Got the rear rps kit from ECS the rears are not vented and look thin.
Should I use?

The invoice states it is the rear kit but the brembo rotors are so much thinner than my oem's and the one they sent are non vented.

The front RPS kit is fine

ES# for the rear rps kit 1306740
ES# for front rps kit 1306686

Did any x5's come with solid rears from the factory?
If so I guess they can call them oem's but when I look on their site all I see is vented rears which made me think that is what I was getting.

I did google the rotor sku and it comes back as a solid for an X5...so bummed.
My friend and I worked on the car all day and this was the last part.
