Thanks Boostin. One thing I learned (after reading way more than I should have had to) is that for most of the ~250-350awhp daily driven crowd, a pair of well-made cast pistons with stock-like clearance would be an ideal solution. But all we've got is 6 different types of forged pistons, or stock. I think it was GTTuner who recently posted a pair of forged pistons with massive depth to the ringlands. Would that be possible with a cast solution?

And, secondly, are the stock pistons really that much of a problem or is it simply that the stock tune is very questionable & alot of tunes also have dangerous running conditions, leading to the illusion that the stock pistons are weak for both stock and tuned cars. Get me?
