The Rx7 calipers are still a possibility, we would just need a rotor with more offset. However, its turning out that these aren't easy to find.

Screw the heavy ass RX7 calipers. Wilwoods are good, light, and cheap enough.

How much are the wilwood calipers at cost?

But the RX7 Calipers can be had for cheaper.

Chris

If you think those are heavy, try picking up some Toyota 4runner/pickup calipers. Those are a brick in comparison.

If you think those are heavy, try picking up some calipers from a Kenworth cab-over. Those are an anvil in comparison. :cool:

So what about talking bout when an upgrade is needed in a braking system? As in what power levels a system should be able to handle? And when its time to upgrade...

Just been hearing alot of people saying the 1.8system w/ good pads is "more than enough" and wondering what systems/combinations are capable of what?

haha fair enough

Depends on the use, if you are driving on the street the stock system can lock the wheels up and is good enough. If you track the car hard you will want something that will be able to handle the constant heat and stress.

Chad, I've seen them around $300/pr new. Personally, I'm OK with spending $300 on a pair of new, high tech, lightweight calipers vs $60 on 20+ years old heavy things.

Well half of the old bags over at m.net tell you the stock 1.6 brakes are more than enough, too. I learned that was a load of crap when I overheated my stock brakes slowing from 120 - 40 and nearly ate shit.

i wouldnt mind either,

but you still need to take into account the pads, the rotors, the brake lines, and the bracket for that matter.

i calculated it up, it comes out to about 700 dollars total out of the pocket.

keep in mind that those old foogies dont drive their car as hard as we do, nor does their miata go as fast as ours either. well, at least 70-90% of them dont at least. we cant account for spec miata drivers though :rolleyes:

So what, you're buying new pads, rotors, and lines no matter what. :bang:
unless we use the 10" oem rotors, which almost all of us already have. then we can save like $50 on the rotors + whatever the spacers end up being.

My 1.6 brakes with dot4 fluid, hps pads, and stainless lines worked great on the track last year. We'll see how they hold up to r compound tires. My friends itr civic with huge willwoods and r compounds was incredible on the track until he ate an axle. Most of the magazine tests don't show any improvement with big brakes because they aren't getting them super heated.

so with these upcoming uber-upgrades on the horizon, anyone want to sell me their 1.8 brackets? ;-)

Spec Miata's are a good example of what stock brakes can do with proper pads. Those guy's run hard, fast, consistent laps with stock rotors, r-comps, stock calipers and good track pads. Even at endurance events I don't think brakes are a big issue for them.

Granted we have more hp, more weight and generally less skill but big brakes certainly aren't a neccesity. Nice to have if you want em and have the cash but stainless lines, frequent bleeding with high quality fluid, maintaining rotors and calipers and using proper pads for your track days will cover 98% of the needs out there.

we have more power, more weight, less skill, and LESS HEAT IN THE BRAKES typically. we need shit that grabs good in stop and go traffic, not just when hot.

HAHA, timing. Just got a call from Brembo.....

:jerkit::jerkit::jerkit::jerkit::jerkit::noob::noo b::noob::noob::noob:

My new (replacement) 91 is all stock, and there is no comparison to the one I had with big brakes and stopping. Granted, it is only street driven, but braking from interstate speed is noticeably different on the new one. It took me a few days to get used to not having the better braking and I had to remember that I was not driving my old car.

KMag

are these calipers the only ones that would work? im sure there are other models that might fit as well?

EDIT: ah nevermind. i just noticed they are the correct sizes for the corrado rotors. if we used different rotors, im sure we can fit a different caliper, but that defeats the purpose of having bigger brakes if we go with something smaller.

Are we talking using the Wilwoods for all 4 corners?

If so, what about using the Wilwood/Coronado combo up front, and using the 1.8's in rear? Throw off the braking balance? Or good way to skim some money?

Brain,

Me thinks though dost misunderstood. I am not advocating track pads for the street. I am saying use track pads for the track. Use street pads on the street. For the vast majority of people I THINK big brakes aren't going to be an advantage. Big brakes are big for a larger swept area for more bite and more surface area to dissipate heat.

