The firmer Red bushing will reduce the movement of the rear diff relative to the rear cradle. This would result in a slightly more planted feel during spirited driving. The trade off would be increased noise transmitted from the diff to the rear cradle. That could increase the cabin noise level.
Based on your description of your driving style you would not gain anything from the Red except the bragging rights of having it. IMHO
