Camber and tire noise
 

I recently lowered my car a little more, and adjusted angles. Toe in is 0 front and almost 0 rear, camber is -2.4 degrees front and -2.1 rear.
Tires are Michelin PS4 (not PS4S, not available in EU in 18" measure).
I noticed a lot more tire noise (I was -1.5 front and rear before), is it normal?

Did you change any parts to to get the camber and height adjustment?

I have coilovers, with adjustable camber plates, but I had them before, too...
