Can anyone confirm the stock ride height (from centre of hub to wheel arch) on the rear of a TA22?

I have two sets of springs that I believe are stock. I measured 350mm (hub to arch). Can anyone confirm?

(Reason I'm asking is the person who sold me an aftermarket set of springs is swearing they are superlows. But these are anything but 'superlows'.)

Alternatively, can anyone with 'superlow' springs tell me what their hub to arch measurement is?
