Need a little bit of feedback on wheel fitment!

Need a little bit of feedback on wheel fitment! Ok so I know which wheels and tires I will be purchasing soon, now I want a little feedback in regards to if you guys think there will be any issues with this setup.
The wheel specs are the following:
18x9.5= +57mm 5x4.75 with a 7.49 backspace
I'll be wrapping these with 285/35/18 Michelin Pilot Super Sports at the rear. I'll also be adding Koni's and Strano springs. Do you guys think I'll be ok or is there a possibility I'll rub?
Also do you guys suggest I go with a narrower wheel dimension up front (18x8.5) as opposed to 18x9.5 all around? What would be the pros and cons to either? Keep in mind that I will eventually be upgrading the brakes on this car to the 5th Gen Brembo's with larger disc brakes.
Specs to the 18x8.5 wheel:
18x8.5= +56mm 5x4.75 with a 6.95 backspace
Thanks in advanced for your help.

a 57mm offset will tuck into the fender well. a 40mm offset will sit flush with the fender. the offset you listed is common. there is no reason to pay extra $$ for the 285 over a 275. I have ran both sizes and they dont look any wider or grip any better. stick with 18x9.5 on all 4 corners!! the Tires, shocks and springs are golden!!! GREAT CHOICES. get CTSV brembo's and save your self from drilling on the spindle. keep in mind spoke design will be an issue regardless of what wheels you get if you intend to use the larger calipers in the future. I use CTSV Brembo's up front with my Forgestar CF5's in 18x9.5 +40mm offset and I have tons of space and no need for a spacer.

stick with the Michelin's on all 4 corners and run 275/35/18 on all 4 corners too. this will allow you to rotate the tires easily. like i said, there was no noticable difference when i ran 275 up front and 285 in the back. thats why I went back to running 275 on all 4 corners.

RedDead do you have any pictures of your car with the 275 all around? Personally I like the staggered look of a slightly smaller wheel on the front but wouldn't rule out going same size on all corners. The last camaro I had i ran 285s rears and 245s fronts, car only saw 3-4K miles a year so the tires lasted about 5 years before I had to buy another set. My current Camaro will be seeing similar mileage so being able to rotate them isn't a deal breaker.

Koni, Strano, big brakes....I'd go with the 18 x 9.5s front and rear.
Why... better grip up front when braking and cornering, and you can rotate them from front to rear. I 'd also go with a set of H&R 20mm hub spacers in the rear. It'll give it the appearance of a set of 18 x 9.5s with a +37 offset, if you want the front to sit out further like the rear then put a set of the same hub spacers up front, plus you gain additional caliper clearance for the big brakes.

so that's two votes for same sized tires all around (275 being the biggest I can go up front i belive). I'll do a little research on the hub spacers, curious to see how a +38 offset wheel sits in regards to the fender. Also, I'm guessing I'll have to buy longer studs as well to compensate for the spacer correct?

No, longer studs are not needed, the spacers have their own studs installed. The only down side with these is that you might need to cut or grind down the factory studs so they don't protrude beyond the hub spacer. This only pertains to wheels that don't have a cavity in between each stud hole.

Here's a photo of the actual H&R #4085704 hub spacers.

Here is my setup 18x9.5 with 40mm offset and 275/35ZR18's all the way around. Strano springs in the front, BMR springs in the rear with Bilstein SLP shock/struts.
Nothing rubs on anything and it drives great.

Hardbones thats a clean ride you have there. Seems like a +40mm offset seems to be flush with the fender. Which looks great IMO, do you happen to have a pic from the rear of the car? Would like to see how those 275s look. So if I do a 17mm hub spacer that would put me right at +40mm correct 99Bluz28?
I have heard that running wider tires up in the front sometimes causes the car to hunt or follow road cracks and such. Any truth to that? That would be my only concern to be honest.

First a correction the H & R hub spacers I listed are 20mm, not 19mm.
With this type of hub spacer I believe you need them to be at least 20mm thick since you'll still need to fit the shorter H & R lug nut within that 20mm to bolt them to the factory hubs. So, I'd still stick with these 20mm spacers, but you might need to roll the rear fender lips for clearance.

Wider tires to tend to follow ruts in the road a little more. You're alignment specs and tire have more to do with how much of an issue it is. A 275 series tire or larger will never cruise like a skinny front drag runner or a Civic with 215 series tires. But these are big cars and the more tire you can put under them, the better they will handle (corner and such) on the street.
