Do the Endless Brake Pads for E85 fit the Z4 M Roadster?

No. The Endless Brake Pads for E85 and E86 cars on this listing are for the 3.0si. Endless gives the Z4 M Roadster and M Coupe the same EIP017 front shape but a different rear, EIP053, so an M car needs the pads from its own listing. Order from the Z4 M listing for either of those cars.

Do these pads fit both the 3.0si roadster and coupe?

Yes. Endless lists EIP017 front and EIP021 rear for the 3.0si in both body styles from 2006 to 2008, so the E85 roadster and the E86 coupe take the same pads. The Z4 M versions of each body are the exception, as they use a different rear shape, and Endless does not list the 2.5i or 3.0i.

Which compound suits a Z4 3.0si at track days?

MX72 Plus suits a 3.0si on street tires at a few events a year, and Endless rates it to 750C, or 1382F. An owner on track most months should consider CC-Rg, rated to 800C, or 1472F, with high initial bite even when cold, accepting the road noise Endless notes. The racing compounds are for a car prepared for competition.

Why is MA45B only offered for the front of the 3.0si?

Endless prices its endurance compound for the EIP017 front shape but not for the EIP021 rear, so Bulletproof Automotive can offer it for the front axle only. Owners who want one racing compound at both ends can choose from the Racing Group, W003 or S330, all of which Endless makes for both shapes.

Which Endless pad keeps a Z4 3.0si cleanest?

SSM Plus. It is the low-dust, low-noise compound in this range, with long life and a progressive feel as pedal pressure rises, which suits a roadster or coupe used for relaxed weekend drives. Endless does not make SSS in these shapes. MX72 is the step up for brisk driving and still keeps noise and dust to a minimum.

Endless Brake Pads for E85 / E86 BMW Z4 3.0si

Endless’s Brake Pads for E85 / E86 BMW Z4 3.0si suit the 2006 to 2008 roadster and coupe powered by the 3.0-liter N52 six, the most powerful Z4 below the M models. Endless gives the 3.0si EIP017 at the front, the same shape it lists for the E46 M3 and the Z4 M, and EIP021 at the rear, where the M cars take EIP053 instead. That split matters when ordering: a 3.0si and a Z4 M share front pads but not rear ones. For a 3.0si driven hard on the road with occasional track days, MX72 Plus is our recommendation.

Features

Endless pad shapes EIP017 front and EIP021 rear for the 3.0si roadster and coupe
SSM Plus, MX72, MX72 Plus and CC-Rg for both axles
Racing Group of fifteen compounds, plus W003 and S330 as single options, for either axle
MA45B endurance compound offered for the front axle
Front and Rear Sets in every compound except MA45B

Choosing a Compound

A 3.0si used for weekend drives is best on SSM Plus, as Endless does not make SSS in these shapes. MX72 suits brisk road driving, MX72 Plus suits a coupe or roadster that runs track days on street tires, and CC-Rg suits one on the circuit most months. The racing compounds are for a prepared car, and MA45B is front only, because Endless does not price it for the EIP021 rear shape. W007 and W008 are left off because Endless designs both for carbon ceramic rotors, and the Z4 3.0si runs iron rotors.

Every figure below is Endless’s own. Friction is the compound’s average friction coefficient, so a higher number gives more bite for the same pedal pressure. The rotor range is the band of rotor temperatures Endless designs the compound to work in, so choose by the temperatures your car will see.

Street and street-to-track compounds

SSM Plus (street): non-asbestos; friction 0.33-0.40; rotor range 0-550C (32-1022F). Low dust, low noise and long life. Braking builds with pedal pressure rather than a sharp first bite, for drivers who want clean wheels and a quiet car.
MX72 (street to light track): ceramic carbon metal; friction 0.37-0.47; rotor range 50-700C (122-1292F). Minimal noise and dust, strong friction at low temperatures, reduced rotor wear and a better pedal feel than a typical semi-metallic pad. Endless’s dual-duty compound for a road car that sees the occasional track day.
MX72 Plus (street to circuit): ceramic carbon metal; friction 0.39-0.47; rotor range 50-750C (122-1382F). Holds its braking force to higher temperatures than MX72, with stable control and a consistent pedal release. Endless aims it at cars on street tires that run on track.
CC-Rg (track day, street capable): ceramic carbon metal; friction 0.38-0.45; rotor range 50-800C (122-1472F). High initial bite across a wide temperature range, even when cold, and modulation that works with the factory ABS under hard use. Endless notes it is noisy on the street; it is the step up from MX72 Plus for regular track days.

