I jumped into the GR1 race yesterday morning just to see... Started making time and ended up winning at the end with the Porsche 919 pretty easily on RM not conserving fuel at all and just stopping when needed. Short shifted at the end and since I started with zero strategy I had to bump and bruise a little to get through. I think a crb is totally possible with this car and probably easy with RS tires because the fuel dictates the pit, not the tires in this format. The Porsche always feels like a cheat code at this level. Such a planted and predictable machine.
