Al, they're Rota Grids and yes they're available locally.. there is a vendor on Rexnet that sells them.

That being said, I've heard they're cheaper through wheeldude.com. $950.00 USD per set in 18x9.5, plus shipping.. and I'm told it still ends up cheaper.

I can get Rota's through Otomoto too but we're limited in what sizes are available for Subaru's because they mainly bring in the Nissan offsets and sizes.
