ok so i just put some lowering springs on my car and now the steering feels loose and i have a vibration at high way speeds. no the vibration isn't a wheel balancing problem i balanced the wheels my self. i was wondering if anybody had run into this or had any ideas. other than that car rides great.

 

could be a bent rim. they can ballance, but the rim will still wobble if it's bent.

it happened to my car once.

 

so i checked my wheels and none of them are bent anybody got any other ideas

 

Did you have an alignment done after the lowering springs were installed? If not you should. Depending on how far the car is now lowered, you are riding more on the inside edges of the tires and this can affect the way it drives and handles.

 

What drop kit did you use? A crappy one would explain the vibrations and maybe the steering.

 

yes i did get alignment done and everything went into spec. as for what springs i used i don't remember off the top of my head (i got them for christmas) it was a 1.75in drop. might have been i little much with my 17's, anytime i make a turn up an incline my tire rubs on my fender which sucks.

 

That is really unusual... usually after lowering you should feel the car more tight, not loose.
Check your alingment on another shop, note the specs for camber and toe in, and the shop has to consider the car is riding on lower springs and on 17"s, and with that I don't mean they have to do anything special, just put you on the more negative limit of the camber (not more than -0,5 per side) and check the toe in, you would want a little "toe in" that is tires should be a little towards the center of the car, not more than 1 degree per side, and not less than 0,5 degree to the center.
Also check the tire pressure, maybe they over inflated your tires... also important, for the alignment, you should check tire pressure COLD, and BEFORE alignment. A good way is to inflate them a little higher in the night in the closest service station from your home (or inflate them with a portable inflator, but that's a PITA) and wait until the next morning to check pressure, so that you are sure tires are really cold and you can deflate the excess pressure from each and leave them all even. Remember also the rear wheels have to be aligned also.
Let us know how everything went.

 

If everything looks fine, it could be your tire gone bad. If tires have some defect on the sidewall, it causes a lot of vibration.
