In general, OEM's do all kinds of things for mileage, emissions & cost concerns - and just because Brand-A puts one part in their car, doesn't mean Brand-B can or will put the same kind of part in their car, even if they are direct competitors. It might only cost $100 more per car to put forged pistons in vs. cast, but when you multiply that out over the entire run of cars for a year it adds up to a shiteload of money - which means the company is expending a large amount of money to please a relatively few car guys who need the extra strength. Those kind of expenditures are the first to go when the corporate beancounters start looking for places to cut costs.

As an unrelated example, my car came from the factory with a whopping 215bhp serving of weaksauce, even though Camaros of the previous years came with 275bhp. The Mustang still sold well despite the difference, so Ford obviously saw no reason to change what was "working".

I agree but with a car like the STi which is sold to a limited market they could have gone a step further with the design to help hold better power on the after market aplications. Thats all
