XYZ Racing Hollow Rear Brake Kit — Mazda RX-7 FD3S (1992-2002)

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.