I thought this was a general discussion about big brakes in addition to a how to. I used the spec miata example to demonstrate that our stock rotors and calipers provide plenty of clamping power and great fade resistence even in extreme use. I'm not a believer in big brakes, particularly only doing the fronts. Brake balance is too important in a panic situation and often ignored by street tuners. Stopping in a straight line is one thing. Stopping and turning with a poorly balanced system is another.

I'm likely completely wrong on the issue! I know that. I'm not an expert and certainly don't pretend to be. I simply haven't seen real world testing proving the benefits of big brakes on our cars. Also I'm a cheap bastard that doesn't want to spend hard earned money unless it's a proven benefit.

Almost 6000 views, wow. Some people are really interested in a good DIY BBK.

The fixed calipers are also supposed to give you better brake feel as compared to our floating design.

Chris

I think 11" fronts and Sport/01+ rears would provide good balance. You could always get an adjustable bias valve to fine tune to yuor liking. Wiliwood sells them as well.
http://www.pitstopusa.com/SearchResu...ategoryID=4478

These calipers are used in many of the BBK kits and the pads offer greater surface area than the other wilwood caliper posted in this thread.
I've often heard fixed calipers are harder on wheel bearings.

ah HA! thats it! not to mention 25 dollars cheaper! thanks

No problem.

A lot of this stuff was discussed in the Miata.net thread I linked to earlier. They even calculated some of the braking forces with diffferent master cylinder and piston combos as Wilwood offers several piston diameters and many people move up to a larger MC.

Actually made an excel spread sheet so you can plug in numbers;
http://home.comcast.net/~silentbob343/Brake%20Calcs.zip

These results will vary slightly from the numbers found in the miata.net thread as I found some small errors in the calcs and fixed them.

Every single person that's driven my miata with my 1.8L brake upgrade comments on my brakes being far superior. Every time I drive a 1.6L miata, even with the same pad, I comment on how shitty the brakes are.

1.8 brakes are far superior. More clamping and more leverage.
:bang:

not to change the subject, but can someone discribe the brakes in the OP? Moti's brakes didn't look much different that the old FM kit. If they are a big, unique, wilwoods, they are likely the brakes off my car that was stolen about 2 years ago. Anyone have info on who the person who put the ad up was?

OK! I'm an ass. Wasn't thinking about you 1.6 folks. :noob:

Did you try asking the person(Moti)who purchased the brakes? He would have a better idea who the person is.

oh. didn't realise Moti was selling them. Moti got his brakes from the same guy I did, but Moti isn't dealing in stolen parts...

+1 i think there's a lot of old school miata.net wine and cheese wisdom playing in on the generally accepted "1.6 brakes are all you need". my swap to 1.8 was night and day in terms of overall clamping for and in modulation. the only thing i'm worried about is that the stiffer the suspension the more you can use your rear brakes i wouldn't want to go to overboard on the front without using more of the capacity of the rears

so, who wants to make me some caliper brackets for those wilwood calipers and 01+ sport rotors? id go with calipers off 01+ sport but im kind of skeptical about dumping $300+ on USED calipers. id rather pay for new ones.

That kit already exists,it's made by Chikara motorsports,they also sell just the caliper brackets.

www.chikaramotorsports.com

never mind guys, i just bought all 4 calipers and brackets off 01+ sport for $180 shipped! :-P

they list them at around $3 per bracket?
that's dirt cheap

^ I'm pretty sure it's typo.

Here is a thread to our Big Brake Kit using the Corrado rotors..

https://www.miataturbo.net/forum/t28696/#post335453

Just took a look. The brackets are $300! Come on M-tuned. We need your Corrado kit!!!

If you are open to suggestions - you could sell brackets using the stock calipers all the way around and another for using a popular/common upgraded caliper. Wilwood for example. Hate to see you cut into Chikara's market:giggle: but $300+ for brackets is a little extreme!

We have started the sign-up for this kit. Want to ensure everyone who wants a set on here gets a set before I open it up on Miata.net as they will go fast!

Hey why wouldn't the brackets bolot up to the 1.6L cars.

in like flynn. Who wants to buy my sport brakes?
