Default Great information, but misleading...

Here we go...

US spec STI pistons are made of stonger material than forged according to Subaru. Is this PR stuff or fact?

"This latest STi piston is a departure from previous years in that it is a cast aluminum design. However, we believe this to be a special hypereutectic material and STi claims a 120% increase in strength over their previous forged pistons. "
