Lightweight Underdrive Pulleys?

[Stuka]

Guys, you've all seen my 535i, and as of now i just got paid, and i have about 300 bux to spend, and i want to buy new underdrive pulleys, as performance wise I cant think of anything else i can slap on besides a new MAF, cams, or forced induction. im running out of ideas and this money is buring a hole in my pocket. Does anyone know where I can lightweight underdrive pulleys for my 90' 535, or have any ideas how i can spend this money to make more vroom vroom?

ahh, of course they dont... I think i picked the WORST tuner engine on the market. I just went to dinan, and i started to cry when i saw how much they wanted for their headers. 800,000 dollars. or 1,000. cant remember which. Stupid dinan. I wish i had my old 325... sigh

oh and if i buy lowering springs from bavauto, do i have to get new shocks as well? my car has 130k miles and the stock shocks, so what do you think? If all of these ideas suck, im just gonna buy that cool gtech performance meter...
