For those willing to got a bit further you can get 15x8, roll formed, 6UL, 11.4 lbs, $159 each, just have to do the 4x100 conversion, 4 lbs per corner is a big deal in weight reduction in the most critical area of a vehicle
I have a set on the way for my AS tires, for my street tires and my race tires I run 15x9, 13.4 lb roll formed wheels, bought ten of them for $1240 shipped! (note, they will not fit a stock bodied FiST unless you change the rear camber and roll all the fenders)
The TD is a good solid wheel and you are still saving a ton of weight over the stock wheels and will love how much better the car rides so not a bad way to go at all, I just tend to go a bit more over the edge, been a life long curse, disease, blessing perhaps.....
