When you lower your car the tie rods are not parallel anymore the bump steer kit lowers the outer tie rod end so it is Parallel again eliminating bump steer
A better description here
Better yet here is an explanation of what bumpsteer is so you understand what it is and why you may need it:
If the tierod on your car isn't aligned with the lower control arm what will happen is on either bump or droop the front tires will either toe-in or toe-out excessively making the car seem "twitchy" and unstable. If you're driving it normally then it isn't so noticeable since it's happening at a speed that is manageable.
When you are going fast all of this takes place at a much faster rate which makes the car harder to control and feel more unstable.
As BraMas said, the kit just re-aligns your tie rod so that it minimizes the effect.
At least that is how I understand it......

im still a bit confused though.. so this will help adjust my toe angle back to how it was when stock??
so than this would help my tires to wear normally correct?? cuz at the moment, i have 15k on my tires and they look almost dead... my friend has the same tires and maybe 10k on them and they look brand new.. and my tires are cracking on the outside due to my huge steeda sway bar?? i was told a bumpsteer will fix my tire issue and such

no a bumpsteer kit isn't really going to do anything for tire wear.
Do you know what your cars alignment is?

no i dont know what it is i should have asked for the paper..
my alignment was JUST done though... bc i hit a curb a while back in the snow and i had to bring it in to check if it was alright.. but i didnt drive more than 15 miles after hitting the curb.. i just had to drive to the shop..
turned out that i f*cked something up, but they fixed everything... so i know alignment is perfect.. and wheels are balanced bc i did them myself
i've been told its my big steeda sway bar thats causing the outside of my tires to wear
I've got 1 for sale its a UPR extreme bump steer kit brand new never installed PM me if you want it. Its yours if the orignal buyer does not send a payment tomorrow and its 80 shipped.

I'm no suspension expert by any means, but I fail to see how a swaybar would affect your tire wear. From what I understand, it has to do with the camber you set your alignment at. Since you lowered your car, if the alignment tech didn't compensate with some negative camber anytime you go into bump your tire will go to positive camber and will wear the outside part of the tire more than the inside without a bumpsteer kit to adjust the tierod to the proper length. The way the bumpsteer will affect your tire wear is over many miles the excessive toe-in/out will wear the tire abnormally. The kit should correct that along with a little negative camber. I'd go maybe a degree and a half or even 2 negative.

Wait so the outside of the tires are wearing not the inside?

i dont THINK the inside are wearing.. i can check since 2 of my tires are mounted on my new wheels in the basement...
but the outside are like "cracking" if that makes sense.. it just looks like they are under a lot of load i guess
and thanks E714FEVER, if i decide to get one, ill PM you to see if you still ahve it i jsut wanna make sure this will fix my problem. but its not looking promising
looks like i'm going to have to tell my mechanic to adjust my toe angle or something
