Wheel sizes without modifications for 2019 2SS

We just got our first Camaro. It is a 2019 2SS, it is completely stock with the 4 piston Brembos and without magride. Needs tires badly. Might as well do new wheels now also.
Question is:
What exact size/specs do we need to run 305/30 r20 rear and 285/30 r20 front?
Do not want to do any mods or spacers.
I have searched but cannot seem to find a exact answer and my knowledge in this department is very limited. Best guess at this point is 20 x 11 with et43 for rear and 20x10 et23 for front. I do not want to rely on whatever the tire guy comes up with, because I know that you never know who you will get at the counter. We are new to the area and do not have a trusted installer here that we would feel comfortable relying on their information.

to the forums, puma1973.

Check out https://www.wheel-size.com/size/chevrolet/camaro/2019 and scroll down to the 6.2i section.

One of the absolute best wheels you can get are the forged SS 1LE units that some of us run or upgraded to. It has similar specs to what you mentioned, except their front wheel offset is +20. You should also be okay with +23, though, if you want cheaper aftermarket wheels (such as MRR).

By the way, double-check lug nut opening sizes if you go aftermarket, some (such as MRR) are smaller than stock and you can't reuse your lug nuts as no tool will fit in the holes, you need to buy specialty ones (Gorilla, for example).

Yep, what arpad said. Basically you are trying to replicate the SS 1LE rolling stock, and that version has the exact same fender openings you do. Except it also has magride, which takes up a bit more space on the inside compared to your car. The stock SS 1LE fronts are 20x10 et20, but 23mm offset will still fit your car. Make sure the bolt pattern of whatever you get is still 5x120 (not 5x120.65), and that the hub pilot bore is at least 66.9mm. The stock SS 1LE wheels obviously meet all these requirements, but if you go with some other choice, just make sure they meet those specs.

there were some free tires in Florida (port homassa?) on either this forum or the FB page, might look for those.

and craigslist has ZL1/1LE tires pretty often.

these rims seem like the deal of the century:

Thanks to you both for the info. This helps a lot. Normally I research things to death, but being we just got the car, and the tires are shot, I need to get moving to get things ordered and scheduled for install.
Would like to go aftermarket, just to be a little different. Other than the MRRs, any top recommendations for black wheels?
Also, car will be strictly street, no plans for track, unless maybe at some point it is a 1/4 mile straight one.

Apex is a real go-to manufacturer for 6th-gen wheels. They have "flow-formed" wheels that are nice and a good price point, and also some forged options that are nicer and more expensive. Forgestar may also have some flow-formed options for you. BC Forged are forged, nice, and more expensive. Kinda depends on your budget. MRR is definitely on the more budget-friendly end of things.

Just to point out: those are 19x11 and 19x12. They will fit a lower-model Camaro with careful tire selection, but they will also poke a bit in front. I feel like this isn't where the OP wants to go with things, but maybe he does.

That said, it would be worth his considering 19x10 and 19x11, with SS 1LE offsets we already discussed. I run a set of these for street driving and rain autocross/track use, and you just "+1" the aspect ratio for tire sizes to get the same outside diameter as the SS 1LE (285/35/19 and 305/25/19). MRR used to make ZL1 1LE replicas in this size that look good, fit, and are cheap; but they haven't sold those in several years. I have three sets of those for various uses.

Again, awesome info. I should have stated earlier, budget of up to $2k is probably ideal, although never know once one is spotted that has that "gotta have it" appearance. This is like most "hobbies" I get into, once you start down the rabbit hole....
