That HPD Supercharger really caught my eye. I know it isn't something I'd ever be able to afford anytime soon, but I was wondering about it. Anyone who has or had one was it worth it? Also did you find yourself needing any other upgrades? I saw there was an exhaust upgrade, some body kit stuff and a limited slip diff. Are those things you'd eventually have to get? The 18 inch wheels sound appealing, but I love the stock rims on the 16's I've got right now. Just some thoughts!
