XYZ Racing Hollow Rear Brake Kit — Toyota MR2 AW11 (1984-1989)

The AW11 MR2 carries an unusually rearward weight bias for a car of its size, and that changes how it stops: the rear axle is asked to do real braking work, not just trail along behind the fronts. Toyota’s original rear setup was specced for a light 1980s road car, not for repeated hard stops on a B-road or a circuit, and it is the first thing to fade once you start leaning on the chassis.

The XYZ Racing Hollow Rear Brake Kit for the Toyota MR2 AW11 (1984-1989) addresses that directly. The two-piece floating disc design trims rotating and unsprung mass at the back axle, and the larger swept area gives the rear brakes the thermal headroom they need to keep the car balanced under load. It is supplied as a left-and-right rear pair.

What this brake kit does for your 1984-1989 Toyota MR2 AW11

On a mid-engined, short-wheelbase car the rear brakes are part of how the chassis rotates, so a stronger, more consistent rear end makes the AW11 more predictable on the way into a corner. You get firmer, more repeatable pedal feel as heat builds, less of the soft, vague bite the standard rear brakes develop when worked hard, and a rear axle that holds up through a full session rather than going long on the pedal. The lighter two-piece discs cut mass right where this car is most sensitive to it, sharpening turn-in and helping the suspension follow the surface. Pad compound is your call: Street for quiet road use, Sport for a fast-road car that sees the occasional track day, and Racing when the AW11 is being run in anger.

About the Hollow rear brake kit

This is a rear big brake kit built around a hollow-body caliper fitted as standard, cast with internal voids to cut weight without losing rigidity, clamping lightweight two-piece floating discs sized for the AW11 platform rather than adapted from a generic fitment. The two-piece construction lowers rotating and unsprung mass without giving up disc face, which is what lets the kit shed heat while keeping the back of the car light. Three pad compounds are offered, Street, Sport and Racing, so the same hardware suits a preserved road car or a weekend track machine. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre-bell upgrades. Painted calipers come finished in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone and premium polished-forged and candy finishes, so the kit can sit discreetly behind period wheels or stand out behind a modern set, and a Hollow Racing caliper rated to 1000C is offered for hard track use. It is a bolt-on upgrade for owners who want stronger, more consistent rear braking without re-engineering the car.

Fitment for the Toyota MR2 AW11 (1984-1989)

This kit is specced for the first-generation MR2, chassis AW11, across the full 1984 to 1989 production run. It fits the rear axle as a left-and-right pair and is sold as the rear half of the braking upgrade. Confirm your wheel clearance before ordering, as the AW11’s small-diameter factory wheels leave limited room at the back.
