XYZ Racing Hollow Rear Brake Kit — Audi S2 COUPE (1990-1996)

The Audi S2 Coupe carries its iron-block 2.2 20v turbo five ahead of the front axle, and that weight bias shows up most clearly under braking, once the quattro driveline has shuffled torque around and the rear axle is asked to do more than the factory setup ever planned for. The XYZ Racing Hollow Rear Brake Kit targets the back end specifically: more thermal headroom and a firmer, more progressive pedal for a car that is now a thirty-year-old classic still being driven hard.

This is a rear-axle upgrade, not a front-only headline fix. On a permanent four-wheel-drive coupe, balanced braking matters, and upgrading the front alone can leave the rear lagging and the car squirming on turn-in. Specify it to suit how you drive, from fast-road duty to occasional circuit work.

What this brake kit does for your 1990-1996 Audi S2 Coupe

Fit the rear kit and the first thing you notice is a pedal that stays consistent as the discs heat, rather than going long after a couple of hard stops down from three figures. The two-piece floating disc trims rotating mass at each rear corner, which helps the dampers and the quattro driveline react more cleanly mid-corner. Pad compound is your call, with Street for quiet, low-dust road manners, Sport for harder fast-road use and light track work, and Racing for sustained track sessions, so bite and temperature window match how you actually use the car. Braided lines hold a firm pedal as it warms. On a heavy five-cylinder coupe, getting the rear axle to carry its share of the braking load settles the chassis on entry and makes trail-braking far more predictable.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is a rear-axle package built around a two-piece floating disc with hollow internal vanes that sheds rotating weight without giving up swept area, paired with a forged caliper that is hollow-bodied as standard and finished in the colour of your choosing. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone shade available to match the car. Three pad compounds are offered, Street, Sport and Racing, each with its own friction level and operating-temperature band. The lighter disc comes up to temperature quickly on cold UK mornings yet has the venting to resist fade once you start leaning on it. Because the calipers, discs and pads are matched as a single kit, clamping force and pad area are sized to work together rather than cobbled from separate parts bins. Braided lines are included, discs come drilled or slotted at the same price, and the centre bell can be upgraded to two-tone anodized in five colours or titanium. It is engineered to add thermal capacity and pedal consistency to the rear of a quattro coupe whose original brakes were specified for 1990s expectations, not for repeated hard use three decades on.

Fitment for the Audi S2 Coupe (1990-1996)

This kit is cut for the Audi S2 Coupe across the full 1990 to 1996 production run. It is a position-specific rear-axle kit (SKU XYZ-BRK-BKR-AU-06-A-REAR), a pair of rear calipers and discs supplied for the rear only. Confirm your exact build year before ordering, since trim and running changes across the S2’s life can affect rear hardware.
