you'll have a great time on the track in the Boss! My first year of running I didn't really put any mods on, just ran it stock to get the feel for the track & the Boss. you've done the easiest mods: dot4 fluid & pads. I would definitely get tires/wheels next. I installed the Ford Racing Boss lowering kit too & went with 18x9's & 18x10's with Nitto NT01's all the way around. Great tire, sticks like glue. I also installed new stainless brake lines front & rear this year, adjustable rear lower control arms, & I'm in the middle of adding the Cobra Jet intake/throttle body/cold air intake too. Track Night in America is a pretty good time for the price, I definitely enjoy it.
