I wasn't hard on those wheels when you first showed them but with the cab on they look so much better. I'm excited to see what they look like with fenders and a bed. Bummer about the towers but really excited to see progress.
Do you have a flex joint in the exhaust anywhere? Just thinkin to my self I think it would constantly blow out collector gaskets with the engine being able to move and the exhaust hard mounted.
Some dude with a new edge mustang popped up on stanceworks with the DTF. It was pure chance. I've never seen them mounted on anything else. even their website is mostly photochops.
as long as you're looking at cheap wheels. look into phatfux.com, please ignore the name, they make a wheel called DTF that I almost bought in 15" for my 510. I love 4 spoke wheels.
I ran 13" libres with 280zx brakes. couldn't use stick on weights and I had to shave the caliper a smidgen but it worked fine.
Edit, wait are s30 brakes bigger than s130 brakes?
