go for it, they have height adjustment and damper adjustment. Well worth the money in the long run. Plus you can add after market springs later down the road, but that is a debate for another thread lol.
I had the same problem when I first got mine. What I did was replace all the struts and the handling issue went away. KYB has a good kit. If you have the money add some performance bracing. It may put some understeer back on, but it will be waay more predictable.
