Interesting, I guess I'll have to keep these in mind for the future. I'm surprised that the Toyo RRs will last that long considering they start with 3.6/32" tread depth and have a treadwear rating of 40 but let us know how it turns out. The NASA TT classification form does list them with the 300 treadwear tires so you could run more horsepower for a given weight if using them compared to other 200tw or lower tires but Hoosier R7 and A7 seem to be the most popular TT tires at NASA events near me. Ken Hill (who seems very knowledgeable) also says Toyo RRs last a long time and I think he also has a graph comparing them to SC3Rs somewhere in this thread: https://www.camaro6.com/forums/showt...9#post11223699. The lap time gap he sees between them and SC3Rs is similar to the one I see between SC3 and SC3R but I'm less experienced than he is.

So far I've been able to get slightly used takeoff sets of SC3 and SC3R tires for well under $1k each so I didn't consider alternatives but I imagine those will stop being available since Camaro production has ended. If 345/30/19 Toyo RRs will fit in the back of the Camaro then I could run them with 295/30/19s up front on my ZLE wheels but I guess it might increase understeer vs. 305F/325R tires that I'm used to.

I messed around and did a 139.89 on Sat. and I'm leaving a little time on the track. I'm convinced that proper rotating/flipping will get at least 3 and probably 4 track weekends out of 1 set of tires.

I went to Mid-Ohio for the first time last year for 2 days and 1:40.8 was my best lap on SC3 tires in mid 80s weather but that was before the repave so idk if it is a fair comparison to your 1:39.89 lap if the track might be faster now but also your hotter weather probably slowed you down more than me. I only get about 3 track weekends on a set of slightly used SC3s starting around 6/32" tread depth plus about 2k miles of street driving but Chin track weekends offer 6 hours of driving vs. maybe 4 hours for some other organizers so I guess track hours would be a more precise way to measure tire life.

I wanted forged wheels for peace of mind while on track so I ended up getting a takeoff set from a wrecked ZLE but I like the Apex 10 spoke design better and the forged versions haven't been outrageously priced during group buys and Black Friday sales. I've bent 2 OEM SS 1LE forged wheels and they were both able to be repaired for about $100 each. 2 of the ZLE wheels were bent when I received them too and they were also repairable. I would have more concern about possible wheel cracking after years of track use and repairs possibly not being doable and/or lasting if the wheels weren't forged.

Some people also like to change sway bar(s) with a square wheel/tire setup to improve the car's handling so you might want to consider that too.
