I just purchased a Series VI 2 weeks ago and the Team Disount does apply if you go through Saleen - I got a better price though through Haney Motorsports though you may want to givbe them a call
Saleen uses a whipple on there kits. The reason that oil leaks out of the front when they are tiped forward is because there is a vent hole in the bolt that holds the hub on the drive. The compressor only hold about 6-8 ounces of oil so the oil level for the compressor should probably be checked.
