Tires, weight differences and weight balance does go a long way. Just take a look at the Hellcat's times on Streets of Willow (an extreme example granted since it was slower than a Scat Pack).

I fully agree. I think everyone in here is just severely let down that the ZL1 didn't absolutely demolish the GT350R given it's horsepower and torque advantage.

Agreed, I'm not one. To me to post times so close is a credit to both. It shows how good on track the GT350R is to work over a higher HP car which is no slouch at all in handling. But at the same time shows how you can have that level of track performance but still be a comfy car loaded with features for everyday driving.

IMO it's a tale of 2 car buyers, the R the purpose built track day car (let's pretend those monsters who just keep them in climate controlled garage all their life don't exist lol).....the ZL1 the jack of all trades for the guy who can't have a dedicated toy for the track, strip, weekend, etc...

So this now begs the question.....is the ZL1 1LE going to be running all over the Z06?

I wasn't. As stated, tires and course will play a bigger difference then all out HP.

Seriously, I think Randy was playing for the camera like he does a lot. Remember the ZL1 episode driving the A10. He was making fun of it, saying "it's all automatic".

I think if there was a different driver, no camera, not getting paid for a tv show, things would be different. One time around the track does not a pattern make.

And the Sport Cup 2 tires do make a difference. Just like the Trofeo R's did on the Z28 compared to the Mustang on that day. Sticky tires make up for a lot. Like in drag racing. Kinda a no brainer.

Just my 2.4531234 cents

Interesting question indeed!

You mean the tires that allow the ZL1 to pull 1.07 later G's aren't enough?

Holy fu#%. You mean Randy Pobst tanked on purpose?

So now you want a different driver to validate what a professional already laid down?

And again, the lateral G's the ZL1 is able to pull is outstanding. I've heard nothing but good with the Goodyear Eagle F1 Supercar 3 tires...which may very well be close in performance to the michelin sc2.

Also, the tires on the ZL1 are pretty aggressive and bespoke for the ZL1, aren't they comparable to sport cup 2's? I think it's the wheels that take the GT350R over the top, the unsprung weight difference is incredible. Perhaps with some OZ superleggeras for the ZL1 could get some of that lightweight feel.

Does anyone know for a fact whether the ZL-1LE 19" wheels will be useable on the ZL1 (read somewhere something about the magneride suspension not allowing it...)

Probably Mustang Fanboy was working at the track that day to make sure the GT350R had 2 gallons of gas and the ZL1 had a full tank

Lateral G isn't all tire, even the Hellcat can pull 0.94g on it's crappy undersized stockers. But just looking at the specs on tirerack, 220 vs 180 treadwear is a big clue to which one is stickier. Also the Cup2s specifically state avoid wet/standing water. So think it's pretty straight forward the Cup2s are better than the GYs. How much?....I'll leave that to people with experience with both.

I'm fine with this outcome. The ZL1 is faster, but they liked the 350R more. So what?

No, I am just saying that if anyone runs the track three times, the will get 3 different times that's all.

Plus, you know what actors say like Randy and all the other guys on MT, that cameras add 10 pounds. So no wonder the ZL1 was slow....

Little pixies might have rubbed Vaseline on those ZL1 stock goodyears.

Chassis plays a huge role, but you aren’t pulling 1.07 G’s with a shitty tire.

You do realize treadwear rating is only valid when compared to the same manufacturer don’t you? It’s entirely possible for a 220 treadwear from manufacturer A to wear quicker than a 180 treadwear from manufacturer B.

Until we really know more about how the goodyears compare, I think it should be left off of the excuse list. My guess is, they are far closer in performance than you think.

I’m good with that. The ZL1 is most likely easier for you and I to drive at its limits, and more likely the more comfortable daily driver.

I don't know, I'm just not buying it. I think what it really comes down to is, these cars around most tracks are going to be very close.

Shit, I pulled over 1.0G on my SS sedan with the much hated Bridgestone. Pulling over a G in the turns doesn't mean a tire is good.

Is this not similar to the moral victory everyone was claiming when the SS 1LE was lapping fairly close to the GT350R in some instances?

Choose your poison. More horsepower or, carbon fiber wheels, PS2 tires, no back seat etc...
