Hi there, if you installed the coilovers the way they came out of the box there should be no problems with the topmounts.
I have the exact same problem with tire rubbing to the chassis. It is indeed strange that it is ony when you turn to the right. It doesnt really bother me much and I keep it in mind, but it could be a problem when you bring the car to your countries MOT, I had to change the wheels for some thin spares to make it pass MOT
