Which compound suits a Cobalt SS at autocross and track days?

MX72 for autocross and quick road driving, with strong friction at low temperatures, and MX72 Plus for track days on street tires, which Endless rates to 750C, or 1382F. A Cobalt that laps most months moves to CC-Rg, rated to 800C, or 1472F, with high bite from cold, though Endless notes it is noisy on the street.

Will SSM Plus cut brake dust on a daily-driven Cobalt SS?

Yes. Endless rates SSM Plus for low dust, low noise and long life, and it builds braking with pedal pressure instead of grabbing at the first touch, which makes for smooth stops in traffic. It works from 0 to 550C, or 32 to 1022F, enough for brisk road driving. SSS is not priced for this shape, so SSM Plus is the cleanest option.

Is S55G a good racing compound for a front-wheel-drive car?

Yes. Endless describes S55G as suiting lightweight and front-wheel-drive cars, and the rear of front-wheel-drive cars, with high controllability, and it is one of the fifteen compounds in the Racing Group. Name it in the order notes and Bulletproof Automotive confirms it with your order. Like every racing compound, it needs the Endless bedding procedure before hard use.

Do these pads fit a Cobalt with aftermarket calipers?

No. EIP191 is the shape for the factory Brembo four-piston front calipers. A Cobalt converted to another caliper needs the pads made for it, which may be a different Endless shape or none at all. Tell Bulletproof Automotive the caliper brand and model, or send a clear photo, and we can confirm which pads to order.

Endless Brake Pads for Chevrolet Cobalt SS Turbo

Endless’s Brake Pads for Chevrolet Cobalt SS Turbo fit the front axle of the 2008 to 2010 Cobalt SS, the 260-horsepower, 2.0-liter turbocharged car Chevrolet sent out with four-piston Brembo front calipers. Endless supplies the front as EIP191, a shape it also lists for the front of the Alfa Romeo MiTo. A front-wheel-drive car does most of its stopping at the front, so the front compound sets the character of the brakes: SSM Plus for daily driving, MX72 for a car that also autocrosses, and MX72 Plus for track days on street tires.

Features

Endless front pad shape EIP191, for the Brembo four-piston front calipers
Street and street-to-track compounds SSM Plus, MX72, MX72 Plus and CC-Rg
Racing compounds in four options: the fifteen-compound Racing Group, W003, S330 and MA45B
Sold as a front set covering both wheels on the front axle

Choosing a Compound

For a Cobalt SS used every day, SSM Plus is the sensible pick, quiet and easy on the wheels; Endless does not price SSS for this shape. MX72 suits spirited road driving and autocross, MX72 Plus suits track days on street tires, and CC-Rg suits a car that runs on track most months. Among the racing options, S55G in the Racing Group is the compound Endless points at front-wheel-drive cars, and it is where a prepared Cobalt should start. MA45B, the endurance compound, is far more than a track-day Cobalt needs. W007 and W008 are left off because Endless designs both for carbon ceramic rotors, and the Cobalt 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.

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.
