XYZ Racing Hollow Rear Brake Kit — Cadillac CTS (2008-2013)

The second-generation Cadillac CTS carries its mass like the big GT saloon it is, and on a car this long in the wheelbase the rear axle keeps soaking up load every time you lean on the pedal. Hard road use and the odd track session expose that back end first: the standard rear discs heat-soak, the pedal lengthens, and stability under repeat stops starts to wander. The XYZ Racing Hollow Rear Brake Kit for the Cadillac CTS (2008-2013) addresses the rear specifically, where a heavy RWD or AWD sedan does more of its braking work than owners expect.

This is a rear big brake kit built for drivers running the CTS hard on fast road and circuit, not a cosmetic swap. Supplied as a matched left-and-right pair, the two-piece hollow-vane discs trim rotating and unsprung mass at each rear corner while opening up cooling, so the rear axle holds its bite when the car is working.

What this brake kit does for your 2008-2013 Cadillac CTS

The first thing you feel is a firmer, more consistent pedal once the rear stops fading on the third or fourth hard stop. Lighter two-piece discs cut rotating and unsprung mass at the rear hubs, which sharpens response and eases the load on the rear dampers over broken surfaces. Three pad compounds, Street, Sport and Racing, let you match the rear bite to how you actually drive the CTS, from quiet, low-dust daily commuting to repeated circuit braking where the Racing compound earns its keep. Because the kit reduces rear heat build-up, the whole car settles better into a corner under trail braking, with less of the nervousness a heavy sedan shows when the back brakes are cooked, and matching the rear compound to the front keeps the brake balance true. Painted caliper colours, Red, Yellow, Gold, Black or Anodized Black at no extra cost, mean the upgrade looks deliberate behind the wheels.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from the lightweight hollow-vane disc construction, which cores mass out of the braking ring without giving up swept area, so the rear axle sheds heat faster and recovers between stops. The disc is a two-piece floating design, so the ring can expand under heat without distorting the bell. It pairs those discs with an upsized rear caliper to deliver the bigger, more progressive rear clamp a heavy CTS benefits from. The caliper body is hollow-cast as standard, with a Hollow Racing upgrade available for serious track use that removes the dust cover, is rated to 1000C and carries a two-year warranty. The compound choice is the part most owners underrate: Street for quiet, low-dust road manners, Sport for spirited fast-road use, and Racing for track days where pad fade is the limiting factor. Painted finishes cover everything from a subtle Anodized Black to a bold Gold, with premium polished-forged and candy options and a custom Pantone choice to match the car, while discs can be drilled or slotted at the same price, braided lines are included, and the centre bell can be upgraded to a two-tone anodized colour or titanium. The kit is engineered as a rear-axle upgrade, so it complements a front big brake setup rather than overwhelming the balance.
