Most people don't know this, but when a car has 18" rims, they have to soften the suspension to compensate so your rims don't get so easily bent when you hit a pothole. They do this on the new mustang GT if it's ordered with 18" rims. It has a different suspension.
I am also pretty sure the suspension is softer on dodge trucks that come factory with 20" rims based on how it felt when I drove one.
Sorry no disrespect, but I am going to have to call you out on this, trust me I know. Like I mentioned before my former employer was smack dab in the middle of the MotorCity. We never made the suspension softer on a sport coupe if the rims increased in size. The whole reason for larger rims is for performance (and I am not talking Bling Bling rims ether). That was the biggest complaint by the customers after buying the top of the line coupe “The ride is to stiff” well no sh** you bought a 400+ horse street legal race car, what did you expect… Now on the high end luxury sedans, yes we would soften the suspension for a better ride if it had larger rims, but we would still get complaints. You want a softer ride by a V6 with 16 in rims (larger side walls)…
