Design and material selection all looks good. Have you thought about where your coil over shocks will need to mount and if the frame will need to notched for them. Unless the frame is narrow enough than it won't be any problem for you. I only ask cause I saw this at the mounds on Sunday. I wish I had took a picture of just the coilovers where they passed the frame but he had to notch the frame around 2" deep and 6" long to place them where he did. It looked real good and boxed in very well.
