Wilwood Releasing Miata BBK, Only $635 for Fronts
 

Someone on m.net was apparently a tester:

He upgraded a few parts from the standard kit:

Attachment 194300

And some other information, posted on CR.net of all places:

Can't see the pic - does this use a two-piece rotor?

Yup.

Hrmmmmm.... I might have to look more into this.

Wirelessly posted

How much are replacement rotors, do they fit with 6ul offsets, are the rotors readily available at all times?

Not big enough to justify replacing my big sport brakes.

FWIW

The off the shelf wilwood kit 140-8740 made for a Mini Cooper is pretty near a direct bolt on for a Miata. A couple of washers and a hat centering ring are all that is needed.

Dyna-Pro > Dyna-Lite
11.75” > 11”
.60 thick pads > .49 thick pads
Directional Vane > Straight Vane

I have been running this kit for a number of years. I Pioneered the installation.

Id like to figure out how a setup for the rear using one of their parking brake combo calipers. Seems like the parking brake cable is oriented wrong however and they are only made for vented rotors which in my testing has shown is just unnecasary weight for the rear of even the highes powerd miata track cars.

Currently I have a custom 11.44” two peace rear rotors with stock calipers.

Bob

bbundy, it's also $1075 vs. $700 for this supposed new BBK. I'd take the dyna-lites, 11" rotors, .49" thick pads, and straight vanes to say $375. Then again I may not be finding the best price for the kit, this was directly off Wilwood's site.

bah. non abs only for now

I built mine when the only other options were Goodwin and FM who I felt wanted twice what it should cost so I got a much better kit which still cost slightly less than theirs. I was regularly destroying both pads and rotors on the corrado based wilwood setups. my new kit works better and has at least 4X the pad and rotor life.

Finally wilwood stepped up and put the kit together for what it should cost. I suspect the other players will have to lower prices or sales will die off.

I have found www.Summitracing.com usually has the best wilwood prices usually less that wilwood lists.

Bob

What would make this non-ABS compatible?

For the life of me I can’t figure out how it would not work with ABS. The tone ring is on the hub I can't see how anything would interfere with the abs.

Bob

Hopefully the prices and hype are true. Isn't the free market wonderful? ;)

Seems Good-Win is following the trend for $699 (including lines) front only, looks like different hats, caliper brackets, and pads:

So the wilwood and goodwin kits are pretty much the same price. The rotor hat on the wilwood kit looks better =P

I know what i'm buying this spring!

Id recommend 2001+ sport brakes for the rear to go with it.

Oh and a 1" master cylinder on a 2001 + booster does wonders for pedal feel.

Bob

Yes when it finally works right. I forget how long ago it was that I complained about the price. Goodwin and FM were charging nearly double what basically the same kit cost made for cars even with a smaller or much larger markets than a Miata.

Bob

Oh ya that too. I'm planning on doing more track days than autox next summer so I really want to get my brakes and cooling (oil and water) sorted out before then. I think this would be a good setup to grow into and if I outgrow it I'll sell it and go with a copy of your setup.

That's the advantage of being first on the market, such as with the 949 wheels. FM AFAIK is a reseller of the Goodwin kit so they weren't competing. I'm not saying 949 wheels are overpriced, as even when they first came out they were priced right vis a vis the not-quite-competition (15x7's).

The time it took for Wilwood to enter the market tells me that there's a lot of opportunity out there for small biz to compete (auto aftermarket, not specifically miata bbk's).

If you want to be horrified, look at the prices of E36 BMW BBK's. My car came with front BBK's which I didn't need, I downgraded to stock, and sold the ones from the car for $1700.

Hopefully the replacement rotors will get cheaper, they are about $80-100 each right now, if they went with the 11.75 they can be had for $30ea.

Suddenly the Miata market is exploding. The TSE RB replacement rotors are $90 each or you can run Napa shit on the street for $25 each.

FML... should have waited a whole 30 days to buy my kit. For the same price I could have had 2 pc rotors.

And having run the RB rotors, I'd recommend NAPA shit even if they were the same price.

I have a lot of respect for Emilio I think he entered the market with something nobody had and did it with an extremely fair price. I don't think anybody can undercut too much and have an equivalent product without loosing money doing it. The copies are much lower quality and heavier thus far.

Bob

Hey Bob, how in the hell did you mount radial mount calipers to the Miata hub?

