I will chime in with my "OPINION". Assuming the car is BONE STOCK. Assuming this is not your first rodeo with a sports car, there are a few easy quick things you can and will want to do. Oh wait........> let's Assume this IS your first rodeo with a car that has this much torque, get the tires and learn the temperament of the car. NOTE: There is no PC or nanny aids that will save your **** in this car! It's all on the drivers input or lack of. It's amazing how many THINK they can drive when coming from a Vette, Porsche, stang or other until they jump into the snake. They soon realize how the traction controls and other things helped them. Typical initial response is.. "Oh.. I have had cars with more HP, faster, etc"...Yeah..OK. Trust me... It's different and sneaks up on you. It's not the fastest car but it's just DIFFERENT. So take the time to learn the car in it's initial state then start the "upgrades" and or improvements.
...in addition to what you already stated:
Smooth tubes
Air filter
Power steering fluid reservoir vent and DO NOT OVER FILL
High Flow cats (Reduce that cabin, side seal heat)
Change ALL Fluids
SS brake lines and pads.
Before you get the new tires, go into an open parking lot and have some fun! Smoke it up a bit. You will see how easy it is to get sideways in this car.
ENJOY IT!
