Good Job Dee, There's only so much a Z can do with a 911/996/997,etc. because of the weight distribution. From a 60-70 mph roll,you'd prolly demolish him but those things hook up in the corners and off the line...the motor is sitting over the rear wheels...PLUS they don't have alot of drivetrain loss like our cars due to the halfshaft design....
The power does'nt have too far to travel to the rear wheels...they prolly only lose about 10-12% to the drivetrain.
