2015 Nurburgring 24 Hour

2015 ADAC Zurich 24 Hours of Nurburgring

Congratulations to Belgian Team WRT (Drivers:Christopher Mies, Nico Müller, Edward Sandström and Laurens Vanthoor) for winning the 2015 Nurburgring 24 hour race. This is also the inaugural debut and first win of the new 2015+ spec Audi R8 LMS at the Nurburgring 24 hour event. This is the second consecutive time in 2 years that Audi Sport have won the 24 hour race at Nurburgring with the Audi R8 LMS platform. Audi Sport Team WRT completed an overall of 156 laps to win the tough 24 hour race which featured very close racing. With only a 40 second gap to second place, this year featured the closest finish ever for the 24 hour event.

Brembo Racing RB340

The Brembo RB340 material offers excellent wear resistance, high initial bite, stable friction levels (the performance does not degrade as much at elevated temperatures) and good modulation in a wide range of conditions. Brembo’s RB340 material is unique in construction as the optimal performance of the material is dictated by the energy of the brake system, not specifically the braking surface running temperature. This also means the material performance can be stable in a wide temperature range. The combination of wear resistance and a high initial attack means the driver does not need to use as much pedal effort to achieve the optimum stopping power and potentially fewer brake pad / disc changes in an endurance race.

2015 24 Hours of Nurburgring – Overview

The 24 hour endurance event which has been running since 1970 and is one of the most important races that car manufacturers running FIA GT3 based cars (which is increasingly becoming the global platform for GT racing) focus on. Many teams, car manufacturers (Examples: Audi, AMG, Porsche, Subaru, Hyundai) and technical suppliers even have facilities near the Nurburgring for extensive testing of professional racing and production based cars. The 2015 24 hour endurance event had over 150 entries which included factory supported FIA GT3 spec cars as well as privateer teams running cars such as the BMW E46 M3, Subaru Impreza WRX STi, Opel Astras and Volkswagen GTi which all race on the same circuit in separate classes.

The Nurburgring circuit is very difficult, fast, unforgiving and over 15 miles in length to complete one lap. 2015 featured several mandatory “slower speed zones” for driver and spectator safety as the modern GT3 specification cars are just as fast, if not faster than previous years in which they can easily hit 300 km/h plus on the straightaways. The reduced speed sections meant that teams could potentially add more down force and focus on overall grip versus overall top speed. With more down force comes the ability for higher braking performance. The 24 hour race always features changing grip levels on the track, slow & fast blind corners, rain, black ice and very fast straightaways which end in long as well as heavy brake zones. With the addition of “slow zones”, sudden traffic build up was a major factor as well especially at night-time. Brakes must offer a high level of performance, control, be consistent and have low wear (fewer pad changes in an endurance race means less time lost in the pits).

The Nurburgring circuit and the 24 hour race in Germany is regarded as one of the most demanding events in the world on teams, equipment, and drivers. It is the event where the latest and most cutting edge professional GT sports car technology is showcased.

Brake Fluid – Brembo Racing

Upgrading brake fluid for spirited, track or racing use is easily one of the most overlooked things when thinking of upgrading any component or part of the brake system.

Brake fluid performs a very critical function as it is the “life blood” of the brake system, as it is the foundation to hydraulically transfer brake pedal effort to the brake caliper’s pistons. Brake fluid also performs a vital function of lubricating caliper piston seals Brake fluid performance (or the lack of) can directly affect brake pedal feel, pressure and consistency through the operating temperature range. It is also one the most cost effective ways to improve brake pedal consistency (avoiding spongy pedal) under high temperature use.

Dry Boiling Point – Top professional racing teams purchase brake fluid based on several variables that include but are not limited to: dry boiling point, compressibility, viscosity, pedal feel, consistency, and its ability to recover after boiling. While dry boiling point is important, a lot of performance gain can be had from a fluid which has strengths in a lower fluid compressibility.

Most of the dry boiling points* of the top racing brake fluids sold to professional motorsport teams are rated very high so to have substantial gains in fluid performance, other factors can be the focus of development.

 * NOTE: The only way to verify the exact boiling point of a brake fluid is to test it in a fluid lab as there is no industry wide standardized testing for fluid. To properly compare fluids and have accurate results: the test has to be done at the same lab, with exactly the same environment and conditions.

Compressibility/Viscosity – A brake fluid with low compressibility offers a more positive pedal feel which is more consistent during brake applications.

Recovery – The fluid’s ability to recover to its most optimal performance after boiling is a crucial factor in brake fluid performance.

Street Use – Most professional racing fluids are not suitable and/or approved for street. The Brembo LCF600+ is DOT approved and is suitable for street and track use.

Brembo Racing brake fluids are proven motorsport brake fluids with low compressibility, high boiling points, even under the highest temperatures and demanding conditions.

Brembo Racing RB340

One of the top teams participating in the FIA WEC series is Larbre Competition, one of the only teams in the world racing with the Corvette platform as a non factory effort in the top level of professional motorsport. For 2015, Larbre Competition is racing a C7.R in the FIA WEC series.

The FIA World Endurance Championship (WEC) is starting to become the leading series by many car manufacturers and their technical partners to showcase new technologies in the LMP (Le Man Prototype) & GT (Grand Touring) Classes. The FIA WEC features endurance races (6 hour races and the 24 hours of Le Mans) and is a global series racing at challenging circuits in the United States, Europe, Asia and the Middle East. Stiff competition between factory run and private customer teams in all the various classes means teams choose to work with only the best technical partners to have the most competitive advantage.

Larbre Competition won class honors with a Corvette C6.R at the 24 hours of Le-Mans in 2012 using Brembo Racing RB340 brake pads. Larbre Competition also finished the 2012 Le Mans 24 hour race without changing brake pads or loss of performance through the race.

Brembo’s RB340 material is unique in construction and the optimal performance is dictated by the energy of the brake system, not so much the disc or pad direct running temperature. This means the material offers excellent wear resistance, high initial bite, stable friction levels (the performance does not degrade as much at elevated temperatures) and good modulation in a wide range of conditions. The combination of wear resistance and high initial attack means the driver does not need to push the brake pedal as hard to achieve the same stopping power. This is easier on the driver and means a common material can be potentially used for long and short races.

Brake pads and fluid are two very small things that make a huge difference that most people overlook. Pads and fluid help fine tune brake system characteristics like initial response, fade resistance, and pedal consistency. For an endurance race such as a 24 hour race, one of the many critical factors is the wear resistance of friction materials to avoid doing brake pad or rotor changes as this can cost valuable time in the pits. If changing pads or brake discs can be avoided altogether, this is the most ideal scenario.
