I've worked with ECS over the last 8 years from my VW days till now. And to be honest, they are great for sourcing oem parts but that's pretty much it. All their in-house products & kits aren't that great, ie their oil drain plug among others. Stick to oe or reputable brands like Stoptech, Brembo, etc.
