The manager did say there is only 1 adjustment they can make, and that's all they can do without adding a drag link(?) to give it more adjustment. My counter argument was if it drove straight this-morning, and it's not the alignment it must be the tyres - there answer, it's not the tyres as they are brand new, maybe your old tyres were worn and now with new 'flat' tyres they are not compensating for the suspension. And we went around in circles on that point.
Thing was, the old D693's wore even and had zero scrubbing inside or out on any of the 5. They still had about 3mm left but started to get a bit squirrely in the recent rain, hence replacing.
