7 kits sold, 3 available at our $600 group buy price.

Finally got some test time on our BBK so the group buy can begin.

This kit will retrofit a Wilwood 4-piston caliper and an 11" VW Corrado front rotor to your Miata.





This kit will include the following:

-Wilwood Dynalite forged 4-piston caliper
-Trackspeed Engineering caliper brackets
-stainless steel brake lines
-centering rings for Corrado rotors
-Grade 8 hardware

Where are the pads and rotors?
The kit will NOT include pads and rotors - we think a lot of you already have the rotors, and there's a vast variety of pad compounds out there. We'll be recommending standard cheap rotors and Carbotech pads, and we can source this combo and ship it with the kit for an additional cost.

Can I buy just the brackets?
A lot of folks asked for the brackets alone as well, and we'll be selling those separately for those of you who have calipers, or if you want to source everything else yourself. Bare brackets will sell for $170.

What are the benefits beyond a standard Corrado rotor upgrade?
The biggest benefit is pad life. The stock caliper unevenly distributes the force of the single piston across the pad, which results in tapered wear patterns and severely compromised pad life. I've also experienced rotor cracking resulting from this uneven loading. The Wilwood calipers are 4-piston and non-floating, which means the loads are far more even. In my testing, the pads wear straight, and I expect to get at least double the life out of my track pads using this caliper vs. a stock caliper with Corrado rotors.

What about brake bias?
We are HIGHLY recommending you couple this kit with a Flyin' Miata brake bias valve. The stock valve is biased heavily towards the front and adding big front rotors and calipers won't help that at all. With the bias valve in place, and using Carbotech XP12 pads front and rear, the bias in my car is to my liking.

Do I need to have 1.8 caliper brackets to use this kit?
No. This kit will retrofit to any 1990-1997 Miata - simply remove the stock caliper, caliper bracket, and rotor, and bolt up the new stuff.

Why do I need new lines?
The Wilwoods don't use a banjo fitting, so stock brake lines and aftermarket lines designed for stock calipers won't work.

What about wheel clearance?
The kit fits on any car with 6ULs. We will try to get a variety of wheels onto my car for fitment testing in the next few weeks.

What's this going to cost me?
Retail pricing on this item will be $650. For this group buy, the first 5 orders will get $100 off, and the second 5 will get $50 off. All buyers will pay S/H, CA residents will pay sales tax. (discounts for full kits only, brackets are full price)

Send order inquiries to sales@trackspeedengineering.com, and include the following:
-First and last name
-Paypal address
-Shipping address (for S/H/Tax calculation)

 

I cannot wait to get mine installed. Once installed, I'll let everyone know about the fit and finish

 

Got mine installed in about 45 minutes from lifting the car to setting it down. Finish is great and unbelievably lightweight. I had the M-Tuned kit on there before and this combo probably weighs 5-6lbs less than that one. So light estimate of 15lbs of unsprung weight taken off of my car.

 

I'm glad to hear the install went well.

They are available now through our online store - you can order them there and get the $600 price.

If one were to order the brackets only do they also get a set of centering rings for the Corrado rotor? I'm not sure if rotor centering rings are as useless as wheel centering rings.

Rotor centering rings are much more important than wheel centering rings. The wheels are lugcentric - the rotors are not.

Rings and brackets are available as a package for $200.

 

Fit and finish is PERFECT with this kit. Wilwoods are sweet BTW.

Where can I get speed bleeders for these? The bleed screws are TINY!

 

I just got my centering rings and hangers in the mail. They look very good and the folks at TrackSpeed are more than willing to help with advice and such.

I'll have more to say when the rest of the stuff arrives from Summit, RockAuto and 949Racing and goes on the car but so far I'm impressed.

Thanks TrackSpeed for offering a route to a "real" big brake kit that does not cost over $1000 to buy and rely on outrageously expensive wear parts to maintain. This has been needed for a while now.

Sav- Are you running stock front wheel bearing or the ART blueprinted version?

 

Here are a few sources for speed bleeders that should work. We have not used them though.

Currently stock front wheel bearings, but when they get replaced ART hubs will go in their place.
