Looks like a good start. A 3" suspension drop may be more for looks than for aerodynamics. You would probably get more bang for the buck by doing a full belly pan at stock ride height. These cars are already pretty low and broken oil pans are not uncommon on lowered cars.

I have a feeling you could be right. Perhaps 2" would be more prudent? I have a skid plate on already - it's a standard part as far as I can make out. The replacent suspension I've already bought is fully adjustable coil-overs so I can adjust ride height as necessary. The main point is getting air to go anywhere but underneath.

That just makes me want one even more.
6 more months of saving and I should be able to get one.

Look at weatherspotter and his brother's rides to see how good wagons look eccomodded.

Thanks Jason, how do I look at Weather Spotter's brothers' car?
Good luck getting your own. I didn't like it much when I first got it but I love it now.

I have the aero trix (heavily modded 2006 matrix). My bother (soulster) has a mostly stock Kia soul and does not like the look of my car .

I will read through the thread and add my thoughts, I just wanted to clear up who has the car modding experience

I like your car choice, wagons are nice mix between people and cargo and MPG

Mod tips (links are to our wiki mod page for that mod):
1. grill block is a cheep easy first mod. Grill block partial or full - EcoModder

2. smooth wheel covers Smooth wheel covers - EcoModder

3. belly pan Belly pan - EcoModder

4. Rear wheel skirts. Rear wheel skirts - EcoModder

5. side mirror delete. Side mirrors - EcoModder

6. Tire pressure to max sidewall. Increase tire pressure to max sidewall - EcoModder

7. Scangauge ScanGauge OBD-II computer - EcoModder

The first 7 are relatively cheep and easy to do. 8- 10 are harder but sill very doable.

8. Kill switch. Engine kill switch - EcoModder

9. Kammback. Partial Kammback - EcoModder

10. roof rack removal. Roof rack - EcoModder

11 Full boat tail. Full boat tail - EcoModder
this one is harder and will take some $$$ and time commitment. I just did it and it took me a strait week of work and about $300.


Issues with lowering:
1. will prematurely wear out your half shafts. I have a brother who tests them at work, keep the angle the same. Any change will kill them 2-3x faster.

2. reduces ability to go over debris in road

3. reduces ability to drive through snow (might or might not be an issue for you, I need 6-8" in the winter)

before lowering a car I would make a air dam to the same height and see if that scrapes or if it helps. It is also a cheaper way to get the same gain. Front air dam - EcoModder

Is the car a gas or not?
Manual or not?

I hope this gives you some food for thought. I would also look through the other mods on our wiki, it will give you plenty to think about

Thanks WS, I've got a few mods lined up but I'm waiting on the delivery of my ScanGuageII. Without that I don't know what I'm improving on.

I quite like the look of your car - persuading my girlfriend to get in something like that s a different matter entirely!

I have a post in the Introductions section that lists all my planned mods but I've also been wondering about hydrogen injection. Any thoughts?

Hydrogen injectors are placebos really, takes more current from the alt than produces extra power/FE to compensate
