Question KFX suspension upgrade

What kind of difference would i see in handling if i were to order front and rear strut bars off KFX along with the KFX rear sway bar, and put a front sway bar in from a 2003 Tiburon (sport model) (Heard on StreetKiaz they were compatible) and would i need to upgrade my struts/coilovers etc.

The front sway bar is sufficient but you would greatly improve your handleing by getting a bigger sway bar. The stock bar is only 13mm and looks like a piece of spaghetti. The KFX bar is 22mm if I am not mistaken, which to me is overkill. A 2003 tiburon GT rear sway bar is 19mm and a direct fit. It will greatly improve your handleing. If your lucky you might find one in a wrecking yard, but if not you can buy one from a Hyundai dealer for $100.00. Make sure it has a green dot sticker on it meaning it is a 19mm bar. There is also an 18mm bar that has a red dot sticker on it. Along with the tiby bar get the tibby end links too because they are metal and the ones on our cars are plastic. Also get some urethane sway bar bushings to finish everything off. Coilovers are great if you can get the right spring rates. Most of the springs that come with ccoilovers are really stiff and give you a pretty piss poor ride. They are great for the track but not so good on the street. I have a set of coilovers and they the ride was so harsh it would make my CD player skip on bumps. I took them off and got some softer springs. I'm going to put them back on to see if the ride improves. You can also buy some lowering springs which kill two birds with one stone, meaning your ride sits lower and the springs are a little stiffer which improves handleing. You may not have a car that will burn up the asphalt, but it will handle like one.
