I am going to go back and say, keep it simple.

Adjustable koni's all around and learn to Drove. FWIW, i recall beating the young novice (OP) at AX in my Bone Stock (suspension, street tires) 944 by several seconds. That's an eternity on a 45-60 second course.

Spend the money on the seat time. Then some more seat time.

The more seat time you have, the more you will undestand what improvements you want to do next.

Maybe you will decide you want something quicker (S2/Turbo/Boxster/911) anyway.
