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?
