2013 Subaru Impreza WRX STI - Project Log

[jedi_sol]

Pictures as promised!
The edges still don’t sit as flush as I’d like. Maybe the fiberglass/resin warps over time as I keep sanding? I tried putting a heat gun on the edges and clamping it down. Then as it cools, it sits more flush again. But for some reason, over time, the edges start flaring up again. That’s why I decided to move the mounting holes to even farther to the edges. However, im very pleased on how smooth the “face” came out.





I’m thinking of Plastidipping the Ecomodder logo in the middle 

Looking good! If it were me, I'd have the STi and the Stars showing through- but it looks good.

That'd be too cool. I love it.

Building front lip
The lip only extends down to the same height as the OEM front tire spa (which is the lowest part of the under body)





Not sure if I should leave the middle open so that the air is channeled down the middle of my under belly tray? Or should I extend the lip all the way across, creating a small air dam?

Totally not an expert, but I think conventional wisdom would say to extend the lip all the way across.

Also, since you've made the underbody of your STI much flater than it was before, have you considered fabricating some rear diffusers? Maybe like this: DIY Rear Diffuser : The Writeup - NASIOC ?

Thanks for showing me that write up! Yes, diffusers is ultimately in my planned mods, however, i never started making them yet because i think i read that they actually create downforce, which is bad for fuel economy.

None of the "extreme" eco cars on here or from car manufacturer concept drawings utilize rear diffusers. I am still doing more research.

I've decided to move forward with building a rear diffuser

Wow, nice find! That's something I'd like to try for my Cruze as well. I really have no experience with this kind of stuff, still in the reading and planning stage for the majority of it (especially since it doesn't appear most people have done anything to a Cruze). I wonder how he was able to curve the aluminum frame he built for that diffuser.

Also, if you had a diffuser in the rear, might that affect the decision to extend the front lip or not?

All the way across. The car on the left below has the factory JDM STi front lip; it fills in the center gap. I can confirm this because I have one on my car.

I really look forward to your build. That other one looks fantastic, but there isn't much of a build for it. I appreciate your dedication to tracking your progress.
