My 05 G6 GT has these same rims, On the inside they say Enkei USA. I am assuming that these were bought from Enkei by Pontiac, not by the original owner.

Why do you want something that is lighter than stock? I know the less weight of a spinning mass equals more HP. But... wheels are not an area you want to skimp on rigidity. The last thing you want is and inferior wheel that is lighter weight but will kill you. LOL.

You might be right if lighter=weaker or less rigid. Depending on design and materials, lightweight wheels can be stronger and more rigid than heavier ones.

Lighter wheels are not inferior to heavier ones, just more expensive.


Also, this is not a new concept. Muscle cars often wore "mag" wheels. these were made from a mixture of aluminum and magnesium and would more accurately be called "alloy" wheels. Then as now the concept was lighter weight without sacrificing strength. (True "mag" wheels are sometimes used on high end sports cars but can be quite dangerous if they catch on fire because magnesium is flammable.)...

Cause the part behind that looks to be aluminum to me...
