I'm in the market to buy some aftermarket wheels for my '00 2.5 RS sedan. I would like to keep the cost down, yet at the same time I would like to at least purchase wheels that are lighter than the stock ones. I've read that the stock wheels are 16x7 and are 16.5lbs each. What are some popular aftermarket wheels that are plus 1 sized (17x7) and are LIGHTER than the stock RS wheels. Any help would be appreciated! Thanks.
