Some people who care about car performance would gladly pay twice the price to get that 4% increase.

It's not only HP necessarily either. Lighter pistons could also improve responsiveness. You're accelerating less mass so that could mean a nicer torque curve if you increase weight savings in the moving parts of the drivetrain.

Yeah, 30hp is a lot, esp considering the weight is reduced.
