XYZ Racing Hollow Rear Brake Kit — Mazda MX-5 (1990-1998)

The first-generation NA and early NB MX-5 carry barely a tonne between them, and almost all of that mass sits low and central. That is exactly why the rear axle is so easy to upset: lift mid-corner and the tail rotates willingly, which is half the joy of the car and half the reason a poorly balanced brake setup ruins it. This XYZ Racing Hollow Rear Brake Kit for the 1990-1998 Mazda MX-5 is about controlling that rear end on the brakes, not just adding hardware for the sake of it.

The factory rear discs on these cars are tiny, sized for a road car that nobody expected to see a circuit. Swap to this rear brake kit, a pair of left and right rear calipers with matched discs, and you get a larger, hollow-vented rotor that sheds heat and rotating mass, with a caliper and pad package you can spec to match how hard you actually drive.

What this brake kit does for your 1990-1998 Mazda MX-5

On a car this light, the gain you feel first is consistency. The hollow rotor design reduces unsprung and rotating weight at the rear, so the axle settles faster over kerbs and the brakes recover heat between corners instead of cooking on a hot lap. Repeated stops from speed stay predictable, which matters far more on an MX-5 than outright stopping distance. Choose the Racing pad compound and the rear bites hard enough to help rotate the car into a turn; the Sport compound suits fast-road and the occasional track day; the Street compound keeps quiet, low-dust manners for daily use. Either way, pedal feel stays firm because the rear is no longer the first thing to fade.

About the Hollow Rear Brake Kit

The kit pairs a hollow-construction rear rotor with an XYZ Racing caliper, sold as a complete bolt-on package for the rear axle. The two-piece floating disc is the headline: removing material from the disc body cuts rotating mass and improves airflow without sacrificing the thermal capacity you need under sustained braking. Discs are offered drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. Pad compound is a buyer choice across Street, Sport and Racing options, so the same hardware can be set up for a road-biased NA or a dedicated track NB. 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. Caliper finishes are available in the included painted colours (Red, Yellow, Gold, Black and Anodized Black), a Custom Color matched to any Pantone, or the premium polished and candy ranges, so the look behind a set of period wheels is yours to decide. It is engineered as a focused rear upgrade rather than a full corner rebuild, which keeps the install straightforward on a chassis this simple.
