried pad compounds that fade or wouldn’t even last a full event etc. After years of practice and lowering lap times I am much easier on my brakes now I think. I fixed my brakes however with my own brake kit. 11.75” Wilwood DynaPro Mini cooper kit in the front (Yes it is pretty much a bolt on for a Miata more brake than the FM goodwin kit and cheaper). 11.44” two piece in the rear Cobalt friction XR2 pads for the track. Never worry about not having brakes and they last many track days even with 350 hp. This is the most brake I think I have seen anybody stuff into a 15” wheel yet.

I run Hawk Blues/HP+ on my MSM with good luck. Might try HT-10 next in the fronts. I heard the Blues will ruin your wheel's finish if it gets wet. Carbotech XP10/8 is another good combo.

I'm running blues for one more "cycle" becuase the carbotech's warped pretty badly. Maybe they needed ducting, lol. I'm serious trying to not run Blues with my gorgeous, bronze 6ULs. If I must, they'll be sprayed with Pam before I bolt them up.

Hmmmm....never thought of using Pam before. Does Pam contain Teflon?

luckily for me, most local tracks (willow springs big track + streets of willow, buttonwillow) dont require much braking at all. i get away with less aggressive pads that i can still use on street with minimum amount of noise, dusting, and heating up.

Pam can't contain teflon, since it's used for cooking.

bob,
Aren't you the guy who drives the car to and from the track? I hope to join your reign of "driving to the track, dominating, and driving home" terror. I also see a turbo 323 back there.

edit: You're car, work, and track rep are quite respectable.

When I was at his house there were 4 of them on his property lol.

I think he should sell me one I tried to buy one off a guy locally that delivers pizza in it, he said he bought it for 600 bucks and is never selling it. Where the **** do you find these things, let alone for 600 bucks?

A couple track days ago a guy in a gtx broke a diff on the backside. He shut down our day for 1/2 an hour since he wouldn't let they tow him off. Didn't want to be towed and screw up the 4wd system even worse. They had to trailer him off.
