Unfortunately, modifying our cars is not an inexpensive hobby. Pretty much anything you decide to do to your car will cost. I'm always an advocate of putting good shoes on your car before anything else. Too many accidents are caused by people who overdrive their cars with their new mods and are on all-season tires or something cheap and generic to pass inspection. Pay the money, buy something that will keep you squarely on the road. My recommendation is a set of Falken Azenis. Also, if it's not equipped with an alarm, definitely install one. You don't want to go modifying your car and then have it all stolen before you were able to put something in to help deter theft.
