The easiest way to put it is this: the only way not to break traction is to roll into the throttle. Any speed, any gear (below 6th). You floor it, you spin the tires, even when warm. And I am on R888Rs! The acceleration is utterly brutal. What’s more, the lofty redline makes chasing that 8500 RPM an exercise in bravery. Speed comes SO fast, and torque peaks SO low. I had trouble finding straight sections of road which allowed more than one up shift before I needed to brake. Its fantastic that this kit did not compromise the original character of the car, but just amplified it to an insane level... up to 11, if you will.
I firmly believe that any more HP would make zero difference and be lost on me as the car is presently traction, road condition, and (in my case) driver limited.
