Okay, so it looks like I'll be doing a piece by piece swap instead of a whole shell swap... there are a few pull-it-yourself junkyards within 5 miles of me, and I know that at least one of them has a bunch of metros so I won't be at a loss for parts anyway.
I've seen people list things like hyper-inflating tires and advancing their timing in order to improve FE... what are the downsides to doing these, and what does it really involve? I'm assuming shorter tire life for the overinflating, and perhaps risk of engine damage or more carbon buildup from the timing but again that's just an assumption.
I'm trying to get a better understanding of aeromodding. I'm a bit confused when it comes to "vortexes" being created in the rear of the vehicle... I'm thinking that's where the wind "curls" around the back of the car, and that the "boat butt" mods smooth that out. Is that right?
