For what it's worth, I have bought parts and wheels directly from them several times. Just 2 weeks ago they shipped me a center for mockup and fitment (free of charge) to confirm a backspacing change.
While I agree they are TERRIBLE at responding in a timely manner, they have never not-responded....and when I do send money for parts, they are on the ball to get it shipped out to me ASAP.
Will I continue to do business with them? Probably not as I just had a flawless experience with Forgeline, but I feel like if you really want to get your hands on some of their wheels, just email them or call and leave a message.
Just a heads up, the person who takes the orders is out till the 11th on vacation.
