    what all parts are recommended for lowering?

    Ok so once my income tax check comes in i will be putting my stockpile of goodies on the car all at once. I have Strano springs and koni adj shocks but what else is recommended when lowering. I have umi Adj lca's and relo brackets,umi adj panhard bar. Is an adj TA required or can i get away without it? Also does anyone have the umi drag rear sway bar? Oh yea and i also have umi 2 point sfc. All the parts i have are brand new and still in the bubble wrap,(chrome moly as well),ive been stockpiling for about 9 months so hopefully its about to pay off.

    If you are lowered, you've changed your pinion angle. An adjustable torque arm will allow you to reset it to the correct setting. Usually it is set to -2 degrees. This is where it is set from the factory at stock ride height.

    The reason you set your pinion angle is to compensate for the movement of the differentials pinion of the car under load. The goal is to create a straight line from the back of the crankshaft through the transmission, drive shaft, and the pinion of the differential while the car is under load. A negative pinion angle is commonly set due the the tendency of the pinion of the differential to raise while under load. You set a negative angle for that pinion to sit at rest so when the car does come under load it is hopefully at your goal...a straight line.

    Here is a site that explains it in more detail and how to check it/set it.

    Don't forget to realign the front wheels too. And Yes on the Adj torque arm

    while you have the struts out not a bad idea to put some good control arm bushings in as well

    Hmm where can I find those bushings? Are there any other suspension parts I might have left out?

    i got energy suspension polyurathane bushings at summit racing for $60 but you can also get the prothane brand for like $45 i think it dose upper and lower control arms for both sides keep in mind the are a bitch to do and its easier to just blow the rubber out with a torch but instructions and grease are included but the energy suspension brand has better instructions as far as what to to reuse and trash

    Pretty sure that lowering changes the camber, caster, and toe of the vehicle depending on how low you go.

    You do not need a kit, just an alignment.
