when it comes to handling, just a few tweaks to the factory setup [shocks, T-bars, etc] is all a guy needs.
a huge difference can be made upgrading what is there at a modest cost versus ripping the factory design out and spending buckets of cash on the latest wiz-bang coilover/four bar whatever flavor of the week suspension system that looks kewl, but works way less than the factory setup.
somebody at one time stated : "stick with stock, you will be better off."
sounds good to me.
