What offset works for 20" on a 2013 1LS?

[awdmofo]

I have a 2013 1LS with a few bolt on's, going to get it custom tuned/ported 80mm TB and ported manifold in June. So not pushing anything past 375hp to the flywheel but not stock either. Currently running some black 5-star 18" wheels that I believe are 8 inches wide on some 255/55/18 tires. Not sure what the offset is, but would like suggestions for 20's. Maybe 20x9 all around, or maybe 20x9 front and 20x10 rear. not sure i'll go wider than 265/275 in the rear though, not enough power to need anything wider than 275. Any help would be great

Here's the setup I ran on my 2012 2LS:

20x8.5
255/40R20

20x10
295/40R20


IMO the stance was perfect. I'll try to get pics for you. Don't quote me on the offsets but I think they were +20 and +23.

I run 20x9 +27, with 275/40/20 on all 4 corners on my 2013 1LS.

Here's a shot I took when I was swapping over to my winter set this year.

well you have plenty of room on your car and everything from a 20et -35et front and 35-45et rear will work easily just depending on wheel width.

example below// Teal FS01
20x10 23et front and a 20x11 43et rears






M716 ( ZL1/1LE style )
20x10 23et and 20x11 43et

was it a dog as far as power and MPG after you went that big? I'm thinking of going 20x9 all around and maybe just a little wider in the rear as far as the tire size.

Do you think that If I lower it 1 inch all around a set up like yours would fit and work fine?

Sick looking, I like the lowered Camaro but its a little too low for my taste. Basically im thinking of going 20x9 all around and maybe just a little wider in the rear as far as the tire size like 245 or 255 up front and 265 or 275 in the rear. Its a V6 that will be tuned in june but wont go past 380 flywheel HP so going past 9" wide in the rear I think is over kill.

I was thinking of going with Giovanna Haleb 20x9 black wheels at 35+. not sure if that will fit right though, not very familiar with offsets like this, I was with my Tacoma and they use the term back spacing and its done in inches lol.

Has anyone used 20x10+34 on the front of their Camaro?

I feel like it would still fit when lowered, as there's a little room. Hopefully someone else can answer you definitively.

When you are ready to pull the trigger, talk to a vendor. They are knowledgable and can help you a ton!

The look that you seem to be going for is very similar to the z28. You should grab some z28 repros from one of the vendors here, and it's a tried and true fit and finish on your car. And they will know what offsets, what sizes, what tire sizes, everything will fit.

I don't believe the +35 would work up front, and I highly recommend doing a square set up so that you can rotate your tires

Yea I looked at the Z28 repo's, not excatly what I was going for but they are growing on me. I just figured 20x9's all around should be good, hell even 20x8's would be nice with 265 wide tires. still shocked you are running 275's and they dont seem to be too wide for an 1LS like mine! Chibi, as always good advice.

I think the 275s fill the well perfectly. I've been super happy with the set up, and cornering on a much wider tire just feels so much better.
