Don't think I‘ve ever bought anything from them, but at least right now they ARE a registered vendor… business practices a side.
On the flipside, most members here are NOT hard use cases and should have an idea of what they are getting into. When I did have a business I spend more time talking folks OUT of the latest greatest “race” parts and many into OE which they would be happier with in the end. Back then margins were better on the race parts but happy customer return business… well, repeat business.
However, some people HAVE to buy parts like these to fit the other aftermarket parts they have. IE Alcon brake kits and other cases.
No reason to pretend to be a customer is my point.
