A buddy had ordered a set of pistons and hadn't heard back from them. Was concerned that they might be a smoke and mirrors internet operation. After further research, we figured they are racers, and were probably racing instead of answering emails every minute of the day.Good to hear positive things about their reputation, Their price on these particular pistons whips the pants off of everyone else selling them.Still don't know if I should try to put the boost on that much compression with pump(93)premium though.
