Well, Bazeng, as soon as I have the means, I'll be attempting to make a lip and hood very similar to those. For the last few weeks I've been doing a ton of research on how to go about doing this.
For the hood, I'll probably use an evo 3 as a reference and fab up a hump out of steel to blend into a stock non-vented hood.
For the lip, I've been trying to figure out how to make it. Fiberglass is the easier solution, but I'd really like to make it out of urethane for durability's sake. The majority of urethane auto body parts are injection molded, but some are thermoformed. Both of which require quite a lot of tooling to accomplish.
That's still a while off though. If I do get around to doing it, I'll be sure to mention it somewhere on here.
