You have some options on shocks and springs. Your best bet is to stick with the OEM shocks since they come in three different styles. Those styles are:
- Base
- Sport
- Euro
Those are arranged by stiffness with the Euro shock being the most stiff. I have the Sport shock on my LS and it is very controlled. There isn't much in the way of aftermarket shocks other than Monroe Sensatracs. I would not recommend them. I had them on my car and it caused the car to float too much. Now, you can look into a fully adjustable shock like a LEDA suspension shock but you are looking at $400 a shock. It all depends on your budget. We sell the OEM shocks on our website.
As for the springs, there are several companies that make a lowering spring. Eibach sells a spring that will lower your ride about an inch all around. Companies like Intrax and Springtech sell springs that will lower the car even more. These lowering springs will help lower the center of gravity of the car and make it handle much better. Not to mention though that the car will look better as well.
A good combination of shocks and springs will really help your car handle and perform like it should. Also, it all depends on your budget as well.
