Caliper render for this kit:
Hand-assembled by BMW Motorsport at Garching and weighing over 1,600kg, the E34 M5 has always been a car that works its front brakes hard. The S38 straight-six, available in 3.6-litre S38B36 and later 3.8-litre S38B38 form across the 1988-1995 production run, sits well ahead of the front axle centreline, loading the front tyres heavily under deceleration and meaning the front braking hardware carries a disproportionate share of the work. On cars now over thirty years old, original equipment in this area has had every opportunity to fall short of what the S38’s performance demands.
The XYZ Racing Hollow front brake kit is a direct upgrade and replacement for the E34 M5: a single-axle front kit, a left and right pair of calipers on two-piece floating discs, configured at the configurator above with a choice of three pad compounds and a full caliper colour range.
What this brake kit does for your 1988-1995 Bmw 5 SERIES E 34 M5
Because the E34 M5’s weight sits nose-forward and trail-braking loads the front axle significantly, the quality of the front braking system has an outsized effect on corner-entry feel and stopping confidence. Fresh hardware restores the pedal response that decades of thermal cycling and wear have taken from original equipment, and the two-piece floating discs reduce unsprung and rotating mass while letting the friction ring expand without coning under heat. The three compound grades address how the car is actually used: Street is the quiet, low-dust default for road cars covering typical UK miles, Sport handles fast-road and occasional track use where temperatures climb but sustained heat build-up is not the dominant concern, and Racing is suited to club events and sprint days where the S38’s torque generates repeat high-temperature stops. Caliper colours, from the included no-cost painted finishes through to premium polished and candy options, allow the front end to be specified to match or contrast with the car’s overall finish.
About the Hollow Front Brake Kit
The XYZ Racing Hollow is the brand’s front brake package for the E34 M5, supplied as a complete front-axle assembly rather than individual wear items. The caliper is hollow-bodied as standard, keeping weight low at each front corner, and for a car that may still be running its original brake hardware after three decades, treating the system as a whole rather than replacing components individually is the more coherent approach. For hard circuit work the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Compound selection is confirmed at the ordering stage: Street, Sport, and Racing grades cover road-biased use, fast-road and occasional circuit work, and full track-day or competition use respectively. Disc style is drilled or slotted at the same price, centre bells upgrade to two-tone anodized in five colours or to titanium, and the caliper colour programme runs from the included Red, Yellow, Gold, Black, and Anodized Black through a Custom Color in any Pantone, premium polished Titanium, Polished Gold, and Polished Silver, and candy Teal, Blue, Red, and Orange, all selected in a single transaction. The kit covers the front axle only.
Fitment for the Bmw 5 SERIES E 34 M5 (1988-1995)
This kit is specified for the BMW 5 Series E34 M5 across the full production span from 1988 to 1995, covering both the 3.6-litre S38B36 and the later 3.8-litre S38B38 variants. The M5’s front braking hardware differs from standard E34 five-series specification, and the fitment data supplied reflects M5 dimensions throughout, so confirm the chassis code and front hub spec of your specific car 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.
