I just got my car running w/ stock mani's and Sport 700's w/ .64 housings. This car feels amazing. Even w/ stock mani's, the lag is not bad at all. I would highly recommend them. If you are getting mani's, I would still recommend the .64 housings unless you are just going for huge dyno numbers. If you do the .64's w/ the mani's, you will have a very nice spool and a very large usable powerband.
