I will tell you from my experiance, there is a hell of a lot more to it than springs to make your car handel better. My susspention upgrade... Flamming river sortsman quick steer steering rack kit, Ford racing lower front control arms, Hotchkins rear upper and lower control arms, Eibach 2'' lowering sport line springs, Eibach front/rear sway bar kit, Eibach strut kit, Steeda adjustable caster/camber plates, and all new bushings. Know dont get me wrong this made a world of a differance over factory but after something still felt off. I was having a bumpsteer issue witch is the angel of the road dictates were your car goes. In other word the road steers the car as do bumps you hit. So after some research i found steeda also made longer front ball joints to bring the front control arms back in alinement with the road along with adjustable outer tie rod ends, these one are hight adjustable. With these you can aline the sterring with the control arms all horizontal to the road serface. The car connering capabilites i have yet to find a limit to. I did dump a lot of money into this project but it was worth it. So in short.... lowering sprints will make a differance, but you need a lot more to get the proformance you think you would get with just springs. After that i installed a complete axel ass with 3.73 gear and an aluminum drive shaft. Giddy Up!!!!!! |
