Cups = OEM Cup2 tires. Sorry for ambiguity.
I can't comment on launch. I only did circle track. Cup2 take a lot of time to heat up though. They're also a stiff and thin sidewall. I can't image them hooking up better than an R888/R888R on 18's if for no other reason, sidewall and heat.
The problem with R888/R is how damn big the voids are and how it takes away contact patch. And they're freaking worthless in the rain anyway. I wish Toyo would make the RRR8R in a slick or "cheater slick" like the Cup2's tread pattern.
Look at the freaking pattern. They probably have 1/3 of the contact patch lost for absolutely no reason.

I see what you're saying. I'm just looking for a drag radial that I can drive to/from the track (it's about 120 miles) and is going to give me the best launch when I'm at the track. Hopefully the OP chimes in here.

I'd venture to guess it's not the factory sized Cup 2 due to sidewall.

OP was interested in handling and specifically not a drag radial.

So the NT05R is going to give better launches than either of the Toyos? I was most interested in the additional handling of the Toyos since it is about a 2 hour drive to the track and it's a lot of windy back roads and i like to get there in an expeditious manner

You wanted better launch on a tire you could drive to the track. You didn't say you also wanted to corner aggressively on the way to/from the track. The NT05R will have better straight line grip but won't corner like the two R compound Toyo tires. With the added info, no , the NT05R is not for you or the OP.

So after actually running the R888R's they honestly feel more like a drag radial than a track tire.
They are "mushy" in the corners and hook real good in a straight line.
The Nitto NT01 is a better road course tire in my opinion... which is weird because Toyo and Nitto are the same company.
As heavy as these cars are Im not sure I would want a softer "lateral feel" tire that would be traveled on for any distance.
I actually bought these to try out @ MSR but now Im thinking the Cup2's just became my "track tire" again.
And JonaOhana, I know where the 295's rub now and I'm assuming your nice LG inner intercooler vents are missing a few "teeth" now as mine are..
I'll at least try them once, maybe they do better with more heat which =psi. I'm running 30 cold and they make it up to 34/35 hot on the street and the mushiness is less pronounced at that pressure.
Toyo recommends 32-38psi hot so maybe that's the answer? ...38psi

!haaaaaaaaaaa ha ha ha, my inner intercooler vents practically lost all their teeth, I told you it rubs... I didn't mention the missing teeth because I thought its probably irrelevant to 99.999999% of corvette owners, so funny, Im glad Im not the only one out there who lost the intercooler vent teeth. As for the mushy feel, I start my tires at 33-34. Love the handling at that PSI, no compromise to traction either.
I know someone asked about the 60ft times...
As for the 60ft times, I know nothing of drag racing, Im not sure what 60ft is, Im guessing its the first 60ft on a drag strip ,
what I do know that these can hook with no wheelspin to very little wheel spin, I've never had a better tire for both straight line grip and handling.

Hey Guys,
I've been following this thread since the night it was started and am finally ready to make a purchase on a new set of tires. I'm running a Z51 Stingray that's making 696whp, so I'm looking to get some more grip than the factory tires offer.
I'm 100% street driving, though I may take the car to a single 1/4mi day this year and see what it does.
I need traction but do NOT want to sacrifice handling, as I love my Vette's corning capabilities. ...In fact my front tires are worse than my rear. :p
I was dead set on buying these in 245/30-19 and 315/30-20s, hoping to get 10k miles out of them. Does that seem unrealistic? Do you have better suggestions for my use case?
Thanks!

I got my R888s to run on the road course and to be able to drive 100-400 miles OW to the events and they were fine for that. I plan to use R888Rs the same way. PSS are my DD street tires. I seldom run the car hard on the street, leave that to the various performance events I run.

Finally ran R888R at the track i've been running Cup2
315/30/18 F vs 285/30/20 F
335/30/18 R vs 335/25/20 R
R888R on forged signature wheels.
Despite being wider and on a forged smaller lighter wheel, the R888R couldn't hold a candle to the Cup2. My very best time was a 2:00.2. A lap over 2:00 on the Cup2 was a slow lap. I'd consistently knock off 1:58-1:59 with a few 1:57 on a good cold day.
In fact, times were barely better than they were with OEM sized MPSS. However, the R888R could definitely take more abuse. They wouldn't get greasy like MPSS.
I'm not sure I'd go with them again.

Well when you run a 28 inch rim on the rear, what do you expect???
(obviously i know you meant 18)

Glad you posted. I have the same exact setup but I'm replacing ZP run flats not Cup2's. The price alone for replacement tires were worth it to me, plus the added grip. I'll be interested in hearing how many tack days you get out of these versus the Cup2's. I've never driven on the Cup2's so no way to compare for me, but the R888R's were infinitely better than the ZP's. Honestly if I get 99% of the Cup2 performance, similar track tread life at 1/2 the price.......I'm good.

R888r
I have run the toyo r888s For a few years now, d on all three of my Corvettes
i’ve now recently stepped up to the r888r on the Z.
I’ve got signature wheels, and run 275/35/18 upfront, and 345/30/19 in the rear, awesome street tire and Canyon tire and with a little bit of throttle control beautiful launch on the street… When I go to the road course, I put on perelli scrubs, save the toyos for the street 275/35/18 upfront, and 345/30/19 in the rear, awesome street tire and canyon tire and with a little bit of throttle control beautiful launch on the street… When I go to the road course, I put on really scrubs, save the players in the street, Canyon and runway…
i’ve tried a few different sizes upfront, but the 275/3518 is the one that looked and felt the best, gave the car the balance needed… Luckily the first two sizes I tried my C6 and it needed tires anyway LOL
Posting from my phone so forgive me if it’s a little scattered…
