Viper ACR vs GT2 RS stock to stock on same rubber at Thunder Hill

Cool videos!

I'd love to see what Jeff Cook (driver in this video) can do in the ACR with the Cup2R that are magical on Porsches and the AMG GT Black Series.

At the 5 minute mark in the part 2 video the Cup2 R are 1-1.5 seconds faster than the R7. The Kumhos are .1-.2 seconds faster than the R7. I wonder if the Cup2R are capable of running 1:27s at LS in the ACR.

Yeah those tires are nuts, it's why the GT3 took such a leap in time at the Nurburgring. If they are worth 1.5 seconds over an R7 at Laguna, they'd be 7+ seconds at the 'Ring over R7's.

They're kind of bullshit tires from what I've read. After 3-4 laps at most tracks, they overheat and get greasy. They're hero lap tires.
I'd imagine on something like an ACR with 2-3x the downforce, it wouldnt last long at all.

It would be cool if all spec races went to the same tire (just different sizes) and they became a "benchmark" tire.

I believe they do this with motorcycles, as far as lap comparisons go.

That's nice. Though, motorcycles are probably a lot easier since they all have the same size wheel and, within a class (600, 1000, etc) same size tire.

Correct! Just making a statement haha

I don't care on cars if they're the same size or not, but the same compound would be ideal.

Yeah, I just meant in terms of logistics and availability.

Given the countless size combinations for width, aspect ratio and rim size, it would be near impossible to ever execute. Cars in the Lightning Lap probably range from 17" wheel to 21" wheel, 245 width to 345 width, all kinds of aspect ratios and etc. I doubt any two cars even have the same size tire most years. And on top of that, everyone has a different offset, lug pattern, etc so you couldn't even try to get a few different wheels with different widths (ie: a bunch of 19s).

Stinks that it's so impractical, but it sure would be nice.
