Subframes?
Whenever the chassis kinda wants to twist when launching it is absorbing some power. Therefore you lose a lit bit through the chassis. SFCs will lessen that effect. Mostly though you will notice more in handling. It is a very good mod to do.
My car reacted very well to subframes and STB, the only noise it has is a little driveline noise after intalling the aftermarket shifter.
