which is why I didn't claim it was faster.

Antihero

lol @ calling 13.6 pounds significant on a 3600+ pound car.

Antihero

ok, so lets extend that theory.

Already taken into account.

Antihero
10:37:27 10/17/12
So how about the inertia of the suspension?

You are failing to understand physics.

TriniTT
12:18:47 10/17/12
accelerating 3600 pounds forward is what your engine's doing

TriniTT

There's really two separate things going on here.
