I have this set up on my RST. I LOVE the braking feel and I would argue stopping distance definitely improved (unfortunately I did not measure difference before and after). Had a rear dragging brake issue after install from dealer. After multiple back and forth visits it was finally resolved. I still somehow feel the weight of these things in my steering and even coasting. Mpg still not fully bacl to where it was before but its definitely way better than having a dragging rear brake. Wondering if maybe I dont have another issue going on. Still, it looks so damn good on the Truck!!!.
