Fitment: NA & NB Miata · 1990–2005 · Front kit position
With extensive knowledge and background in motorsport products and services, we understand customers’ demand for street, track prepped and race vehicles.
V8 Roadsters doesn’t sell five separate front kits per generation. The public Miata brake catalog runs to roughly 25 products in total — front kits, rear upgrades, four-wheel packages, rotors, hats and hardware — and most of the front kits are a single product page with a set of real configuration choices: which Wilwood caliper, which rotor diameter, fixed or floating mounting, and which rotor face.
This guide organizes those configurations into five stages so you can start from how you drive rather than from a parts list. Each stage below names the actual product, the exact configuration, and links straight to the page where you’d buy it.

Parking Brake Limitation
The optional Powerlite parking brake is intended for parking on level surfaces. V8 Roadsters notes it does not provide the same holding force as the factory parking brake and should not be relied upon to hold the vehicle on steep inclines.
If you regularly park on a grade, factor this in before choosing a rear caliper kit with the parking-brake retrofit — and always leave the car in gear as well.

What Comes With Your Kit
What Actually Changes Between Stages
Fixed vs Floating Rotors
A fixed rotor bolts the iron face solidly to the hat. It costs less, and for street and autocross use it is entirely adequate.
A floating rotor lets the face expand against the hat as it heats. Under sustained track heat that reduces the stress that can cone or crack a face, and it keeps the disc running truer. It costs more, and it adds hardware that is itself a wear item — V8R sells floating-hat hardware separately for exactly that reason.
Note that on the NA/NB Big Brake Kit, choosing floating also requires the V8R Directional rotor (+$150). That mandatory upgrade is baked into the floating prices quoted in the matrix above.
Practical read: street car, take fixed. Repeat HPDE or wheel-to-wheel, floating earns its price.
Lug vs Radial Mount Calipers
Lug mount calipers bolt through ears on the caliper body. Radial mount calipers bolt through the caliper along the axis of the rotor, which V8R describes as reducing lateral caliper flex and pad taper.
In the Wilwood Dynapro family, going radial also brings a bigger pad: plate 7816 (16 mm) instead of 7812 (12 mm). That extra pad volume is the concrete, measurable benefit. On the NC and ND lug-mount kits you can also step up caliper piston count.
Radial is not automatically necessary for a street car. If you never generate the heat that causes taper, you are paying for stiffness you won’t use.
Rotor Diameter vs Thickness
Diameter increases the leverage the caliper has on the wheel and grows the swept area. Going from 11″ to 11.750″ is the single biggest step in the NA/NB ladder.
Thickness is thermal mass — how much heat the rotor can absorb before it starts giving it back to the pads and fluid. The 11.750″ and 12.19″ big-brake rotors both run .810″. The 12.19″ × 1.25″ rotor appears only in the NC/ND XRZ4R Competition kit.
Both add rotating mass. Bigger is not automatically better for a car that never sees a track session.
Pad Volume
Pad thickness climbs across the ladder: 12 mm (Dynapro Lug) → 16 mm (Dynapro Radial) → 20 mm (Superlite and XRZ4R).
More pad means more material to absorb heat, a slower wear rate, and more sessions between pad changes. On a track weekend that is often the difference between one set of pads and two.
What it does not reliably mean is a shorter stop on a cold first application. Pad volume is about sustaining braking performance, not raw peak grip.
Frequently Asked Questions
Are Stage 1–5 official V8 Roadsters product levels?
No. V8 Roadsters does not use “Stage” or “Level” naming on its brake products. The stages on this page are a guide framework built by V8R to organize the real products and configurations by intended use.
Every stage on this page names the actual product and the exact configuration behind it, and links to the real product page.
Does the Powerlite parking brake hold the car on a hill?
No — V8 Roadsters states the optional Powerlite parking brake is intended for level-surface parking only and does not match the holding force of the factory parking brake. Don’t rely on it on a grade.
Will these brake kits fit my wheels?
It depends on the kit and your wheel’s diameter and offset. For the NA/NB kits, V8R publishes general guidance (e.g., clearing most current aftermarket 15″ wheels) with no numeric minimum. For the NC, the spec sheet indicates a minimum 16″ wheel, with clearance referenced for many 16″ wheels (including stock) and standard-offset 17″ wheels. For the ND, the spec sheet indicates a minimum 15″ wheel for 11.75″ rotors and 16″ for 12.19″ on the Big Brake Kit stages.
None of these are universal guarantees — check the wheel template on the product page before ordering.
What is the difference between fixed and floating rotors?
See “What Actually Changes Between Stages” above — fixed is simpler and cheaper; floating handles sustained track heat better but costs more and adds a wear item.
What is the difference between lug-mount and radial-mount calipers?
See “What Actually Changes Between Stages” above — radial mounting reduces caliper flex and pad taper and typically pairs with a thicker pad.
Do I need a rear brake upgrade with a front big brake kit?
Not necessarily. A rear upgrade is optional — consider it when the front kit meaningfully out-performs the stock rear and brake balance needs restoring, or when you want the reduction in unsprung weight a lighter rear caliper provides.
If you want a matched front-and-rear package from a single product page, both NA/NB and ND offer a complete four-wheel kit; the NC front and rear kits are bought separately.
Are brake pads included?
Not confirmed across every NA/NB kit in this lineup. The NC and ND kits are sold without brake pads, so you can match compound to your use — confirm on the product page, and budget for pads separately if they aren’t listed.
Why can the configured price be higher than the displayed product range?
On the configurable Big Brake Kits, rotor-diameter and rotor-face options are handled as product add-ons, so the price range advertised at the top of a product page does not always include them. For the NC, the entry configuration also carries a mandatory +$10 option cost that the WooCommerce headline price excludes.
A fully configured cart total can exceed the advertised range — always confirm your total in the cart with every option selected.
Can I combine the NC Rear Powerlite kit with the NC Two-Piece Rear Rotor & Hat Kit?
Yes. Select the larger 11.88″ rotor option.
Product specifications and pricing reviewed July 10, 2026. NC and ND specifications reflect current V8 Roadsters spec sheets. Configurations, availability and pricing may change as V8 Roadsters updates its product options. Verify final fitment and selected options on the linked product page before ordering.
