You will be stuck with 8.5" wheels and 245-width tires whether you get the 18" or 20" wheels, and you'll be stuck with the softest suspension (I don't think the lowering package is allowed in Street class, but I'm not 100% sure). It will be a very competent car - it just won't be a winner if anyone of equal driving ability shows up in an SS, Mustang GT, or especially an E90 M3. Its more likely than not, too, that the SS 1LE will end up in FS next year too. So that will put all lower Camaro trims out of the running. For just autocross duty, you don't need the performance exhaust or oil cooler, and you really don't need the brake upgrades either. They won't hurt anything, of course, but they won't help you autocross either.

So in another thread, it was made clear that currently all V6 Camaros are not being produced at all. Are you sure you can find a new one? If not, it might make sense to look for a slightly used 2021 V6 1LE. That car would be significantly better for autocrossing and it's in the same class.

I am running a RS V6 in FS. Tire width is open, whatever can fit on the stock width wheel and fit under the fenders. You are also allowed to go up or down 1" in Dia, but have to keep the stock width. 200 Treadwear tires are the lowest treadwear rating you can use. I know you can change a swaybar, I am looking for what is the best for the Camaro. You are also allowed to change the shocks in stay in FS.

Any tips-suggestions to improve the handling and still stay in class would be greatly appricated. Starting with Front Roll Bar.

I just thought of a possible option for Hunter's Run. I just remembered this allowance in the opening part of Section 13 (Street Category Rules) in the SCCA rulebook:

Both the regular V6 and the V6 1LE are in F Street, so Hunter's Run could put the full V6 1LE parts package onto his RS and take full advantage of the following upgrades: FE3 suspension from the Camaro SS, 8.5/9.5 wheels front and rear, Brembo 4-piston front brake calipers, mechanical limited-slip differential with a 3.27:1 ratio, track-cooling package, suede steering wheel, short-throw shifter, dual-mode exhaust, Camaro SS fuel system to accommodate higher-load cornering, and a high flow front grille.

The biggest advantage is that you could run 245/35/19 front tires and 275/30/19 rears. That gets you a sizeable increase in rear tire footprint, which you can then balance out with one swaybar (if necessary). The FE3 spring and swaybar package from the V6 1LE is stiffer and probably a bit lower, which is helpful. Those are the easy and helpful parts.

Hopefully your car already has the same LSD and 3.27 gear ratio. You don't need the dual-mode exhaust, because exhaust is free in Street class after the cat. You wouldn't have to swap steering wheels because alternate steering wheels are allowed. I think you can skip the different grill under 13.2.A, since it isn't a performance improvement either way (for autocross use).

The harder parts might be the track-cooling package (not sure what all that includes, short-throw shifter, Camaro SS fuel system to accommodate higher-load cornering, and the 4-piston Brembos. It just depends on how hard/expensive those parts are to buy and how hard they are to install. Honestly you could get away without the fuel system - nobody would ever know or care because it's not to your benefit to leave it out. And if someone protested you for not having the short-throw shifter, you should slash their tires. The extra cooling stuff could legit be protested if you didn't have it, because it adds weight. The Brembos could be reasonably protested for the same reason, but at least upgrading to those is cool.

If I owned your car, I'd definitely look into this upgrade...seriously. It would make a real difference in the speed potential of your car for autocross work, and it would be a little more fun to drive fast too (less pitching and flopping around). I'd still try to find a good set of adjustable shocks, and definitely do the alignment. And you can still consider one larger sway bar, if you decide the balance with the two FE3 bars needs some tuning.

Autosenses, there's a chance this could be a useful upgrade path for you, too, if there's any chance you want to stay legal for Street classes in SCCA. And this is especially so if you can order/buy your V6 with the Brembos and oil cooler package: that might knock out two of the harder upgrades to do. Otherwise, you can still go considerably faster with the more extreme mods I recommended to you in post #6.

Thanks for the input. Yes, I know the 1le on both the LT and SS very well. The LT V6 1LE comes with so much hardware it would be impossible to upgrade/replicate it. The Rear diff on the LT V6 is just a basic Limited Slip. On the 1LE, it's the Diff from the SS including the cooling.