Racing compounds

Each option below is one choice in the Choose Compound menu. For a group, name your compound in the order notes and Bulletproof Automotive confirms it with your order. Every racing compound needs Endless’s bedding procedure: at 70 to 80 percent of normal pedal effort, bring the rotors gradually to 400C (752F), then let them cool below 150C (302F) before hard use.

Racing Group

ME22: dual braking style; friction 0.33-0.38; rotor range 150-800C (302-1472F). Developed from ME20 with lower friction for control, for light to mid-weight cars or heavier cars on slower circuits. Endless rates it for street and track.
ME20: trail-braking style; rotor range 150-800C (302-1472F). High, stable friction at high temperature with low wear, developed for touring cars and rally. Works front or rear, with stock or racing ABS.
N35S: trail-braking style; rotor range 300-800C (572-1472F). Quick, sharp and responsive, with stable modulation under high temperature and load. Endless’s flagship rally compound, also run in FIA GT, and its suggested starting point for drivers new to Endless racing pads.
N05U: trail-braking style; friction 0.46-0.53; rotor range 300-800C (572-1472F). More bite than N35S, popular in sprint-focused Porsche Cup cars.
N05S: trail-braking style; friction 0.45-0.53; rotor range 300-800C (572-1472F). Immediate high friction with little pedal effort, used in Japanese rally cars without brake boosters and in European and Australian sprint racing.
N30C: friction 0.50-0.60; rotor range 300-800C (572-1472F). High initial bite, gentle on rotors and low wear. A rally compound for cars without a brake booster.
MS20: friction 0.32-0.38; rotor range 150-800C (302-1472F). A low-friction rear pad with a flat torque curve and long life, for club racing cars.
MS25: friction 0.36-0.42; rotor range 150-800C (302-1472F). Warms up gradually even under heavy braking. Endless pairs it with a higher-friction pad to prevent lock-up.
MS35: friction 0.45-0.53; rotor range 300-800C (572-1472F). Mid to high initial bite with good modulation and control, a sprint pad for a wide range of conditions.
ML20A: friction 0.30-0.33; rotor range 300-800C (572-1472F). A rear compound with lower initial bite to prevent rear lock-up, for lightweight GT cars.
ML35A: friction 0.30-0.38; rotor range 300-800C (572-1472F). Slightly lower friction with excellent modulation and wear, for lighter GT cars.
ML40A: friction 0.32-0.47; rotor range 300-800C (572-1472F). Moderate friction that resists lock-up, an endurance compound.
S55G: Endless publishes no figures. It suits lightweight and front-wheel-drive cars, and the rear of front-wheel-drive cars, with high controllability.
PC35: Endless publishes no figures. More bite than N35S with high braking force and a stable pedal; Endless’s base pad for rally raid.
S41S: Endless publishes no figures. Developed for GT cars, including GT3, under high brake loads.

Sold as their own options

W003: trail-braking style; friction 0.40-0.45. Similar in character to N35S with better wear, tough and stable at high temperature with a linear torque curve; run in rally, touring cars, ALMS and PWC. Circuit only: Endless does not recommend it for the street and notes high rotor wear when cold.
S330: trail-braking style; friction 0.60-0.70; rotor range 300-850C (572-1562F). High friction for sprint racing, with good control at high levels and without accelerating rotor wear; run in Super GT, stock cars and GT2 and GT3 sprint racing.
MA45B: standard braking style; rotor range 300-800C (572-1472F). Endless’s endurance compound: low friction but stable for a whole race, with excellent heat resistance and wear. Most Nurburgring and Spa 24 Hours entrants run it. Offered for the front axle only on this car.

Applications

Notes

Each Front or Rear set of Brake Pads for E85 and E86 3.0si cars covers both wheels on one axle
Not for the Z4 M Roadster or Z4 M Coupe, which take EIP053 at the rear and have their own listing
Endless lists only the 3.0si; owners of a Z4 2.5i or 3.0i should check with Bulletproof Automotive
For the factory brakes; a car converted to an aftermarket big brake kit takes the pads for those calipers

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
