what are u some of the advantages of using tubular a arms? i know their lighter, but will they make the car handle better or what?

 

YES. Since they are lighter, they reduce unsprung weight, allowing the suspension to react faster. They are also quite a bit stronger than the stock pieces resulting in less deflection under load giving a quicker suspension response. The less the parts deflect, the more efficeint the suspension. If suspension parts deflect a lot, power to the ground at launch is absorbed as well as braking power at shut down. If you like to auto-x, you will definetly notice a difference in handling. On the street you'll probably notice a bit harsher ride, but it is soooo worth it.

For a-arms that you plan to use on the street, I'd stay away from chrome-moly. It is just too brittle and with all of the potholes and bad pavement in the world, a control arm failure at highway speeds could be disasterous.
