"the run flat side wall has no give" therefore the mini suspension is set softer to compensate, by replacing the run flats with a standard tyre, the ride will then become soft, and effect the handling,
one new run flat was about £120, and 4 good year £430, he had no real reason to talk me out of the run flats.
so is the ride softer, and the handling compromised?

thanks(lower & top strut fitted)

The ride will be less crashy, and handling is improved as a result.

He seems to share the common misconception that a harder/firmer ride = better handling, full stop. This isn't the case, it's much more complicated than that.
