XYZ Racing Hollow Rear Brake Kit — Subaru LEGACY φ 265/ φ 171 (1989-1994)

The first-generation Subaru Legacy carried more braking duty rearward than most cars of its era. Symmetrical all-wheel drive puts genuine load through the back axle, and the original φ 265 setup was specified for a 1989 saloon, not for three decades of fast-road and trackday use. This XYZ Racing Hollow Rear Brake Kit rebuilds that corner of the car around a 265mm two-piece floating rotor and a fresh caliper, restoring the bite the BC saloon and BF estate lost long ago.

It is a rear-axle kit, a matched pair of left and right corners, so it works alongside a front upgrade rather than against it, sharpening balance under trail-braking instead of dumping all the work onto the nose. For an EJ-powered Legacy that still gets driven hard, this is the half of the brake equation owners usually neglect.

What this rear brake kit does for your 1989-1994 Subaru Legacy

The 265mm rotor adds swept area and thermal mass at the rear, so repeated heavy stops fade later and the pedal stays firm deeper into a session. Because the kit retains the φ 171 drum-in-hat, your handbrake works exactly as Subaru intended: no bodged parking-brake delete, which matters on a thirty-year-old car that still has to pass an MOT and hold itself on a hill. Three pad compounds let you match the car to its job: a Street pad for a recommissioned road Legacy, a Sport compound for fast-road work and the odd track day, and a Racing compound for circuit days. The result is a rear axle that supports the front under braking instead of locking early, giving a more progressive, more predictable stop on a chassis whose AWD layout rewards a balanced setup.

About the Hollow rear brake kit

XYZ Racing builds this as a complete rear corner: a 265mm two-piece floating disc, a matched caliper, mounting hardware and your choice of pad. The φ 265 / φ 171 dimensions are the headline, a 265mm friction face wrapped around a 171mm integrated parking-brake drum, so the package bolts to the first-gen Legacy without sacrificing OEM functions. The floating disc lets the friction ring expand against an alloy bell to keep the rotor flat under heat, and the caliper body is a hollow-cast forging as standard for a firm pedal. Calipers are painted Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 plus premium polished-forged and candy finishes, so the look behind the wheel is yours to set. Disc faces come drilled or slotted at the same price, and the centre bell upgrades to a five-colour anodized two-tone or titanium at checkout; a Hollow Racing caliper rated to 1000C with a two-year warranty is available for dedicated track use. Pad choice spans Street, Sport and Racing compounds, covering everything from a tidy daily to a car that sees the occasional lapping day. It is engineered as an upgrade over tired, hard-to-source factory rear hardware rather than a like-for-like replacement, which is exactly what these cars need now that good original parts have dried up.

Fitment for the Subaru Legacy (1989-1994)

This kit is cut for the first-generation Subaru Legacy built between 1989 and 1994, the BC saloon and BF estate range. It is a rear-position fitment specified around the φ 265 rotor and φ 171 parking-brake drum dimensions listed above. Confirm your car’s existing rear disc and drum sizes against those figures before ordering, as Legacy rear setups varied across the range.
