Will 315's on rear require new alignment specs?

Sorry for the dumb question, I am lowered 1" with a great alignment now on stock wheels, tread wear is even all the way across on rears. I have F14 20x11 rear wheels coming and 315 tires, will I need different alignment specs? Thanks!

No alignment needed but this setup is only feasible when dragging... if you drive/corner aggressively or run road courses there is a high posibility of breaking the bead if u run factory rims because the even though it fits the 315 is too wide for the factory rear wheel.

Thanks for the replies guys. I figured the alignment would be fine just checking to make sure. The 315's are going on 20x11 F14 rims, so no problems with bead.

315s on 11 inch wide wheels may have rubbing issues if the offsets are not correct.

I absolutely insist on anyone I do drop suspension systems to get an alignment. Camber and toe change a lot when dropping springs. Tires are too expensive not to get an alignment check

it appears that he is already lowered and aligned and is only changing wheel sizes..def agree, anyone dropping needs alignment...

The alignment should be fine,but they may rub.we had to install some coil overs on one car that had drop springs and the tire and wheel set up due to rubbing.

The 315 35 20s are the same heighth as the factory stock 20s. The only thing that changes is the contact patch. I wouldn't think that would require a 4 wheel allignment.

Thanks for the replies and insight. The wheels are ordered with offsets specifically for drop spring Camaros. So far I have not heard of any rub issues with this wheel/tire combo with the correct offset numbers.
