I run Silverado SS 20 inch wheels on my Silverado.

I have Summit three inch drop springs in the front and a Belltech 4 inch drop out back.

I have been having issues with the inside of the front tires wearing out. I have had several shops put alignments in and Im a little frustrated with it.

I know drop springs are hard to get aligned due to the change in the geometry.

When you center the wheel and let go of the wheel, it wants to pull to the ditch, but all the techs say the alignment is within specs.

Anyone have specs that I can take with me next time?

 

That's the nature of the beast I have 3 in coils and I'm so close within in specs its just that close. For you to get perfect and stay at 3 " u need a 1" drop coil and 2" drop spindles but with that u loose turning radius a lil.. and with the wearing of the tires you will get that only advice on that is to rotate after a few hundred/ thousand miles . And it will pull to one side no matter what that's another beast that has to be fixed by changing your whole front setup.
