QUestion about GTS rules

[sbrm]

Interpretation question

Does article 16.3.1 which defines modifications mean that engine and gearbox mounting other than factory stock is not when allowed when the factory stock chassis is made from carbon fibre?

16.3.1 says:

"...Carbon Chassis: the chassis homolgated for the road must not undergo modifications. The mounting points for various mechanical elements fixed on the carbon parts of the chassis(engine, gear-box, suspension,steering etc., must be those used on the road car. No reinforcement will be permitted apart from those necessary for the installation of fuel equipment or rollover structure in the cockpit..."

While a GTS car must not use its engine as a stressed member it would seem quite common practice to use engine mounting to strengthen chassis stiffness. This doesn't seem to be permitted with a carbon chassis. Interesting if you wanted to convert an Ferrari ENZO to GTS you might be able to additional brace the engine and gearbox to the metal subframe, but not to any of the carbon part of the chassis.

It wouldn't affect the Corvette and the Saleen as they are not primarily carbon chassis!

Any thoughts
