I have purchased a used set of ZLE brakes and also the DSSV to install with my build. (I'm doing things in deliberate process to see what actually helps and what doesn't)

I bought these before I had a chance to haul ass in the car and quite honestly, the stock stuff is more capable than I even thought. I will add the brakes and DSSV at some point, but not before I add grip and different pads to try.
