Building ground effects

[AndrewBird]

I know that RyanG's splitters work really well. I remember Jordan talking about it pulling his front end down 1/4" at 80mph or something like that. He was running a Reiger lip with a RyanG splitter if I remember corectly.

Yes, Jordan's car was pulled down quite a bit when I saw it moving. A lot more then you would think a little piece of plastic could do.

Josh,

Where are you finding ABS sheet like that locally? I was going to start looking for some for a project.

Maybe the links are mis-directing...but besides some downforce/speed numbers, i don't see much on those two prototypes. That nissan is badass though...the one from Gran Turismo, even though it doesn't show pictures of it on that site.

the links are fine, look at the lift (downforce) to drag ratios. most downforce with the least drag = ftw

Tear Drop? Not Quite!

Look at the way an M3 is different than an E30 for ideas. The high deck lid, front air dam, and side skirts. Open wheel cars are rocket science but sedans are pretty straightforward. In the following picture, note the aerodynamic innovation reflected in the side skirts - or is it for turning in driveways?

considering that sideskirt design was abandoned by bmw and hasnt resurfaced in any performance car since (not counting ricers), id say it was for driveways.
