Need help ID'ing these wheels
 

Been gone a while, ended up buying a B5 winter beater with these wheels. 1 is an OEM ultrasport 18" rim, the other 3 are aftermarket...something. Previous owner said he bent one and used a spare.

They are drilled for 2 bolt patterns, 18", have audi center caps. Look like they may have been a slight gunmetal finish at one point.

Does anyone know what brand or model these may have been? I'd really like to find a matching one. They are not replica ultrasport/rs6 wheels as you can see the slight differences. Thanks
