BMW M4 Ceramic Brake / Wheel Damage - Final Update

I decided to write to the Managing Director of BMW UK, Graeme Grieve, explaining all of the problems I have had with my BMW M4’s carbon ceramic (CCB) brakes and wheels. I asked for a set of the new 20” wheels that would offer an additional 1¼cm clearance from the wheel to the caliper.

In the mean time I also contacted my local BMW dealer and told them that I was not happy. Interestingly I was advised by the Sales Manager that he was aware of my issues and more importantly, of the other 3 cars he had sold with the Carbon Ceramic Brake Option all had had the same issues with wheels and brake calipers being replaced.

A couple of weeks later I got a response from BMW UK. They were prepared to supply a set of 20” alloy wheels, but I would have to provide the tyres. Unfortunately, I was not prepared to cover the tyre cost and was getting no further. To add to this, the 20” wheels are only available in a silver finish, and I wanted black to match the existing 19” wheels.

After a long and painful decision, I decided to sell my beloved BMW M4 Convertible. Even so I had purchased my car from my local dealer and they knew of the problems I had encountered they offered the lowest figure. In the end I sold the car to a BMW dealer and have made a significant loss. I wrote to BMW UK telling them that I had sold the car after receiving the very poor customer service. I have never had a response.

The bottom line for anyone who has similar problems is, if you fight directly with BMW UK you can obtain a set of 20” wheels, but expect to buy new tyres.

I've experienced similar problems with the caramic brakes on my M4. The wheel is damaged and my dealer will not replace it. Can you offer any advice?

I'm sorry to hear about your problems. It is clear that the gap between the wheel and caliper is not sufficient. My advice would be to contact BMW head office in your own country and ask them to sort it out.
