I must say i was really impressed with the quality of this part. It's on par or better than my Tekarbon. It came well packaged. Fitment to the hatch of my car was spot on, no need for bending or heating to get it fitted. The lines flow well with the car.
For an aftermarket part the fit is dead balls accurate. Virtually zero gaps with just doubled up painter's tape holding it down.
Shoot for FACTORY parts the fit and finish is excellent. My OE aero kit for the E46 323Ci coupe spoiler did not fit this nice. Neither did the factory aero side skirt.
Opened the box when I got home and test fit the spoiler. This is a well-executed piece. It fits great and looks great.
I've seen some bad CF out there -- this is NOT one of those.
Your quality is great and I look forward to more additions for the Z4M series. And now I can let others know that your customer service is as good as your products. It’s a pleasure to be a customer of yours. Thanks.
