rubbing in front

[67txcamaro]

i have a 17" x 8" 0 offset with a 265 40 17 for suspension i have stock upper and lower A arms with a 2" spindle drop and 1" lowering spring. i have rubbing when i turn right and left in front and back of the tire and also when i hit a bump while driving it feels like its rubbing on the top of the tire on both sides.

Can i get away with just replacing the springs or can I change to a 245. Thank you in advance for your help.
