Now that the GTM has had several years of shakedown and several teams have taken serious racing with this chassis, what is the consensus for the upper limits for speed for this car? What seems to be the obvious limitations and/or remedies to reach the next level? Has the chassis and drivetrain proven to be up to hard core racing for an entire season or are major modifications required to keep it together and competitive? Have there been any surprises along the way of developing the race chassis and drivetrain?

Just some random curious thoughts. I'm starting to wonder how the 818R is developing in this area also and what others have found but that is another forum....
