Caliper render for this kit:

The FD3S RX-7’s rearward weight transfer under hard braking is exactly where its factory rear discs run short of thermal headroom on a circuit. This XYZ Racing Hollow Rear Brake Kit for the Mazda RX-7 FD3S (1992-2002) adds disc area and clamping at the axle that does the delicate work on a tail-happy, rotary-powered coupe.
Built around hollow-design discs to shed rotating mass, the kit gives the rear axle the heat capacity to take repeated stops without cooking the pad. On a sub-1300kg car that rotates on the throttle, getting the rear brakes to behave predictably is half the battle, and this is a rear big brake kit, a pair of left and right rear calipers with matched discs, aimed squarely at that problem.
What this big brake kit does for your 1992-2002 Mazda RX-7 FD3S
After fitting, the first thing you notice is a firmer, more progressive pedal as the rear axle starts pulling its weight into the braking zone. The hollow disc construction trims rotating mass at each rear corner, which sharpens turn-in and lets the dampers work with less inertia fighting them. Pad compound is your tuning lever: the Street option stays quiet and low-dust for road use, the Sport compound adds bite and a wider heat range for spirited B-road driving and the odd track day, and the Racing compound holds friction through the heat of back-to-back track sessions. Match the rear pad to the front and the FD’s braking balance becomes something you can lean on rather than second-guess.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit is XYZ Racing’s rear-axle upgrade built around lightweight two-piece floating discs of hollow construction and a hollow-body caliper that clamps more evenly than the FD’s standard sliding arrangement. Cutting unsprung and rotating weight at the rear is the point: less mass spinning at each hub means quicker response and less energy stored as heat. Discs are offered drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. The kit is offered with three pad compounds, Street, Sport and Racing, so the same hardware suits a daily-driven RX-7 or a dedicated track car. The hollow-body caliper is standard, with an optional Hollow Racing upgrade rated to 1000C, no dust cover and a two-year warranty for serious circuit use. Calipers come in the included painted colours (Red, Yellow, Gold, Black and Anodized Black), a Custom Color, or the premium polished and candy ranges, so the view behind the wheel matches the rest of the build. It is a rear-specific kit, designed to pair with a matching front setup for balanced bite across the axle.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).


Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
