I wasn't uncertain about the weight difference between d-b-k series as i am about the power outputs, gearing, braking, and steering. Example: you do 6 laps in a d16y4 ek hatch, then you get into an ek hatch with fully built B or mild K series and try to drive the car exactly the same.

Jason, i think you're correct to the extent that it would mostly depend on the drivers capablity and experience. however i do believe that there would be some differences in which even a well skilled driver couldnt completely absorb.
