I am thinking of using the stock 16" alloys from my 2014 Mazda3 GS for winter. This means I will need to buy new rims next year, and I am thinking of going up to 17" as there is more selection of performance tires. I want to keep the weight down as I believe the stock 16" rims are around 19lbs. Does anyone have any suggestions for rims that will be around the 16" weight? I like the style of the Volk TE37, and the 2008 Mazda MX-5 rims (the dealer wants $575 per rim), I don't want to drop that much money on rims though.

I have the opportunity to buy stock 2010 Mazda3 GT rims from a coworker, I believe he wants around $400. These are around 21lbs per rims though. Would I notice any difference or should I look for something lighter?
