Good advice for people that have not done it before.
I have done all my mods. Paint, fabrication of custom aluminum parts, suspension, polished the exhaust, leather interior, made my own LED lights, custom HID, and stereo install.
I'm work in manufacturing; ABS is garbage for this application.
Mugen and spoon have used wood splitters. Good enough for me too. I already have sheets of marine grade multiply. I'm going to water proof it and glaze the edges, its' not going to look like wood.
If you are comfortable with fabrication, its not a "hard" project. Some members have self built turbo kits. I'm building a "surfboard" in comparison. It has no moving parts. Lol
