Just to follow up from this

REGLEMENT TECHNIQUE ACO - ACO TECHNICAL REGULATIONS 2006(-2009)
In order to maximise equality of performance and to maintain the current level of performance as well, the following adjustments must be carried out :

Aston Martin DB9 Coupe (ACO homologation N°: LMGT1-01) :
- Addition of 25 Kg to their minimum weight ;

Corvette C6/ZO6 (ACO homologation N°: LMGT1-02) :
- Addition of 25 Kg to their minimum weight ;

- 1st level of performance: LM P1
- 2nd level of performance: LM P2
- 3rd level of performance: LM GT1
- 4th level of performance: LM GT2

---
LM GT1: Given that the performance and top speed of these cars are constantly increasing approaching those of the LM P2s, their air restrictors will be reduced by 5%. As the capacity of the fuel tanks has to be adjusted according to the type of energy used (petrol or ethanol; see 'fuels' below), the amount of fuel on board the car must not exceed 90 litres (-10).
LM GT2: To maintain a reasonable gap to the GT1s the air restrictors will also be reduced by 5%. As the capacity of the fuel tanks has to be adjusted according to the type of energy used (petrol or ethanol; see 'fuels' below), the amount of fuel on board the car must not exceed 90 litres (-10).

- A 25mm Gurney flap minimum in LM GT1, and 15mm minimum in LM GT2 will be obligatory.
- The air restrictors will be reduced by 2% in LM GT1 and 5% in LM GT2.
