ok the wheels are now placed but I have a weird feeling when I was test driving it. When I brake or accelerate everything goes perfectly but when I drive to a bump the car kind of jumps to the right. ?????

What might cause it???? The wheels are the same size in front as OEM wheels and on the back they are et 35 but with 10mm+5mm spacers. I think I am going to order the 15mm spacers just to be shure but what may cause the jumping???
