Caliper render for this kit:
For the 997 C4S, trail-braking is not an optional technique, it is the primary means of rotating a chassis that carries the majority of its mass behind the rear axle. That places front brake modulation at the centre of every fast corner entry: fade, or a bite point that shifts with heat, does not just cost time, it destabilises the balance the car depends on from apex entry through to mid-corner. The stock front setup handles road pace and occasional track use, but sustained circuit sessions expose its thermal ceiling.
This XYZ Racing front big brake kit for the Porsche 997 C4S (142) closes that gap. Built to fit 2006-2011 cars across both 997.1 and 997.2 production, it delivers substantially increased disc mass, hollow-vane construction for heat dispersal, and a three-compound pad programme spanning everyday road driving through to dedicated track use. The kit fits the front axle as a matched left and right pair with two-piece floating discs.
What this brake kit does for your 2006-2011 Porsche 997 C4S (142)
The C4S carries a weight premium over its rear-wheel-drive siblings by virtue of the Porsche Traction Management all-wheel-drive hardware, mass the front brakes encounter on every braking event and particularly significant under trail-braking into fast corners. The hollow-vane disc helps manage the heat that accumulates through repeated braking zones, maintaining consistent bite rather than allowing progressive fade to soften the pedal. Three compounds mean the same kit transitions from a Street specification that runs quietly in town through a Sport compound for spirited driving to a full Racing grade with the friction characteristics serious track work requires. Two-piece floating disc construction lets the friction ring expand and cool independently of the bell.
About the Hollow Front Brake Kit
This is a front-axle upgrade package combining three compounds with a full range of caliper colours. The hollow-vane disc is the defining design choice: material removed from the rotor reduces rotating mass without sacrificing the thermal capacity needed to handle repeated hard stops. The three-stage programme covers distinct contexts: Street is the low-dust everyday compound; Sport increases friction coefficient for committed fast-road driving; Racing is calibrated for the sustained high temperatures circuit sessions produce. The forged caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade for serious track use, rated to 1000C with no dust cover and a two-year warranty. Discs come drilled or slotted at the same price.
Included painted caliper colours are Red, Yellow, Gold, Black, and Anodized Black at no extra cost, with a Custom Color in any Pantone for builds around a specific livery or scheme, plus premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange).
Fitment for the Porsche 997 C4S (142) (2006-2011)
This kit is specified for the Porsche 997 Carrera 4S carrying the 142 chassis designation, covering production from 2006 to 2011, a span that encompasses both the 997.1 and the 997.2 generation of the wide-body Carrera 4S. Front axle fitment only. Confirm your chassis code against the 142 designation before ordering.

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 286–380mm (front). 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.
