I want to know if Eibach springs will help cure the understeer a bit or should I just hold off and get coilovers. I know coilovers make the car a lot stiffer but for the price of coilovers, I can get Eibachs and Cusco Sway bars. Please help me out here, need to know by tommorow, Friday. Thanks again.

 

Thanks for replying!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Not an expert, but neither will neccesarily fix understeer by themselves. That is a function of tire widths front to rear and the stiffness of the front vs rear sway bars. Putting wider front tires or a softer front bar on will help.

Again, not an expert

 

Eibach's will help a little with weight transfer and lean but not nearly as much as a proper set of coilovers like Tein. The shock is the cricial part as is the relationship between the spring and the shock. Changing just the spring will yield very limited improvements in handling.

 

I think the Eibach front springs lower the car by about .8" which increases the negative camber in the front and could really help with correct tire positioning in the turns, thereby reducing understeer. However, I think the Eibach rear springs also lower the rear, which, depending on the initial setup, can once again increase the rear traction and bring back some of the understeer. Typically, one would want to match the springs, shocks, and sways for the specific conditions that are being run (for optimum performance). Obviously that won't really work on a daily driven car, so you will just need to tradeoff lower performance in some conditions with increased performance in others. A well designed, non-adjusatble, setup, like the Nismo, or an adjustable setup like many of the others, can really help even when only shocks and springs are used.

Springs only can also help, but typically not as much as a full setup. It may be that the springs are a good place to start, since they are fairly inexpensive, and from there you can add new components as you learn what you like and don't like about the car and as more money comes rolling in.

At least from what I have been reading.
