Will these fit my car and will they sit in or out towards the arch's more?

New rears will have 9mm more clearance inside and stick out 9mm more than what you have now.
Basically everything will protrude more than what you have.

Fronts are right
rears will be 3mm more clearance on the inside and stick out 15mm more than what you have now, so no need for spacers.
I fit 285's on a +39 wheel with a very slight rub on really big bumps, so you shouldn't have an issue with 275's on your new wheels since they are more inbound than mine are.

Code 475 is the system that uses pressure monitoring sensors in each wheel, so no worries for you!
