Do I installed some tein springs and shocks and my abs light came on is this bad?.. anyone help my why this came on?

 

There is a wheel speed sensor at each wheel.

My guess is that you either damaged or removed one or more and forgot to re-install it.

Please check all your wheel speed sensors to make sure they are installed and do not have damaged (stretched) wiring.

 

I took off all the wheels and check each sensor by the rotor and all of them are intact and dont seem to be damaged or streched, I cant figure out why the light comes, would it be because the car is sitting to low?

 

No, I don't think too low is a problem. Are the rims and tires the same sizes as before? I think some ABS systems can get confused if the front/rear tire sizes are too different from one another.

 

Theyre the same rims I used before I put the coilovers on, the brakes seem fine I pressed them hard enough to see if they would lock up and they didnt, if i needed new sensors how much would they be?
