Are the Endless Brake Pads for R170 cars listed for the SLK230 and SLK320?

No. Endless lists this pair for the 2002 to 2004 SLK32 AMG, which AMG fitted with larger brakes than the regular SLK models. An SLK230 or SLK320 owner should send Bulletproof Automotive the year and a photo of the front caliper, and we will check which Endless pads suit the car before an order is placed.

Which Endless compound suits an SLK32 on fast road drives?

MX72. It works from 50C, or 122F, to 700C, or 1292F, with strong friction from cold, minimal noise and dust, and less rotor wear than a typical semi-metallic pad. That suits an SLK32 driven quickly on back roads. SSM Plus is the gentler option for a car that commutes, and MX72 Plus is the move for track days.

Which pads should an SLK32 run for regular track days?

CC-Rg. Endless rates it from 50C, or 122F, to 800C, or 1472F, with high initial bite across that range and modulation that works with the factory ABS under hard use. It is noisy on the street, so an SLK32 that sees only a couple of events a year is better served by MX72 Plus, rated to 750C, or 1382F.

Is the Front and Rear Set cheaper than two axles bought separately?

No. Endless does not offer a combo set for EIP046 and EIP051, so the Front and Rear Set costs the same as a Front set plus a Rear set in every compound. It is still the simple way to order matching pads for the whole car, and each set inside it covers both wheels on one axle.

Will Endless pads leave a lot of brake dust on SLK32 wheels?

No. SSM Plus is the low-dust choice, rated by Endless for low dust, low noise and long life, and the Endless Brake Pads for R170 cars in MX72 and MX72 Plus also keep dust to a minimum. CC-Rg is the street-capable compound Endless describes as noisy on the road, and the racing compounds are built for the circuit.

Endless Brake Pads for R170 Mercedes-Benz SLK32 AMG

Endless’s Brake Pads for R170 Mercedes-Benz SLK32 AMG fit the supercharged 3.2-liter M112 V6 roadster that Mercedes built from 2001 to 2004, of which 2,056 came to the US. Endless lists EIP046 at the front, a shape it also refers to the W210 E-Class, and EIP051 at the rear, which it refers to the W203 C-Class and W210, for 2002 to 2004 cars. Every SLK32 was an automatic, and AMG gave it larger brakes than the regular SLK. Options on these shapes reach from quiet road compounds to full competition materials. For an SLK32 driven hard on back roads, MX72 is our pick.

Features

Endless pad shapes EIP046 front and EIP051 rear for the 2002 to 2004 SLK32 AMG
SSM Plus, MX72, MX72 Plus and CC-Rg, from quiet road use to regular track days
Racing Group of fifteen compounds, with W003 and S330 offered on their own
Each compound sold as a Front set, a Rear set or a Front and Rear Set

Choosing a Compound

For an SLK32 used on the road, SSM Plus keeps the wheels clean and the car quiet; Endless does not price SSS for these shapes. MX72 is the better fit for an owner who drives quickly and wants stronger bite from cold. MX72 Plus covers track days on street tires and CC-Rg covers a car that laps regularly. The racing compounds are for an SLK32 prepared for competition, and MA45B is not offered because Endless does not price it for EIP046 or EIP051.

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.

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.
