The 'Balance of Performance' as the success of SRO Motorsport


SRO Motorsport Group is one of the promoters more successful
the world of motor. A condition that is not casual, and is based on the
initial ‘BoP’, or what is the same, the well-known ‘Balance of
. This debugging system and a huge database enables you to find a
almost perfect balance among the various cars, and mechanical competing in
competitions such as the Blancpain GT Series, the Pirelli World Challenge, the
Blancpain GT Series in Asia or the International GT Challenge, a contest that good
insurance will incorporate in its next edition, the newly ‘acquired’ 10 Hours of

Within the different ‘Balance of Performance’ existing,
as it can be used in the GTE-Pro in the WEC, without a doubt, the
designed by SRO Motorsport Group is one of the most advanced, effective, and accurate

that there are. Thanks to this, this developer has gotten their categories
are reference in all the world, and that the class GT3-little by little every time
more relevant for riders, teams and manufacturers
. In fact, you can say that
ORS after 25 years organizing series of national, regional and global GT,
is the main authority in sports in the categories GT3 and GT4.

But what is so special about the ‘BoP’ ORS? why is your ‘Balance
of Performance’
get that GT3 is very different to have a
performance virtually identical? Those are the key questions and at the same time their
answers define the cornerstone of the system devised by ORS, as
recognizes St├ęphane Ratel, your founder: “The categories GT1 and GT2 already
we promoted had its place in that moment, as the championships
brand. The key was to bring all those cars, and allow different
models with different concepts of engineering to compete in a way
stable without provoking a war of development, which raises the price and discourages
the clientes


After ten years of experience since the premiere of the FIA GT3
European in 2006, SRO has managed to balance the performance of
many supercars
production designed under different
specifications and that use engines are very different. To be able to boast of
something like that, SRO Motorsport must evaluate each model or update, either in its
engine or drivetrain, on the chassis or on the aerodynamics, in similar conditions
to those of their rivals. For this reason, ‘Balance of Performance’ performed two
times a year at Paul Ricard
in a process in which each car is examined at the
detail and piloted by racing drivers, professional and independent.

The data collected form the basis of settings ‘Balance of Performance’ of each car, that can be altered from one circuit to another depending on their characteristics. In fact, this task does not end at Paul Ricard and Claude Surmont is in charge of overseeing this mammoth task both in the scheduled testing at the French track as well as in the various championships that SRO Motorsport managed during each season. Hundreds of thousands of data to analyze with the goal of having the manufacturers, teams and drivers happy with the balance drawn. An almost impossible task.


The four keys to ‘Balance of Performance’ are the
power, torque, weight, and aerodynamics
. The data of the approval
original car, the logs in the bank and the bank of tests
engines serve to give guidelines to a software simulation of an internal da
four figures by separate ‘BoP’ for each car. Over the years, the margins
have been adjusting to correct errors and to ensure that any car
roll within a margin of 0.3 seconds compared to its rivals
any circuit.

to Obtain all these parameters directly and not of the
manufacturers is also key to avoid falsehoods. Two drivers
independent are responsible to evaluate each car
under the same
parameters of tires, fuel mixture and adjustment of engine. The result
final is that more than fifteen manufacturers have put their GT3 in the hands of SRO
in order to make the correct calculations of the ‘BoP’. Up to 11 manufacturers
gave appointment in the Blancpain GT Series with an average of 15 cars rolling in
the same second in the six first appointments of the contest. And all for the
pilot continues to be the differential factor
