XYZ Racing Hollow Rear Brake Kit — Mazda 3 (BP) (2019-2026)

For hard road and trackday use in the BP-generation Mazda 3, the XYZ Racing Hollow Rear Brake Kit addresses the one corner Mazda left modest from the factory. The fourth-generation 3 carries its braking load heavily at the front axle, and the standard rear discs were sized for a refined daily hatch rather than repeated heavy stops. This kit gives the rear axle something to contribute.

The two-piece floating disc strips rotating and unsprung mass from each rear corner, which the torsion-beam rear axle of the BP feels directly in how quickly it settles. With Street, Sport and Racing pad compounds and a full range of caliper finishes, you spec the rear end to match how you actually drive the car.

What this brake kit does for your 2019-2026 Mazda 3 (BP)

After fitting, the first thing you notice on the 2019-2026 Mazda 3 is a firmer, more progressive pedal that holds its travel deeper into a braking zone. Because the rear axle now does a fairer share of the work, forward weight transfer is better managed and the nose dives less under heavy braking, worth having on a front-biased chassis that already loads its front tyres hard. The two-piece floating discs shed heat and rotating mass, so a sustained run of stops on a fast B-road or a circuit session no longer pushes the rears toward fade. Run the Racing compound for trackwork, the Sport compound for fast road and the occasional track day, or the Street compound for quiet, low-dust manners and strong cold bite on the road. Painted caliper colours in Red, Yellow, Gold, Black or Anodized Black, with premium and Custom Color routes besides, let the rear end look the part behind open-spoke wheels.

About the Hollow rear brake kit

The Hollow rear brake kit takes its name from the hollow-bodied caliper, fitted as standard, paired with a two-piece floating disc whose vented structure cuts rotating mass without surrendering thermal capacity. It is built as a direct rear-axle upgrade for the BP Mazda 3 rather than a universal part, so the caliper, bracket and disc are sized to the car. Serious trackwork is covered by the optional Hollow Racing caliper, which drops the dust cover, is rated to 1000C and carries a two-year warranty. Three pad compounds are offered, Street for quiet road manners and strong cold bite, Sport for more heat range on fast road and occasional track, and Racing for sustained high-temperature trackwork, so the same hardware suits a daily driver or a dedicated track tool. 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 to your spec. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. The aim is to raise rear braking capacity and restore front-to-rear balance on a platform that runs a conservative factory rear setup. It is supplied as a pair.

Fitment for the Mazda 3 (BP) (2019-2026)

This kit is cut specifically for the BP-chassis Mazda 3, covering the 2019 to 2026 model years across the fourth-generation hatch and saloon. It mounts to the rear axle as a pair and is matched to that chassis, so check that your build year falls inside the 2019-2026 span before ordering.
