what kind of "good" kumho tires? the only street kumho tires I would consider good is the kumho mx, 711, 712s or whatever it is aren't really serious performance tires. But... if you have them and they are new and you don't want to sell them, and seeing how you already have new shocks, I would replace old/worn out bushings and get an alignment, you could probably check for some good alignment specs on your car on honda-tech or something. After that if you still feel the car rolls too much or understeer/oversteers then sway bars will probably do the trick. Again, you could probably find alot more good info on honda-tech.
