Plastic spacers are just spacers .. you might find aluminum ones as after market parts ,
if the good enough for most every one else fails to meet your personal standards..
The steel in the Cogs in cassettes are all the same.. only the finish plating changes,
higher end uses lighter metals, Ti & Al . the race day is all the durability required then.
but 7 speed is 90's you use what you can get.
