245s will fit on an 8.5 in rim. 19 in rims with 45 series sidewall is a lot taller than stock (stock is 225/55/16). The tire calculator I regularly use is showing that 245 45 19s is almost 2 inches taller than stock

It should physically fit on the car, but the large diameter is going to throw off how the car drives and possibly wear your old suspension parts out even faster. Since you haven't mounted the tires yet, try to return or exchange them for 245/35/19.

It comes down to how many details you notice while driving. The car was designed to have a 25.74 diameter wheel to have everything balanced. Now you're raising the diameter to 27.68, so the oem parts aren't in their normal range of operation, so they'll wear faster. The same potential for damage is true for every car modification. The difference in this case, is that rims and tires are moving parts, so things are accelerated. That's why everyone tries to keep the same over all diameter regardless of what size rim they choose from stock 16's to 20's.

Realistically, the only thing at risk is your wheel bearings, but these cars are old, so everything is already a little beat up. Anything out of the norm can cause damage and become a domino effect. In my opinion, getting the right sized tires to prevent this is a small price to pay.

I finally found some wheels I like, niche milan, what tires do you recommend for 19x8.5 frt and 19x9.5rr +35 offset on all wheels? Assuming I have coilovers will i have any negative camber to fix also? Trying to figure out if I need camber adjustible coilovers too, thanks.

Assuming nothing goes wrong, do you think the large 45 sidewall will look weird on stock suspension?
I know a lot of people suggest 245 40 r19s front and back, so maybe that would be a better setup?
Will 245s fit in the front without rubbing on sharp turns?
Thanks.
It is going to look really weird on any suspension. The larger diameter tire is 2" more than stock, so your car will be 1" taller off the ground now. People suggest 245/40/18 and 245/35/19 tires. Those are the 2 sizes that are closest to the oem diameter. At stock height you shouldn't have any rubbing issues.

Lowering the car will always add negative camber, but the stock arms have minor adjustment. Needing adjustable arms depends on what you consider too much negative camber. Also, camber adjustable coilovers are useless with the suspension design of our cars.

Although, I am not sure how it would affect turn in, you should be able to run 17x9.75 all around. And, depending how low you are, with this setup fenders would need to be rolled all around. 255/40/R17 would suffice for the fronts.
