Those of you that have received your shocks, can you tell me what series they actually are? Are they Factory, Performance, or Evolution series shocks? I'm looking at the Fox literature just to better understand what I'd be buying and I'm confused. GoWesty lists them as Factory but Factory only has external reservoir and it appears the ones that GoWesty are selling for the rear do not have external reservoir. Also, the list price of the Factory series is significantly more than GoWesty is selling them for.... My bet is that they are Performance series, which would be fine, I'd just like confirmation. Thanks!
