Just wanting to make sure this set up is doable. 20x10.5 +35mm Wanting to run 305/35s all around. Car is on the pp2 suspension and not lowered. Everything I’ve seen says it should fit fine. Thanks guys

I should’ve mentioned this is on an S550 2016. Going FI next month and need more traction for roll racing. This will be a daily driver so I’d rather have a squared setup. I’m on 285s now FBO E85 and have traction issues on sport cup IIs

There's a reason the PP2 rim is 24mm offset. You *might* get away with 30 but 35 is very likely NOT to work. Also 305 up front will likely rub the strut with that much offset.
I don't see how your solution is going to help if you can't even get N/A power down.

If I found a +25mm offset that should work better? The thread below everyone is running square 305/35 with no mention of spacers. Would a 20x10.5 +25 with 305/30/20 work better?
As far as traction I’ll end up toying with some suspension upgrades down the line. Most of my issues come from a dig not a roll.

indeed https://www.mustang6g.com/forums/threads/pp2-tire-sizes.147236 shows that 305/35r19 on ET24 front works fine. Running the same outer diameter setup as mentioned in a 20" size and similar offset should be fine as well. Most people bump up to 19x11et24 (or 50 with 25mm spacer and extended studs) for fattest tire application. If you haven't done the 'stop the hop' mods, you really should start there.

How old are the Sport Cup 2s? Thise tires need heat in them to work, and if they have too many heat cycles they’re ice skates.

305 aren’t much grippier than 285s in reality. Tire coupound and age makes a lot more of a difference.

10.5 ET 35 with 305s might fit with a 5mm spacer up front, but when we’re talking about clearances that tight, I’d want to know the specific tire model in question. They’ll poke a bit in the rear. +25 poke in the rear more but will fit up front much more easily. I don’t know how the 35 profile tires changes things tho.

square 11”s with 305/30 tires is easy with any number of common and not so expensive 11” wide wheels, but you use a front extended studs and a spacer (and maybe camber plates).
