Caliper render for this kit:
The G35 4D is a heavier proposition than the G35 coupe on the same V35 platform: the additional body structure and four-door rigidity add meaningful mass to the nose, and the VQ35DE has enough pull to make that thermal load conspicuous under heavy braking. The standard front brake specification was sized for a sporting road car, not for the sustained demands a circuit session or an aggressive mountain road places on front-axle hardware. Heat soak in the stock setup arrives faster than the chassis’s capability runs out.
This XYZ Racing front big brake kit replaces the front-axle hardware with a system built to a higher thermal and mechanical standard, giving the V35 sedan the stopping authority its chassis balance deserves. It is a front-axle kit, a matched left and right pair of calipers and two-piece floating discs. On a rear-drive platform with this weight distribution, the front end carries the braking load disproportionately, and the OE brakes leave that potential partially unexploited.
What this brake kit does for your 2003-2006 Infiniti G35 4D
Larger swept area at the front axle raises the thermal ceiling before fade sets in, immediately noticeable on a hard road drive where the standard discs begin to betray themselves through a softening pedal mid-session. The hollow-vane disc routes air through its internal structure to shed heat faster, and the two-piece floating construction keeps the iron ring flat as it heats so the disc resists coning. The VQ35DE pulls the G35 4D strongly through the upper rev range, and having braking hardware that matches that capability closes a gap most owners only notice when the standard system gets fully worked. Three pad compounds reflect that not every G35 4D sees a circuit: Street, quiet and low-dust, suits the fast-road car; Sport bridges regular track attendance and daily driving; Racing is for when the sedan is committed to circuit work and the pad needs to operate consistently within a defined thermal band. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone, letting the visible front hardware match the build.
About the Hollow Front Big Brake Kit
The kit targets the thermal shortfall in performance sedans the factory brake specification was never designed to handle. The front kit is built around the G35 4D’s 2003-2006 front-axle geometry, fitting the V35 platform without hub adaptors or clearance compromises that frequently afflict aftermarket brake upgrades. The hollow-vane disc is available drilled or slotted at the same price, and the caliper is a hollow-body forging as standard, with an optional Hollow Racing upgrade for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Three pad grades cover a genuine spectrum of use: Street for the dual-purpose car that rarely sees a circuit, Sport for the owner who runs track days without a dedicated second set of wheels, and Racing for builds where consistent thermal performance under circuit conditions matters more than cold-bite on the daily. Caliper finish extends beyond the no-cost painted colours to premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange, with two-tone or titanium centre bells, all selectable at checkout.
Fitment for the Infiniti G35 4D (2003-2006)
Confirmed for the Infiniti G35 4D across the full 2003 to 2006 production span, the V35 sedan in its original generation, before the revised 2007 specification. This is a front-axle kit for the standard rear-wheel-drive 3.5-litre sedan; confirm your current front wheel diameter and verify there are no non-standard hub components in place 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.
