I have a question-- how much do the stock rims weigh, and do they weigh less than the mazdaspeeed aluminum/magnesium rims?

 

Stock rims weigh 21 or 23 lbs.

 

Stock wheel weighs 21.5, but I've heard anywhere from 22-24 as well.

The Aluminum MS01 Wheels are 7.7KG for gold and 8KG for gunmetal (don't know why they aren't the same) or about 17 pounds for gold, 17.6 for gunmetal.

The magnesium MS01MAG are 7.3KG so about 16 pounds.

These numbers are directly from Mazda USA's website except the stock weight of 21.5 which is from this thread:

EDIT: And just in case you are wondering, they are all 18*8 +50 which is the stock size/offset.

 

thanks man. these numbers are interesting-

I knew magnesium rims were expensive- but jesus!

 

gotta pay to play. magnesium is pimp
