Fits Bmw 3 SERIES E 46 323 (1998-2006)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

330 mm

The E46 323’s 2.5-litre M52TU inline-six delivers its power with enough composure that the standard braking package, sized for road use and the occasional spirited B-road, tends to become the limiting factor before the chassis does. At the end of Donington’s Old Hairpin, or under sustained hard braking into a tighter infield complex, E46 323 owners know exactly what happens: the pedal firmness that was there on lap one has softened considerably by lap three. The XYZ Racing front big brake kit addresses that directly.

It is a single front-axle kit, a matched pair of calipers and two-piece floating discs. Three pad compounds, chosen when you order, let the specification match how you use the car, from mixed-road driving through to dedicated track days where the factory package runs out of thermal capacity well before the chassis does.

What this brake kit does for your 1998-2006 Bmw 3 SERIES E 46 323

The 323i occupies the lighter end of the E46 range. The 2.5-litre engine and the absence of M3-spec cooling and braking hardware mean the front axle carries less mass than a 330 or M3, but it also means the braking system was not built with sustained hard use in mind. Fitting the kit adds the swept area and thermal headroom the standard calipers lack. The hollow-vane disc moves cooling air through the rotor body and the two-piece floating ring grows under heat without coning, cutting rotating and unsprung mass at the same time.

Pad compound is set when you order. With Racing selected, the system handles the temperature cycles that would cause conventional pads to glaze or fade. Sport extends the performance window for owners who drive to the circuit and home again. Street delivers quiet, low-dust, road-focused bite for the 323 that stays out of the paddock. Braided lines firm the pedal, and discs come drilled or slotted at the same price. Caliper colour is included in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, giving E46 owners the ability to match the hardware to the car’s existing specification.

About the Hollow Front Brake Kit

The XYZ Racing kit applies a two-piece floating disc at the front axle, where reducing rotating and unsprung mass has the most direct effect on both braking response and steering feel. The caliper runs a hollow body as standard, keeping reciprocating weight low; for track and competition use a Hollow Racing upgrade drops the dust cover, is rated to 1000C and carries a two-year warranty. Three pad compounds are configurable at order: Street for road use, Sport for mixed-use driving, and Racing for applications where thermal performance across repeated hard braking is the priority. Caliper colour is selectable from the included painted finishes, with premium polished-forged and candy options and two-tone or titanium centre bells at checkout, giving the E46 owner control over the visual register of the brake package. As a front-axle fitment for the 323, this kit upgrades the part of the system that carries the heaviest load under hard deceleration.

Fitment for the Bmw 3 SERIES E 46 323 (1998-2006)

This kit is confirmed for the BMW 3 Series E46 323 covering the 1998 to 2006 model years. The E46 platform runs a consistent front strut geometry across the 316-to-330 range, and the XYZ-BRK-BKF-BM-020-FRONT is matched specifically to the 323 derivative. If the car has had previous suspension or hub work that altered the front geometry, confirm fitment compatibility 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.
