Loving where this conversation is going gents. I had the pleasure of speaking with Cem over the phone this week, and he gave me some great insight as to what wheel and tire specs enthusiasts are after, along with some of the nuances 6th gen owners are dealing with.

Like most chassis, the staggered fitment options are very straight forward for the 5th and 6th gen Camaro's. True rotatable 9.5" and 10" square fitments are also easy to knock out, as they do not pose a threat to the front struts or outer fenders as long as the right offsets are used. With that said, our mission is to solve the communities real pain points - more specifically where the current market offering is failing to meet your needs. We will be performing some in depth test fitments using 10.5" and 11" wheels to get a better understanding of what can and cannot be done. MRC suspension certainly makes things interesting, but all suspension types will be accounted for during the testing process.

There has also been a lot of talk about negative camber, and the different methods of dialing it in. As many of you know, we have an extensive background with the BMW community where adjustable camber plates are viewed as one of the best modifications for the dollar. Camber plates pay for themselves in the form of tire consistency and longevity, and I think we all know the integral role camber plays in proper chassis setup. Although BMW enthusiasts with various chassis can achieve a limited range of negative camber resorting to tricks like pulling alignment pins or swapping top hats from side to side, these aren't real viable solutions for track or race cars.

It is nice to know that the Camaro suspension offers a decent range of camber from the factory, and I believe this is perfect for enthusiasts enjoying their car on the street or for the occasional spirited canyon run. Adjustments made at the knuckle are really not advantageous for those looking to prepare a purposeful track or race chassis, where wheel and tire clearance is the collateral damage.

I do not want to derail the thread into a conversation about adjustable camber plates or any specific camber plates currently on the market, but I would like to get a sense of how many enthusiasts currently run aftermarket plates or plan to incorporate them into their build. This question is asked in our survey, but I think it would be beneficial to all if we discuss things in more detail as it has a direct impact on front wheel and tire options and how we can push the boundaries.

Great write up and thank you for listening. I currently run camber plates (Moreno Motorsports) and run NASA Time Trials which is why I'm so interested in a square 10.5" with 305/30 setup. With the plates I know there will be no issues with me being able to get the camber I want with a 10.5" wheel, even if it means running a little spacer. The MMS plates allow for up to 2 degrees of additional camber so if you're shooting for -3 degrees total it really will only take 1 degree at the knuckle which should leave a ton of clearance. You guys are known for your wheels on track, so it would be nice to have that option for those of us that do want a 10.5" wheel up front for track purposes. cheers and thanks!

Thank you Apex for the customer service and the fun photo shoot!

Wheels are the ARC-8s 19x10 ET25 (square setup). Tires are 285/35/19 Michelin

Appreciate you dropping by Doug, it was great to get your beautiful machine into our photo studio

Thanks for you attention to the Forum!

Personally, I am looking for 2 different setups. I will NOT be running any camber plates.

I have a SS 1LE and need:

19” wheel setup for AutoX that will stay AS legal (no more than 7mm from OEM offset and must retain stock width)

And a 19” wheel that will allow me to run NT01s, G3Rs, R888 or other R-comp Tire for Track days. If you can get a 10.5”/11.5 setup that will allow me to clear 295/305 and 315/325, so much the better.

[Eric SS]

I just went out and adjusted my camber to about -3° (2 at knuckle, 1 at plate) and you can see how much tuck it still has with your 19x10 et25 and a 5mm spacer (effective et20). When I run a straight edge from the bottom of the tire to the wheel well arch there is still about a 1/2” gap between the tire and straight edge.
(Sorry if the pic is large)

Gap with straight edge from bottom of tire to fender above tire. Plenty of room to work with.

Noted and appreciate your feedback. The 19x10" ET20/ET23 and 19x11" ET43 we are planning to produce will keep you within the rules of that class.

For the more aggressive staggered fitment, we are debating between a 10.5" front / 11.5" rear versus a ZL1 1LE inspired 11" front / 12" rear. The 10.5"/11.5" fitment would accommodate the majority of tires the community wants to run - still providing enough sidewall support, and would be a bit easier to fit up front.

The ZL1 1LE inspired 11"/12" fitment looks nice on paper, but test fitments will need to take place on an SS equipped with adjustable camber plates to validate whether this is really a feasible solution or not.

Great info, and thank you for supplying pictures. For the Camaro specific 19x10" wheel, we are thinking of reducing the ET25 (from the BMW wheel) to ET23 or ET20. This should help with strut clearance up front, and for those running them in a square configuration, the rear will still fit properly in relation to the fenders.

Not sure if you are planning to produce both +20 AND +23 fitmnets (and if so this is a moot point), but it seems to me that a +20 would work well on both the Gen 5 and Gen 6, where as the +23 would most likely require spacers or camber plates for aggressive negative camber on the Gen 6 cars. In the survey, I stated I would not run camber plates as I only am able to participate in 2 or 3 events a year. I'm currently running PS-7's, 19x10 +25 all the way around because that's all that was available (and they came from my Gen 5). Without the 5 mm spacer, I can barely get to -1 on this car. Mine is not a 1LE (but does have MRC) so my stock wheels wouldnt carry a 285 tire on the front.

[Dads1le]

My car is a 17 ss1le that has been modified with over 500 Rwhp and 500 ft lbs tq. I’m running in the camc class which allows 200 tread wear tires I will be running camber plates once they are deemed reliable
The ideal choice for my setup would be an 18x10.5 front to run BFg rival 315/30. The rears would be 18x12 to run 335/30
My second choice would be to run a 19 inch setup with 305/30/19 Bridgestone re71 in front and back. So a 19 x10.5 front and 19x11.5 rear
With my specific application there is really only one tire choice for an 18 inch and 19 inch setup but I would much rather have the 18 inch for the additional tire width in the back. With either setup I feel as though I would have several tire choices if I wanted to do road course or switch to slicks
I will have no problem doing some light grinding to help with fitment
It’s really outstanding that your company is reaching out to help make the best overall product for this market!!

I vote for the 10.5 front/11.5 rear on the more aggressive fitment.

Thanks

It was my pleasure

I think, like others mentioned, 19x10.5" and 19x11.5" would be great size for more aggressive/track setup for both Gen 5 and Gen 6 owners. It would also allow people to run say 305 SQ or 315 SQ tires all around. Being able to swap the front tires with the rear at the tire shop after 3-4 events is also an option to be able to run SQ setup but on staggered wheels like Z28 that came with 305's all around from factory.Having options are always nice

Thanks for the heads up, they were still working for me. I think they should be fixed now?

Sorry if I missed it but do you have photos of this setup on the ground?

No, we're in the off-season currently so I haven't ordered tires yet.
