That's always a hard compromise there with a single-pad for multiple duty option on something w/o going exotic and costly... (or noisy as hell on the street)

I didn't see the tabs for the track vents installed. Doesn't the 1LE have the same track vents the SS have and have to be put on or are they installed and just left on? I didn't notice them hanging under the car.

Yeah, I dunno about the vents. I would think they would have used them if they were available....They are a stock SS item....Unless the larger rotors make them unuseable....????...Not sure....

This must really sting for anybody who shelled out $75,000 sticker for the 2015 Z/28. The 2016 1LE is as fast or faster for 60% of the price. This really shows what's possible when you get an opportunity to re-engineer a car from the ground up versus throw a ton of additional parts and money onto an original design that just wasn't as capable.

The reason I ask is, when they've done the SS before, you can see the vents on, but they left the two tire air dams on as well -- you're supposed to take them off.

I've not seen too many low or under car pics of 1LE in final form to know how they did the track vents.. and, if it's an option on the SS models, I'm just curious what they did with it.. Previously, you weren't supposed to leave them in or the smaller backing plate on due to debris interaction and weather exposure. It's entirely possible they changed the vents up enough that they go on at the factory and stay on. I just don't know if anyone ever confirmed that.. We've seen some of the ZL1 venting -- but, I don't remember too much on how the 1LE was set up.

I've noticed a difference on a track with them off, so they do work. I'm just curious if that was a contributing issue or if the pads really did get hot (or if the brake fluid was just starting to get over temp) -- if it was just the brake fluid, that's a non-issue and easy to deal with thing. Pads getting hot takes more money and time to swap.

One driver on one track. I'm sure there are tracks where the extra grip, braking and power of the z28 will make a larger difference.

Many of the tires known for being at the top are being matched by newer lower cost models being introduced. Technology and materials advance, tires a few years old become yesterdays news.
I doubt if you would see much improvement in lap times.
Let's not become fanboys and make excuses how we could've, would've should've.

Back in this post I listed the different tires in different categories.

The Goodyear Supercar's are not in the same tire class as Cup 2's, which is why they aren't going to give the same grip level.

Your logic is unsound and akin to saying a Hoosier R6 is slower than a Goodyear Supercar, because new tires must have more grip. It obviously doesn't work that way. If you spend as much time at the track as some of us, then you'll find out over time which tires grip better. While street tires have gotten much better over the years, they're still not track tires, hence the terminology and the categories.

All of that is a sidebar to the topic here; how the cars lap "out of the box", and that includes the tires as part of the package. Swap out the stock Goodyears for Hoosier R7's and [assuming you can drive] of course you'll shave several seconds off the lap time.

You point is proven with the C&D Lightning Lap at VIR, a track that highlights power and brakes. The 5g Z/28 is much quicker there than the 6g 1LE.

Also note the Audi R8 V10 Plus is slower at VIR than the 1LE, but much quicker at Laguna Seca. Different pecking order for different tracks.

It doesn't need a "better transmission". Even a rear gear swap (few hundred bucks) will do that. But, it depends on what tracks you run if you'd wanna do that in the first place...

It's most likely the fluid too, anybody who tracks ANY car would do a DOT 4 upgrade. In some cases, you have too. Or a simple pad swap...easy fix there. It's not like it effected the lap time.

the flat power curve barely benefits from short gearing.

[motorhead]

Run twenty laps in a gen6 1LE and twenty in a gen5 Z/28. Bet the outcome would be very different.

Either way, that is a very impressive run. Blows the doors off my ZL1.

The 1LE beat the Z/28 on one track. The Z/28 still smoked it at VIR.

Also pro (LS) vs amateur (VIR) drivers...

VIR does not highlight power. Take a look at how the 5th gen Mustang V6 PP spanked it's base GT sibling...all the while dealing with a speed limiter. Or take a look at how the new 1LE V6 ridiculously close to a new GT PP (which has 6 pots and 100 more HP). VIR is a demanding track that shows major differences in handling but probably has on average higher cornering speeds than LS. That's probably where the differences are in the 5th gen Z/28. Another thing to consider is RP is a pro, the C&D guys do not drive to that level. It may come down to the CCBs on the last LL gave them more confidence to drive it faster.
