I personally think the S14 rims look good on the car. I wouldn't mind having a set of those on my GSX or a set of FD RX-7 rims.

You still having trouble tightening your alternator belt? It's the same as the 1st gen Neons (98-99). There's a 15mm bolt that goes to the bracket on the block, then a 13mm on the back of the black top cover and another 15mm on the side I believe. Loosen them all up, then crank down on the back 13mm bolt. That'll tighten it all up, get it where you need it to be and then tighten the other two bolts.

Clean looking car man, keep building it!
