Understeer
1) check your alignment. Make sure your alignment is set up properly.
2) How are you entering corners? If your going in WAY TOO FAST, then it really doesn't matter what your driving the car isn't going to turn.

Most people set the front too stiff for some reason. It's probably because they think it makes the car corner flatter (it's true a car set up like this will roll less, but your handling will suffer). Most guys with coilovers make this mistake.

SanfranEvo,
It's not just the front being to stiff/soft. You need to see what the tires are doing. Remember it's the tires that touch the ground. Check the roll over on the side walls. If the front is rolling over to much you will push. Only add as mush roll stiffness as you need. To much and you will lose traction, too little and you will lose traction. If the rear is to stiff you will lift the inside rear tire off the groung and the cornering speed will drop. Then you may need more front spring rate. You can adjust these things though camber,toe, springs, struts/shocks(adjustable valving), sway bars and tire pressures. Contact patch is every thing in cornering. The trick is to find the balance front and rear. My set up right now, has the front and rear tires rolling over on the side walls about the same. But with out corner weighting the car it turns a little faster on left turn than on right. Adjustable coilover wil fix that. With the Teins you will be able to corner weight your car,that can take some of the push out. Start at the rear. add a adjustable rear sway bar. Stiffen it up till the rear lifts, Then go back to the the next softtest setting. That will help the rear. Check you camber.You will need at least 1.5*on the front. toe 0*,1*and 0* toe on the rear. Check the roll over on the front tire. If you are rolling over to far. Passed edge of the tire tread. You can add air pressure, stiffer front sway bar, drilling a new hole in the stock one will work, thats all i did. It takes time to set you a car, you can't just throw a set of coil overs on it and hope it will go away.This is the easy way of showing you what you need to do, Weight transfer is what we are really talking about,get that under control and adjust it for all four corners of you car and you will corner faster. It still may push a little at high speeds, You realy don't want to remove all of it. You just need the car neutral. Only trouble is, you make a change on one end of the car it will change the other. Thats where it gets hard. If you or anyone needs some more help you can PM me.
