I'll keep the VGs in kind for use on my Saturn, maybe(it has a OEM wing)...

But after hearing some opinions, I think that a partial Kamm would be best for the roof, and maybe a lip spoiler on the trunk lid, if I can make a decent one...

I wish I hadn't thrown away the three OEM hubcaps that come with the car, given the easy ways to make smoothies out of them...

I also understand that the 07-up L61 Ecotec has HPTuners support, which opens me up to tune the powertrain for better mileage and power...
