I have my 2004 GTO. I have it gutted on the interior side. Exterior I have 18x10s wheels in rear and 18x9 in the front. Custom rear spoiler along with custom rear diffuser. Engine wise I have a ls1 fully built. It’s been bored out to 382 forged crank and pistons. Texas speed stage 2.5 243 heads with a custom cam. I still have the stock ls6 intake and throttle body.
Mods coming up will be front and back coilovers, swaybars, new bushings, oil cooler, power steering cooler, mishimoto radiator, e85 conversion and wide body conversion. I have the parts but need the time to install. So stay tune should come out pretty sweet.
