Anybody seen Mike Oxlong?

Sorry....subject title has absolutely NOTHING to do w/ my question (but I wanted some answers/opinions - needed an attention grabber ) I'm going w/ stud mounted 1.6 rr's for my next mod. While we're in there, anything else that we should bother upgrading and why? Pistons? Rods? Thanks for your input!
