Challenger SRT Hellcat
If you drive a RWD vehicle, or plan on getting a HC, I highly recommend DirtFish's RWD course. I just finished the 3 day course. WOW! Super fun and highly useful for anyone who drives. You drive Subaru BRZ's. Yes they are Subaru's, but damn they are fun and inexpensive. You get to drive on both pavement and gravel. Ive been to a few racing schools and this was by far the best so far. I plan on attending their advanced course as soon as possible.
