Another comment on some things being tried with the wide 2wd fronts I have seen others doing has been to run the wide fronts on slim wheels. This gives them a bit more cushion on the tire, also seem to keep the foams from going soft as quick. We noticed that the foams definitely feel quite different between a fresh set versus a used set, so if you find you tires themselves look good but your handling doesn't feel the same, check the feel of the foams.
