Caliper render for this kit:

The E82 135 carries its turbocharged straight-six well forward of the front axle, and on a short-wheelbase rear-drive coupe that nose-heavy bias loads the rear end hard under trail braking and on corner exit. The standard rear setup was specified for a car making far less than the 135’s 300-plus bhp, and it tells on a second or third hard lap. This XYZ Racing rear brake kit for the Bmw 1 Series E 82 135 (OE185) addresses the axle that quietly does the most work on a fast 1 Series.
Built around two-piece floating, lightweight discs, this rear big brake kit cuts rotating and unsprung mass at the back wheels while giving the rear pads a larger, more thermally stable surface to bite. For a 2007-2013 135 used on track days, B-road runs, or both, it restores the braking margin the chassis was always able to use.
What this brake kit does for your 2007-2013 Bmw 1 Series E 82 135 (OE185)
You feel this kit most where the standard rears struggle: late, hard braking from the 135’s considerable straight-line pace into tighter corners. The two-piece floating discs shed heat faster and add less rotating mass, so pedal feel stays firmer through a session instead of going long and wooden. With a choice of Street, Sport, or Racing pad compounds, you can match the rear bite to how the car is used, from a daily that sees occasional spirited driving to a dedicated track 1 Series. The result is a more stable platform under braking, cleaner rotation into the apex, and the confidence to lean on the rear axle without cooking it.
About the Rear Brake Kit
The XYZ Racing rear brake kit is a rear-axle upgrade supplied as a matched pair of left and right rear calipers and discs, built around two-piece floating, hollow-vane discs that strip weight from the rotating assembly without sacrificing thermal capacity. Less rotating mass at the back helps the suspension control the wheel over kerbs and broken surfaces, while the disc design spreads heat more evenly to resist fade under repeat stops. Discs come drilled or slotted at the same price, fed by braided lines. The forged caliper is hollow-body as standard, with an optional Hollow Racing upgrade (no dust cover, 1000C rated, two-year warranty) for sustained circuit abuse. The kit comes with a choice of three pad compounds, Street for road use, Sport for fast-road and light track work, and Racing for the hardest sessions, so the friction package can be specified to the job. Included painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge, plus premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes. Two-tone centre bells in five anodized colours, or titanium, are selectable at checkout. Everything is sized for the rear axle of the E82 platform rather than adapted from a generic fitment.

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 330–356mm (rear). 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.
