True but not when you really need it.
I just thought it's important to clarify that we do have the full 510mm of width of rear tires (2x255mm) even without an LSD. The only time you have 255mm or just one wheel pushing is when one wheel loses more grip than the other.
Or more accurately, when the difference between two rear wheel's rotational speed is greater than a certain factor/percentage.

So I have decided to stick with the stock 18s. But I am still going to get PSS put on them and am thinking to bump the tire sizes up. Still have stock suspension and non-LSD. Any final thoughts on this before I pull the trigger?
fronts from 235/40 to 245/40
rears from 255/35 to 265/35

Good decision

Rolling the fender lips is a common fix used on Porsches and you can pick a a good 3/8" to 1/2" of clearance. Unfortunately the design of the C63 fender lips and wheel well liners don't allow rolling. Stick with the LSD as your first mod. I tried the bigger tire solution on a C43, C55, and C63 with minimal success, so I offer my suggestions from experience.
