Mushrooming refers to shock tower failure due to an impact with the strut. Because the strut regulates your Mini’s alignment, mushrooming can make it dangerous to drive and result in serious damage to your vehicle.

Common Causes of Mushrooming

Your Mini’s iconic low profile to the ground may make it more vulnerable to shock tower damage, such as mushrooming. The closer your shock tower mechanism is to the ground, the more likely it is that some sort of impact will throw the strut off balance.

The way you drive combined with the low profile of your Mini may also increase the likelihood of strut impact and mushroom shock tower failure. Driving over uneven or rough ground or over potholes or bumps at high speeds can cause impact and mushrooming.
