what to install first or not

[johna]

I purchased my used boss LS about 1 month ago. Unfortunately none of the extra LS parts came with the car except the red track key. I have autocrossed the car and plan on going to the track next weekend. Since I need to buy the splitter, brake cooling ducts and transmission cooler - which one if any is necessary for the car for the track? I was thinking the cooling ducts as necessary....
How necessary is the splitter? or transmission cooler?

Brake cooling ducts and add your favorite DOT 4 fluid while you're at it. The trans scoop is inexpensive and easy to install. Skip the splitter unless you're going to track your Boss a lot and not drive it on the street much.

Yep, DOT 4 brake fluid, brake cooling ducts, tranny cooler.

ATE Super Blue and Y2000 brake fluid (same stuff, blue and amber colors) is a great, and inexpensive fluid that many here use. I have not tracked with anything else, and don't see a need to look for anything else.

Once you're hooked on tracking this beast, you'll want camber plates (MMC or Vorshlag), racing wheel studs, and a few more things, but your first 3 will get you going.
Enjoy!
