Factory Wheel Weight - S8 21"

[Chris Morales]

At the tire shop, I weighed my bare factory 21" wheel off my 2013 S8. 35lbs and change with no tire. Surprisingly heavy. I could see a rolling mass weight savings of perhaps 50 lbs with a swap of all 4. But I recall a magazine test that showed quarter times and traps were not substantially affected by lighter wheels.

Just thought this was interesting.

Ride will improve substantially as will steering response with a lighter wheel, all else being equal

I have a set of Hypersilver Rotors 21" that I was thinking about selling.

If you want lightweight I have one of the lightest 21" wheels on the market that I'm selling. 21x9.5 at 25lbs each, Forgelines. Pm me if you want pics.

this is one of the reasons that I went with 20s, as well as the taller profile tire, because the 21s are too much for NY roads.

If I am not mistaken, my 20x10.5 HRE FF15s were 26lbs each. Very good weight savings, even with the heavier tire. Everything is better with less rotational mass.
