Looks beasty man! Did you consider building a splitter to extend further back that the bumper? That's what I'm planning at the moment, but dunno if it's viable given clearances etc?
Yeah I've started cutting the arch trims in preparation! Just need to get some sort of chemical to clean up the insides before applying stone chip and rolling them up!
Good effort man, liking this project! NA's definitely have some potential with a bit of money spent on the handling! GT/V carriers and discs are a great upgrade!
