Which model years do the Endless Brake Pads for 8L cover?

Endless lists EIP024 front and EIP025 rear for the 8L S3 from 1999 to 2001. Audi kept building the car into 2003, but Endless does not list those later cars, so the owner of a 2002 or 2003 S3 should ask Bulletproof Automotive to confirm fitment before ordering these Brake Pads for 8L hatchbacks.

Which compound should an S3 run at a track day?

Start with MX72 Plus. Endless rates it to 750C, or 1382F, and aims it at cars on street tires that see circuit time, so it suits an S3 doing a handful of events a year. Owners on track most months step up to CC-Rg, good to 800C, or 1472F, accepting that Endless calls it noisy on the street.

Is SSS available for the S3?

No. Endless does not make SSS in the EIP024 or EIP025 shapes, so the cleanest and quietest option here is SSM Plus. Endless rates SSM Plus for low dust, low noise and long life, with braking that builds smoothly as pedal pressure rises, which suits an S3 used every day in traffic.

Why is MA45B sold for the rear axle only?

Endless prices its MA45B endurance compound for the EIP025 rear shape but not for the EIP024 front, so Bulletproof Automotive can only offer it as a Rear set. Endless designs MA45B for long races, with low but stable friction and strong wear resistance, so it suits a car built for endurance events rather than the road.

Do the racing compounds need bedding in?

Yes. Endless sets one procedure for all of its racing compounds. Brake at 70 to 80 percent of normal pedal effort and bring the rotors up gradually to 400C, or 752F, then let them cool below 150C, or 302F, before any hard use. Do it before the first timed session, not during it.

Endless Brake Pads for 8L Audi S3

Endless’s Brake Pads for 8L Audi S3 fit the first S3, the 1.8-liter turbocharged quattro hatchback that Audi never sold new in the US. Endless lists EIP024 at the front and EIP025 at the rear for 1999 to 2001 cars, and its catalogue notes that both shapes also serve the A3, A4, Golf and Passat of the period, so the S3 rides on familiar Volkswagen Group hardware rather than anything rare. For a road-driven S3, MX72 is the compound we would fit; MX72 Plus is the better call once the car starts doing track days.

Features

Endless pad shapes EIP024 front and EIP025 rear, listed for the S3 from 1999 to 2001
Four street and street-to-track compounds: SSM Plus, MX72, MX72 Plus and CC-Rg
Fifteen racing compounds in the Racing Group, with W003 and S330 sold on their own
MA45B endurance compound offered for the rear axle only
Each other compound sold as a Front set, a Rear set or a Front and Rear Set

Choosing a Compound

On an 8L S3 used as a quick road car, MX72 is the natural fit: Endless gives it strong friction from cold with little noise or dust. SSM Plus is the cleaner, quieter choice for a car that mostly commutes, and Endless does not make SSS in these shapes. MX72 Plus and CC-Rg suit an S3 that laps a circuit on a regular basis, while the racing compounds belong on a prepared car. MA45B is rear only because Endless does not price it for EIP024. W007 and W008 are left off because Endless designs both for carbon ceramic rotors, and the S3 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 rear axle only on this car.

Notes

Each Front or Rear set of Brake Pads for 8L S3s covers both wheels on one axle
Endless lists these shapes for 1999 to 2001 cars. Owners of a later 8L S3 should check with Bulletproof Automotive before ordering.
Not for the 8P S3 of 2006 to 2012 or the 8V S3, which take different Endless pads
For the factory calipers; an S3 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.
