Track wheel recommendations
Just had an issue with an OEM wheel, and the car gets heavy track use, so I think I’m gonna go for some forged wheels. Was thinking of going 18x 9 front and 19 x11 rear. I don’t see the need for much larger tires than stock. Only issue may be clearance of the front brakes. Having big brake kit installed next week. I may be able to save 60lbs in unsprung weight.

BBS has a flawless reputation as well, but I'm not sure if they offer C8 fitment yet. A set of FI-Rs would look great:
The C8-R definitely appears to have BBS fitted:

I'd like to get a set of 18x10 and 18x12 Forgeline to run Pirelli scrubs on. 275/645-18 and 315/680-18 should work. For now though I am cheaping out and buying another set of stock rims on eBay and trying the Goodyear 3R in stock sizes

Goodyear is a unique choice. I was fortunate enough to attend a C7 school with Ron Fellows at Mosport/Canadian Tire Motorsports Park. In between sessions, we chatted about his experience and explained the C5-R was 3 seconds better around Sebring when they switched from Goodyear to Michelin. 3 seconds per lap is an eternity! Pilot Sport Cup 2s are a great option for ride and drive - some run Toyo R888R as well depending on sizing - but that's a bit aggressive for the street, especially if there's any chance of rain.

Why go with larger front tires? Most of the mid engine cars seem to go with narrower fronts. I just had a new set of Cup 2s mounted today, and it seems one wheel isn’t running true, so I believe there will be Forgelines in my future too. They usually have a sale in November, so will probably hold out until then. BTW love your you tube vids and all the work you do using Cosworth data. Last night I finally got around to installing the Pi software following your directions. It’s fun and really is eye opening, when you see how little changes add up to significant time savings.

I don't think we can base anything on racing slicks from 20 years ago. I agree that the Michelin tires they added to the C6 towards the end of the run were light years ahead of the GY Eagle tires of the day. However, I have several friends that have run the 3R on Camaros and by all accounts they are stellar tires. I actually expect them to be slightly better than the non-ZP Cup 2 but we will see.
We deal with the most exceptional performance vehicles on the planet, and I'm not aware of any of them leaving the factory with Goodyears (including domestics). If the argument for purchase is for patriotic ties to country of manufacture, or budget, that's a different story, but the data seems to be clear that Goodyear isn't the fastest way around the track.

Judging by the Michelins pictured in the C8-R picture above, the advantages over alternate manufacturers appear to be just as relevant today as they were 20 years ago.

Have you ran a G3R? I second what Poorsha says, the tire is as fast if not faster than the Cup2 based on others I run with that have them. Don’t know anyone running Cup2Rs, so I’m not comparing those to be clear and saying Goodyear is the ultimate. Pirelli being Italian generally comes on exotics and the Trofeo R is right up there with the other gumballs, but the ZL1 1LE did come from the factory with the GY 3R and it’s a formidable albeit heavy track star. I’m considering trying a set for fun as I can get a discount on them through USAA even though I race on 200tw tires.

But Goodyear has a much much better tire and compared to Michelin and Trofeo it stood it grounds... in this test
But for me, any company that mix politics and company products the way Goodyear did , will loose me as a customer..
Dont care if Goodyear went out and said Biden is best, paid to support him... no problem.
BUT when they deny other political views and threaten to fire people supporting Trump or whoever they target as "not acceptable" zero tolerance .. THEN they crossed a line and do not get to keep me as a customer... even if it is a US company... And Trofeo is Italian and Michelin is French.... They haven't made the same stupid message so I go with them.
Back to topic :-)

Goodyear Eagle F1 SuperSport RS is wayyyy better than G3R so I doubt G3R is anywhere close to a CUP2, based on comparison I also seen between Cup2R and Cup2...

Hadn’t seen that review, thanks for sharing as it was good. It showed the hotter Cup2R and GY F1SSRS with identical lap times, obviously the regular cup2 and 3R are both slower though don’t see how you come to that conclusion. I haven’t seen a back to back comparison between the two on the same vehicle, but basing it off times I’ve seen at local track from well driven C7Z07 and ZL1LE both on OE tires.

Supposed to be 680mm or 26.8” which is 0.7” shorter than you’re 345/35R18, hope that helps.

This is a good site for info on the Pirelli slicks:
https://usedracingtires.com/pages/pi...ick-tire-specs
275/645-18 OD = 25.2"
315/680-18 OD = 26.8"
I am pretty sure this is the only place to get them new in the US and the last set I bought was ~$2700/set.

Is your car the black one that was running the AP kit at Road Atlanta?

Cool - I'm interested to hear how the car handled with the Hoosiers. My car is loose on turn-in on stock tires with the track alignment and it wasn't confidence inspiring.
