Caliper render for this kit:

The Mitsubishi Grunder’s front-wheel-drive platform loads the nose axle heavily on every deceleration, with factory hardware calibrated for an executive saloon’s touring brief rather than the spirited pace the 3.0-litre V6 variants are capable of sustaining across a demanding mountain road or a long motorway exit. Where the standard setup starts to fade under repeated hard stops, the front end is doing the most work and receiving the least help.
This XYZ Racing Hollow Front Brake Kit addresses the front axle directly. It is a front-axle upgrade, a matched pair of left and right front calipers and discs, with three pad compounds, Street, Sport and Racing, covering the spectrum from daily replacement performance to full competition use. Included caliper colours mean the installation reads as a considered upgrade rather than a purely functional swap.
What this brake kit does for your 2004-2012 Mitsubishi GRUNDER
The Grunder’s FWD layout concentrates braking load at the nose; there is no rear axle sharing the work in the same proportion you get from an all-wheel-drive or rear-driven platform. The hollow-vane disc construction pulls heat out of the disc body far faster than the solid OE item and trims rotating and unsprung mass off the front axle, shifting the front end’s thermal capacity meaningfully. Street is the quiet, low-dust road default for owners replacing ageing OE hardware with something of comparable character but better consistency over repeated stops. Sport gives a confident, higher-temperature pedal on demanding back-road use. Racing is there for owners who take the car to track days or hillclimb events. Caliper colour is included at no extra cost in Red, Yellow, Gold, Black and Anodized Black, so the upgrade shows through the wheel spokes for those who want it to.
About the Hollow Front Brake Kit
The Hollow Front Brake Kit is XYZ Racing’s direct-fit front-axle upgrade for platforms where the OE braking package underperforms relative to the car’s weight and power. The caliper is hollow-bodied as standard, paired with two-piece floating discs available drilled or slotted at the same price, plumbed on braided lines for a firm pedal. It is configured at order around the buyer’s actual use: Street for replacement-level daily driving, Sport for spirited road use and occasional circuit sessions, and Racing for track-focused builds with sustained hard-braking demands. For serious track use an optional Hollow Racing caliper upgrade is offered, run without a dust cover, rated to 1000C and backed by a two-year warranty. Caliper finish is included in Red, Yellow, Gold, Black and Anodized Black, with a Custom Color to any Pantone for £150, premium polished-forged Titanium, Polished Gold and Polished Silver, and candy Teal, Blue, Red and Orange. The front-specific fitment matches the load distribution of FWD platforms, where the nose absorbs the dominant proportion of braking force on any deceleration.

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.
