Honestly, buy better brake pads, tires, and use the rest for track days/auto X.

But really, why would you want high flow fuel pump? You only need that if you are going FI.
If you want your butt dyno and the rest of the ricers to feel better just get the headers and tune.

Slotted rotors are a scam. Get better pads.
SS brake lines are just a fancy jacket over normal new brake lines.
K&N cone intake has marginal gains compared to a K&N drop in filter. You can just buy a one piece hose for $30 that's exactly the same result/look as the K&N kit.

Bushings and braces, makes it feel nice and tighter. Also more vibrations if you don't mind that. But minimal.

Just my two cents.
