I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
the only way to lessen this will be to switch to a smaller wheel and narrower tyre.
in reality this is an aggressive car with an aggressive suspension set up that tends to follow imperfections in the road. Most BMWs experience this to some extent.
I used to have a 3 series with 225 width, 18" wheels for the summer that did it TERRIBLY. In winter, I switched to 185 width, 16" wheels and it was much, much less of an issue.
Switching to smaller rims and narrower tyres will help but may not totally resolve it simply based on the design of the vehicle and its natural tendencies.
Sorry if you were hoping for a different answer, please don't shoot the messenger - I can only give the honest answer, which I have. Please remember that a low rating PUNISHES me for my honest and prompt response, and I receive nothing for my time and answer until a positive rating is clicked.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
