Caliper render for this kit:
The second-generation 9-3 Aero carries most of its mass over the front axle, and Saab specced the rear brakes to match: modest discs that do little of the actual stopping work. The XYZ Racing rear brake kit for the Saab 9-3 2.8T AERO tackles that imbalance directly, giving the back axle the bite it needs to settle the car under hard deceleration.
This is a rear-axle upgrade for owners who lean on the 2.8T V6 on a fast road or the occasional track day, where the standard rear setup runs out of heat capacity and the front discs end up doing everything. It supplies a matched pair of rear calipers and two-piece floating discs. With the right pad compound behind it, the 9-3 stops shorter, rotates more willingly into a corner, and keeps its composure through a sequence of hard stops.
What this brake kit does for your 2005-2010 Saab 9-3 2.8T AERO
On a heavy, turbocharged Saab that carries executive-saloon mass, braking balance is everything. Adding genuine rear stopping power shifts some of the workload off the front discs, which on the 9-3 Aero are the first components to overheat on a quick B-road. The three pad compounds let you match the rear axle to how you actually drive: Street for daily refinement and low dust, Sport for harder road use with the odd lap, and Racing for track sessions where heat is the enemy. A more capable rear end also steadies the car under trail-braking, taking the edge off the nose-led understeer the 9-3 is known for and giving you a more neutral turn-in.
About the rear big brake kit
XYZ Racing supplies the rear brake kit as a complete bolt-on package for the back axle, with a pair of calipers, two-piece floating discs and pads to suit your chosen compound. The two-piece floating disc is the heart of it: a hollow-vane friction ring that sheds heat far faster than the solid factory item, mounted to an alloy bell that lets it expand under load without warping, which is exactly what a turbocharged car of this weight asks for when it works its brakes hard. Drilled or slotted faces are available at the same price. The compound range runs from Street for everyday driving, through Sport for committed road use, to Racing built to hold its bite at track temperatures. Caliper bodies are hollow-cast as standard, with an optional Hollow Racing upgrade for owners who run the car on circuit, removing the dust cover, rated to 1000C and warrantied for two years. Calipers are finished in your choice of Red, Yellow, Gold, Black or Anodized Black at no extra cost, with custom Pantone matching available. Everything is sized to mount to the 9-3 Aero’s rear hubs without modification.
Fitment for the Saab 9-3 2.8T AERO (2005-2010)
This kit is cut specifically for the 2.8T V6 Aero version of the second-generation Saab 9-3, covering the 2005 to 2010 model years. It fits the rear axle only and is matched to the Aero’s hub and mounting points. Confirm your build year and that yours is the 2.8T Aero before ordering, as lesser 9-3 variants run different rear brake hardware.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.
Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).
Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
