YYZ's are arguably one of the best springs to have a decent ride and I've had both stiff walled tires and softer wall tires and that alone makes a huge difference between a harsh ride and relatively smooth. I always go for performance though and am now riding on summer tires with a stiff sidewall and not to forgiving in bumps. I have some links for you nowachevyowner as to why the coilovers are worse than YYZ springs and Koni's.
