I have customer of mine with a G8 on order and is going to be installing one of these kits. It looks like a quality piece. I know IPS has experience with these kits. I hope to get the opportunity to see one of these kits in person. I know I need another twin turbo car like a bullet in the head. But it sure would be nice to have another 500 rwhp car that weighs 300 pounds less then the mustang. Worse case scenrio I wait to see how the G8 turns out. Anymore thoughts or opinions on these kits? If you were not going to get APS, what would you go with?
