Hi all,
First post here, I've been a long time lurker though... I've drive a Toyota Sienna mini van(the parents) as a college car. I'm really sick of 20-24MPG and this car could really benefit from some aero mods. The car has a CD of .30 and I'm having trouble thinking up ways to improve on a steel box without heavy modification. The issue is my parents own it and though I do work as a mechanic and know what I'm doing it's not a good idea to mod other people's cars(especially your parents cars!
) so, what ever I do has to be 100% removable and or out of sight out of mind.
I've been thinking about a full belly pan and some grill blocks but that's all I can come up with and I'm not sure how much under body work will improve the CD as the under body is basically flat already. Got any ideas, musings, suggestions??
Here's the box:
Thanks,
Derrick
