I bought your cars clone a bit over a year ago for my new daily, so I could start leaving my RSTI in the garage. Not gonna lie, your build was one of the first ones I found after I bought my DD 05 OBXT. I knew I wanted to lower and get new wheels but the info on your build helps guide my parts decisions. The car looks great, keep it up.
Though I opted against coilovers and did Koni yellows in LGT housings with Swift springs, Whiteline rear links to help dial it in. Wheel and tire sizing selection is my current project. I found out the hard way that 235/50/17 tires on 17x8 +48 wheels do not fit the suspension I installed.
Do you have any issues with rub running thse 18x8.75 +20 and 235/40/18 tires? I imagine you have a 2+ degrees of camber per wheel plus rolled fenders.
