Looks like Original GM 2017 1LE wheels are 20X10 ET20 / 20X11 ET43.

My question: Will they fit on a stock 2016 SS without spacers (especially the front)?
I'm asking since a quick calculation show that the front rim is 14.1mm closer to the suspension.

Thanks

Standard offset for a 10" wide wheel up front is 25mm. Which is about 19mm closer to the strut.
A 20mm offset actually gets you more room, but with the extra push out I would be careful with fender clearance when lowering.
A number of members have put 25mm spacers up front which pretty much gives the same effect. Not sure if they are lowered.

Yes, they will fit fine.

yes sir they will fit fine and if you want a good deal on oem gm ones check out thatgmpartsguy.com he sells them but they are not cheap!

Thanks guys! I was looking for wider wheels / tires in order to get better track day performance, that's why I'm not interested in spacers.

I wonder why some other threads kept talking about front spacers? Maybe they were not interested at a wheels with the same offset.

Also, I wonder if it's worth spending $500 on each of these wheels or just buy good light weight O.Z for the same price?

They will work there is a member that is using them, pricing is up there but def doable.

Can I deduct/assume that most 10" (19/20) wide front wheels with offset of 20 will fit?

Yes sir, it all will factor on the X factor of the wheel, however I have done applications with a 10" ET 28 and they clear the strut and all so the ET 20 provides more clearance to the caliper and strut so it works out fine.

One last question (please) : Will I be able to run 285/35/20 tires with 20X10 ET20 setup or I'll need to drop the tire size to 285/30/20 ?
Same question regarding 275/35/20.
Thanks!

You can do a 275/35/20, for the 285 I recommend a 30 profile tire to be safe.
