ever since i lowered my car (kg/mm super sport), whenever i slowly come to a stop, my tires make this loud wobbly noise, causing lots of vibration within the cabin... does this happen to anyone with lowering springs?

i had an alignment done and the rears are back to specs, but the fronts are not...

 

Different springs won't make the car wobble. Take your wheels off and put them back on very carefully. That will probably fix it.

 

Fronts have to be realigned. Sounds like the same symptoms of a worn tire.

 

It's because your wheels have more camber and the tires are riding more on the inside edges. You may have had some feathering or uneven wear on the inside edges prior to the lowering, which has become much more noticeable.

You need to get used to it or get camber kits front and rear. New tires will eventually do the same without camber correction.
