07 package worth it?
I do 30+ track days per season. I would use different tires and really don't want ceramics. Does the different suspension really make a difference in lap times? By difference I am asking if you would notice any dramatic difference driving back to back with all other features the same? Could care less about a few seconds as any day I go back to the paddock without scratches on my roof is a win.

If you couldn't care about a "few seconds" definitely don't get the Z07. The suspension alone is probably measured in fractions of a second on most tracks, it's a little stiffer spring rate and shock programming. The Aero -- if you want -- is available with or without the Z07 package.

If I were doing 30+ track days a year and money wasn't a huge deal, I would opt for the Z07 pkg. Resale value will be higher, steering and dampeners will be better set up for sticky tires, properly mounted rear wing and for warranty purposes, if you have an issue and you bought GM's track focused, track package equipped car and had issues ON TRACK, I feel like there would be less pushback from them to repair the car. Maybe not, but it makes sense to me...

Steering calibration is not changed with the Z07 package.
And if he opts for T0F/T0G, he gets the aero from factory.
The bulk of the performance improvement the Z07 provides is the Cup 2 R's.
The non-Z07 is still track covered by GM's warranty unlike the non-Z51 Stingray.

I'd probably do a non-Z07, option the aero but stick with non-CF wheels and do iron brakes. Then buy some track pads for the brakes and a 2nd set of wheels with track tires. Skipping Z07/CCBs would easily pay for track pads, wheels & tires.

Thanks. Issue is not $. Issue is Accelerate Yellow. "available" Z06s with AY not available with 07 package. Some available with aero without 07.
I already have wheels and tires on hand and the CUP R tires do not impress me. Stock Ms on my Porsche GT4 were destroyed in 3 track days and day 3 I quit early.

You do not need the Z07 package if you can get the Aero package without it. The couple of seconds difference between the base and Z07 package come pretty much entirely from the Cup 2R tires (probably like 80%) and aero (probably 20%).
That said, there are plenty of awesome after market aero options (including better looking wings).
It's true that in many situations a Z07 will have higher resell value, but I'm guessing that will be mitigated by track days anyhow.

After tracking 6 Porsche cars, last 2 being 718 GT4 and a 992 GT3, I honestly don’t think you need the aero. I took my Z06 non aero to Laguna Seca and beat my PB by 6 seconds, went from 1:41 down to 1:35 and car has way more to give, I’d guess a 1:30 in it or less. Car is superb, so unless you doing cornering at 130+mph, the aero won’t make much difference, so do as I did, save the money and instead get good rims and tires and maybe AP racing breaks.

I'm not a 'track rat' and the cost was not an issue for me (we are blessed).... Anyway, I drove a friends and thought, this would not be a lot of fun driving to Starbucks or out to dinner. I loved the look until my wife said it would be a 'pain' putting anything in the trunk (shopping or a road trip). End result... we got a '24 Z06 HTC and absolutely love it....

More awesome answers. 07 package appears to be the same as the CEP when buying a Porsche GT car. (Cash Extraction Package). Sorta like the Weissach Package on my 19 GT3 RS. $18K option that saves 12 pounds. The true high performance of these CEPs can give you an edge at cars and coffee.
CCB lower weight and lower dust. Note that the Z06 CCBs are also used in the McLaren 570 cars. If I remember correctly, same part number too except has McLaren where the GM logo would go.
The Z06 aero package can produce 70 pounds? At what crazy speed? Think I read that somewhere. I can take turn one at Club Motorsports at 100 in my GT3 RS, but seldom do because its not a better line. 90 seems best for me.
My tires of choice are Dunlop Max Sport Race and Trofeo Rs. In that order. Dunlops are very durable and can easily handle a full session at full send. Trofeos are a bit sticker but require an extremely smooth touch because they will get greasy if you have too much slip angle. I like Trofeos for the cold parts of the season because once they get greasy your session is done.

734lbs = x * 186^2
x = sqrt(734/(186^2))
x = a very rough downforce coefficient = 0.0212
With this you'd see:
80mph = 136lbs +/- 25lbs
100mph = 212lbs +/- 30lbs
120mph = 305lbs +/- 35lbs
These are actually useful amounts of downforce. You can easily do much better after market though.
This is the total amount of downforce claimed for the car by GM. C7Carbon sells a "Victory" spoiler that generates up to 771lbs of downforce at 160mph all by itself.
Anyway, you definitely do not need the aero package, I was merely stating that for extensive tracking purposes, the aero package is really all you would theoretically want from the Z07 package.
The stock Z06 still produces downforce though (rather than lift), 362lbs@186mph when running the front gurney flap and rear high wickers.

For the OEM, are the rear wickers included? I wanted to get the nicer carbon rear spoiler, but didn't want to pay the ridiculous $3k for it. In the pics it looks taller so I was hoping the standard package one could be setup to look the same (and have the same performance).

No there isnt, plus if you buy sigla’s, you have holes to patch up. Best to get OEM wing from factory. Plus after market parts, car is no longer original. Im glad i waited and got everything from factory.
