XYZ Racing Hollow Rear Brake Kit — Mazda 3 (2009-2013)

On a front-drive Mazda 3, the rear axle only ever carries a fraction of the braking load, which is precisely why the standard rear discs get overlooked, and why they are the first thing to cook once you start lapping. The XYZ Racing Hollow Rear Brake Kit for the 2009-2013 Mazda 3 attacks the back end specifically, adding thermal headroom exactly where the factory setup runs short of it.

This is a balance and consistency upgrade more than a raw stopping-power one. With the front brakes doing the heavy lifting on a nose-heavy hatch, a stronger, cooler-running rear keeps the car settled under trail-braking and stops the rear pads glazing after a handful of hard laps.

What this rear big brake kit does for your 2009-2013 Mazda 3

Fit it and the first change you feel is a firmer, more progressive pedal as rear temperatures stabilise instead of climbing. The two-piece floating disc trims rotating and unsprung mass at each rear corner, so the wheels respond more quickly to the brake and the dampers find it easier to keep the contact patch planted over kerbs and broken tarmac. Three pad compounds, Street, Sport and Racing, let you match the rear to how you actually use the car, from a daily commute on the Street pad, through the firmer Sport compound for fast road, to a Racing pad for repeat track sessions where the original would already be fading. On a front-driver, a rear that bites cleanly and holds its heat is what keeps the 3 rotating towards the apex rather than washing into understeer.

About the Hollow Rear Brake Kit

The kit is built around a two-piece floating disc, machined to shed rotating mass without surrendering the swept area needed to manage heat. It is a rear-axle kit, supplied as a pair, designed to bolt to the 2009-2013 Mazda 3 and work alongside your existing or upgraded front brakes rather than replace the whole system. The caliper is hollow-bodied as standard, with an optional Hollow Racing caliper for regular trackwork that drops the dust cover, is rated to 1000C and carries a two-year warranty. Calipers come painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Color in any Pantone for £150, so the look behind the rear wheels can be matched to the rest of the car. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. The compound choice is the part that matters most on track: Street, Sport and Racing pads let the same hardware serve a road-biased build or a regularly lapped car, simply by changing the friction material. Disc sizing, hat offset and caliper mounting are specified for the rear of the Mazda 3, not adapted from another platform.

Fitment for the Mazda 3 (2009-2013)

This kit is built for the rear axle of the Mazda 3 across the 2009 to 2013 model years and is supplied as a pair. Confirm your car sits inside that range before ordering, then choose your caliper colour and pad compound when you order. As a rear-specific kit, it pairs with your front brakes rather than replacing them.
