Do the Endless Brake Pads for Ferrari 308 fit the Quattrovalvole?

No. These Brake Pads for Ferrari 308 two-valve cars use EIP003 front and EIP013 rear, as Endless lists for the GT4, GTB and GTS up to 1982. The GTB and GTS Quattrovalvole of 1982 to 1985 takes a different front shape, EIP016, sold on its own listing. If in doubt, send Bulletproof Automotive a photo of the front calipers.

Are the 308 GTBi and GTSi covered?

Yes. The fuel-injected GTBi and GTSi built from 1980 to 1982 are two-valve cars, inside the 1975 to 1982 range Endless gives for the GTB and GTS. They take the same EIP003 front and EIP013 rear shapes as the carbureted cars and the GT4.

Which Endless compound suits a classic 308 on the road?

SSM Plus suits most road-driven 308s. Endless rates it for low dust, low noise and long life, with braking that builds with pedal pressure, which feels natural in an older car. MX72 is the alternative for a driver who wants more friction at low temperatures, as on the first stops of a drive, while still keeping noise and dust to a minimum.

What should a 308 run for track days or historic racing?

On street tires at track days, MX72 Plus is the compound to start with, and Endless rates it to 750C, or 1382F. CC-Rg, rated to 800C, or 1472F, suits a car on circuit most months but is noisy on the road. A 308 prepared for historic racing can use the Racing Group, W003 or S330, and Bulletproof Automotive confirms the exact racing compound on the order.

Is the Front and Rear Set cheaper on a 308?

No. Endless offers no combo price for EIP003 and EIP013, so the Front and Rear Set costs the same as one front set plus one rear set. It is still the simplest way to order the same compound at both ends, and each axle set covers both wheels on that axle.

Endless Brake Pads for Ferrari 308 GTB, GTS and GT4 2-Valve

Endless’s Brake Pads for Ferrari 308 GTB, GTS and GT4 2-Valve fit the transverse V8 cars built before the Quattrovalvole arrived in 1982: the 2+2 GT4, the GTB and the targa-topped GTS, including the fuel-injected GTBi and GTSi of 1980 to 1982. Endless gives each axle its own shape, EIP003 at the front and EIP013 at the rear, and lists a separate front shape for the four-valve cars, so the cylinder head is the thing to check before ordering. For a 308 used on the road, SSM Plus is our recommendation; one that sees track days on street tires is better served by MX72 Plus.

Features

Endless pad shapes EIP003 front and EIP013 rear for the two-valve 308
Four street and street-to-track compounds: SSM Plus, MX72, MX72 Plus and CC-Rg
Seventeen racing compounds in three options: the Racing Group, W003 and S330
Every compound offered per axle or as a Front and Rear Set

Choosing a Compound

Endless offers every compound for both EIP003 and EIP013, so a two-valve 308 can run the same material at each end. SSM Plus suits a car used for touring and shows, and keeps dust off the wheels. MX72 is the pick for spirited road driving, with better bite from cold, and MX72 Plus for a 308 that does track days on street tires. CC-Rg makes sense only for a car on circuit regularly, given its road noise, and the racing compounds are for cars prepared for historic racing.

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.

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.
