It was in the Production class.
It was standard except for:
- Carbon bonnet, carbon boot lid
- Carbon mirrors
- Wheels and tires
- Suspension
- Roll cage, race seat, harness, fire extinguisher
- Onboard jacks
- Bigger oil cooler
- Ducting cut into front bar
- Exhaust tips
- Lexan rear quarter windows
- Racing fuel cell
What was stock was:
- Engine
- The body (minus the bonnet and boot) including no extra welding
- Drivetrain
- Brakes
- Much of the exhaust
- Most of the windows
I'm probably forgetting some things but yeah. To finish the race is a good result in proving the reliability and durability of the GT-R as a production car.
