all true, but the weight is very small compared to the 4,000lb vehicle especially considering that you add 150-200lbs with a driver, another 150-200lbs with a passenger, probably 100-150 lbs with a full tank of gas

as far as the driveline drag, it is there, but the vx doesnt have any more drag than my civic, i cant imagine it getting much better
