Caliper render for this kit:
Built on Mercedes-Benz’s MFA architecture, the Q30 arrived with a brake specification shaped by comfort-first priorities, which is fine until you start using the 2.0T Sport the way its chassis tempts you to. Front-biased weight distribution loads the front axle hard under repeated braking, and once the factory discs have absorbed a few spirited passes, the pedal tells the story.
The XYZ Racing front big brake kit gives 2015-2019 Q30 owners a direct route out of that limitation. It is a front-axle kit: a matched pair of front calipers and two-piece floating discs that bolt straight onto the standard hubs. Three pad compounds and a deep set of caliper finishes mean you build it to suit the car when you order, rather than accepting whatever grey the factory left behind.
What this brake kit does for your 2015-2019 Infiniti Q30
The two-piece floating disc uses a hollow-vane rotor to reduce both unsprung and rotating mass at the front axle while opening more surface area to airflow. Heat from repeated hard stops disperses faster than through a standard vented disc, so on a nose-heavy platform like the Q30 the braking window before fade sets in extends noticeably. The lighter rotating assembly also sharpens steering response, because there is less inertia for the front suspension to fight.
Pad choice sharpens it further. Street is the quiet, low-dust road default. Sport adds bite and heat range for fast-road use with the occasional track day. Racing is the full track compound for circuit work where the front wheels load hard from corner entry onward. You select the compound when you order, so the pad is matched to how the car is actually used.
About the front big brake kit
The caliper is a hollow-body forged unit as standard, paired with the two-piece floating disc in your choice of drilled or slotted finish at the same price. Braided lines come as part of the kit, giving a firmer, more consistent pedal than the factory rubber hoses. For serious track use there is an optional Hollow Racing caliper upgrade, which deletes the dust cover, is rated to 1000C and carries a two-year warranty.
Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. A Custom Color in any Pantone shade is available for an additional £150. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, and the premium candy range runs Candy Teal, Candy Blue, Candy Red and Candy Orange. Centre bell upgrades are offered as two-tone anodizing in five colours, or titanium, all selectable at checkout.
Fitment for the Infiniti Q30 (2015-2019)
This kit covers the Infiniti Q30 across the model’s full production run from 2015 to 2019, spanning petrol and diesel variants and both front-wheel and all-wheel drive drivetrains. Buyers should confirm their front hub dimensions and caliper carrier clearance against the kit specification before ordering, particularly given the platform’s shared-component heritage. Pad compound and caliper colour are both selected at checkout.

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.
