Need more details to give you an accurate response. Is the car lowered? If so How much? Camber arms? Wheel specs?

Would be interesting to know if the 35 AR would help dampen some of the vertical chatter while daily-ing on stock suspension and wheels...

35 makes the rear wheel bigger then the oem diameter. I’m on 255/35 front and 285/30 rear and love it!

^^^^235/35/19 is too small a tire for the front of your ISF. 245/35 or 255/35 would be a better choice for your stock 8" wheels. As mentioned 285/35/19 is taller than stock, the OD is almost 1" larger than the stock 255/35/19 rear. When I ran stock wheels on my 2008 ISF I ran a 285/30/19 tire on the rear and it worked for me, however some others with stock wheels and that size thought it felt squishy. Tire manufacturers do not recommend a 285 cross section tire on a 9" wheel. 275/30/19 however would be fine and a lot of folks with early stock wheels run a 245/35 or 255/35 front and 275/30 rear combo.

I'm running stock rims 235/35 and rear 295/30 if that helps any (no rolled fenders and stock suspension). No rubbing and about 1500 miles so far on a new set of tires.

I've done some searching but need some advice from the tire/wheel fitment experts. I have a 2012 IS-F with KWv3 lowered just just slightly in the rear and looking to put 19x10.5 +45 wheels in the rear. My fenders are already shaved a little bit but it rubbed on dips with my previous set-up (19x9 +25 on 255/35-19 Michelin PSS).
Can I use a 275/35 or will it rub? The reason I would like to use the 275/35-19 tire is that I already have it, and it has good life/tread so don't want to buy a new tire if I don't need to.

Front fitment is 19x9 +38 255/35-19 Michelin PSS and more info can be provided if needed.

Another consideration is that a 235 front, 285 rear combo will exacerbate the ISF's understeer at the limit. IMO, if you care about how your car handles, I would avoid increasing the front-back stagger over stock and go with combos suggested above by Lou and ISFpowered.

in my case,
2009 w/ around 7,800 on the odometer on factory wheels 15mm spacers a/around
eibach pro front springs, rear stock springs Fr & Rr stock dampers.
tires Fr 235/40-19
Rr 265/35-19
no fenders mod, no rubbing and rides better a little more compliant.

Who put the rears on for you? ...probably not a good idea to put 295mm on a 19x9 wheel...unless it's a mall cruiser.

Gymkata

Why are you asking about those particular sizes? They will probably fit, but it doesn't make sense unless you have a cheap set of tires lined up and don't care about performance.

Bumping for info/input.

Theoretically, your proposed wheel is 19mm wider on each side but your new offset will bring it in 20mm so the face of wheel will sit 1mm in more. So if your current setup rubs, chances are your new setup will rub at least the same amount, but likely even more since your new tire will be taller.
