Not critical unless you get really fast, and go a lot.
For starters, its better install some brake ducts, Brakeman 3s, Dot4 brake fluid, you already got the ACR oil filter adapter, need windage tray, trap doors, 20-50 Mobil 1, Water Wetter, RedLine p.s. fluid, tighten your p.s. resevoir cap every session, 5or6 points, later you might want to get a more agressive alignment, lowering a bit, Accusump, Hoosiers, big brakes, diff cooler, Penske tripples, roll bar, big radiator, well the list goes on and on!
