The wheel rate will usually be much softer than the spring rate. The solid axle will have the two rates nearly identical. I mention this because (assuming the lengths would fit) a given coil over unit that rides great in an IRS car will be very much stiffer if moved to a solid axle car. Regarding ride comfort only, as long as both systems will allow 5-6 inches of wheel travel (without binding control arms or unwanted contact to frame or body) both can be made to ride well. The IRS will have the advantage when on rough pavement because of much less unsprung weight but, other than that ride can be nearly the same as IRS. There are a lot of other advantages to IRS regarding geometry but to say a solid axle car can not be made to ride reasonably is crazy.

I can only reiterate my experience building two 69 Camaros. The iRS car had a much better ride than the Ridetech four bar. Night and day. Even had Bret the owner of Ridetech ride in the car and suggest changes. No real difference. Maybe the solid axle cars CAN ride as well as an IRS but I’ve not seen any commercially available suspension kits that do….
I see that Roadster Shop is now offering a chassis optimized for ride called the Ride Line. I was contemplating buying one for my 59 Chevy pickup to compare to my C5 IRS equipped 56 Chevy pickup. Unfortunately they are now quoting 10 month delivery times which is a little bit crazy imho….