The mounting brackets that come with the Mini-cooper kit fit the Miata as well. My wife was in shock when she saw her Mini up in the air next to my Miata when I was test fitting her brakes on the Miata. Both the rotor and the hat bolt on. In the radial direction there is 3/8" difference however but that is pretty easy to adjust with a radial mount caliper. The Mini kit was already designed to work with both 11.75 and 12.19" rotors. There are actually a few 15” wheels that would take a 12.19 rotor.

Bob

Ahhh I see now. It's the fact that the MINI diagram has the caliper on the front and was kinda hiding the way the radial mount bracket works. I get it now.

Which makes me now wonder- Is the caliper bracket different from the 11.75 kit ro the 12.1 kit or if both kits use the same caliper bracket and one just accepts the larger rotor.
Either way, I'm going a lightly different route that will all (hopefully) be Miata-specific...but pieced together. I just need to hear back from V8R to see if they'll sell their caliper mounts seperately and what offset the hub needs to be with their bracket.

That's the old V3 Goodwin kit. Same 160-5840 rotor that Wilwood is using.

Do you think the rotors will get any cheaper now that Wilwood is offering a kit themselves?

Not.

Damn this is awesome. Curious as to how they hold up on v8 applications.

I just got to looking at the pictures and the kit from wilwood has DynaPro calipers instead of Dyna Light. The Dyna Pro calipers are way stiffer and I think they might use the thicker pads like my Mini brakes do. Retail price for the Dyna Pro calipers by themselves I think is normally double that of the Dyna Lights.

I'd take the Dyna Pro Kit.

Bob

The Wilwood kits comes with the same DynaLight calipers that Goodwin sells. The original poster on M.net upgraded HIS set to the DynaPro calipers that are pictured.

how well do the rotors respond to brake ducts? i can't tell from the pictures if air can be forced through the rotor from the inboard side.

Retail price on the DP4 is about $17 more than the DL4.

DP6 is another animal entirely, running about twice the retail of the DL4

BTW, we're offering a souped up version of the kit as well.

Dammit...I want 11.75" rotors and DP6 calipers.
Can I get 11.75 replacement rotors for those hats and be OK with those caliper brackets? Hmmmm

No you would need new brakets or I would have done this already

What about the radial mont DP4's though.

Bob

Radials cost more.
To get the actually realize the potential benefit of a radial though, the spindle would have to be redesigned so the loads are vectored directly at the centerline of the hub. As it is, we would have to cut off the bosses, grind them flat and still end up with the thing cantilevered a bit, indirect load path. I looked at doing this for the OGK with a custom set of offset V8R hubs but decided there were other more cost effective things we could do on the car to improve brake feel. I hate one off stuff that no one else can get. If I do something for one of our cars, I want to be able to serial produce it. In the end, an 11" kit like this can provide a rock solid pedal in actual race conditions. BTDT.

-Bump to a 15/16, 1 or 1.125 M/C.
-Fab a M/C brace
-Use stiff hats. Too much lightening, we have discovered, can contribute to knock back
-Run lots of rear brake bias if you have an effective wing
-Blueprint your hubs
-If you have deleted your e-brake, manually adjust your rear brakes after every hour or so on track.


Anyway Bob, You already have your DIY Monster BBK and it works right?

Yep mine works good, when I developed it there was nothing comparable in my opinion. Im just glad that finally good stuff is coming out at reasonable prices.

Now if wilwood would come out with a rear kit for a miata using one of there E-brake calipers like they have done for a bunch of other cars.

Bob

I wish someone would make a caliper that was affordable and not stricken with 8-failure points on each bleeder.

wut?

^^ do a search for "charmin moment" :laugh: j/k

btw, is anybody here still on 1.8 brake hardware? i'm thinking i'm gonna ride the 1.8 pony far as shell go (w/ ducting out the ass).

Yeah, I was in serious need or Charmin but luckily the e-brake was there.

I think standard 1.8 brakes with cuting and Hawk blues will work...but I don't think the bearings will last long. I'm going to start tracking my bearing temps because I saw an F1 car with temp-strips on the spindles. I bet that's why bearings only last me a few events at a time.

thats a great idea since u already got the stickers. looks like there is good place to put it on the hub inboard of the rotor as long as the sticker sticks and it doesn't get nuked from heat radiated by the rotor.

along these same lines, after reading the 6speed thread, i'm getting a temp sensor added to the casing of a gearbox i have in for a syncro refresh. its cheap ($45) and i had a spare channel on the dash.
