Most alum. rims that would fit your ride would be 14" and just as heavy
as the factory 13" rollers,if that's what you're running,and not really lighter
if your on 14'ers now.Maybe heavier depending on the rim.Plus you'll not
realize any change losing rolling mass unless it is dramatically better.

The OE seats are ridiculously heavy,mounting lite man. late model buckets
would save you30-40lbs easy.
