If you are speaking about the 15" B14 SE-R wheels, which I have and highly recommend, they can be lighter than some aftermarket wheels (i.e. heavy chrome "bling bling" 18s). Also, I feel they look great on a B13 Classic. Aftermarket wheels can look and perform very well (if they are lightweight and fit the car). It's personal preference. Someone recently here on the BB stated that the B14 SE-R wheels weight 17lbs --- if so, I think that is a decent weight for a 15" wheel... yes there are a lot of 15" wheels lighter than that, but for an OEM wheel it's pretty damn good. Hope this helps.
LOL, you're like the eighth person that's asked me that this week. It's hella easy, just follow the instructions in the December '00 issue of SOLM - it's for the B12, but the idea basically carries over to the B13. Take your time with them and they'll come out great.
I have a b14 still with the stock rims. The thing is, even when I get new rims (hopefully next spring) I'll probably still keep my stockers for my winter tires. Looks like none of you will be getting your hands on MY rims... =)
i've got the b14 ser wheels, and damn. everyone i know has complimented me on them, they look bad ass. i got mine for 300! btw, the handling difference with performance tires/bigger, lighter wheels is tremendous! plus, the centercaps say nissan, peole usually don't look twice!
