    A used c8 z51 will be a great grand tourer. I plan to put 100,000 miles on it with no regards to warranty or modifying it beyond maybe bolt ons.

    I can handle doing the repairs on a pushrod in my garage, highly doubt I’d need a lift but even if so I plan to buy a $2-3k used decent one and put it in my garage.

    Mildly surprised at how much faster GT500 is than C8 around Grattan. It's a fast porker. Well, they are both fast porkers.

    Why? The C8 was on its PS4S while the GT500 was on the bespoke "no faster tire" Cup2.. Not even remotely suprising. Also, who was driving the C8? A C&D editor?

    Stock is stock man. Drag radials on the demon are why it can maximize its potential and run 9’s.

    Ford picked a sticky track tire as the top rubber so we can be impressed by lap times.

    Dodge tuned the demon to optimally stick the nittos, ford tuned the gt500 to optimally stock the cup2’s.

    As far as the c8, it’s set up with moderate push so a track like gratten probably is very frustrating. Leguna seca is probably decent, and big willow is probably excellent.

    I think the 2021+ c8’s will slowly pull understeer out and tweak to find breakthroughs. We’ve all seen the comments by the c7 chassis guys saying the new car is less capable in corners, the lap time difference I see from c7 to c8 leads me to think if it weren’t for the dct and 40hp, the c8 would be frustratingly slower than the c7 overall.

    I still want one for the McDonald’s bbq esc Ferrari similarity. No, it’s not great bbq (or a Ferrari) but yes, it’s good enough for the great price.

    Plus, the stock Killer Chiller set-up.
    Plus, the skinnies up front.
    Plus, the actual ram air induction.
    Plus, the tuned PCM.
    Plus,.........lol

    It's just a beast of a car man.

    Great car. I like demons.

    I like the gt500 to. I’m sure to a Bugatti 13c owner, a foxbody mustang is heavy so it’s all relative

    Because it isn’t a small delta.

    No shit stock is stock... I got flamed for saying that earlier about the oem tire on the non CFTP. Yes stock is stock, my point is, its not suprising given the tires. Thats all. 6 seconds is a lot of time, but a sticky tire vs a not so sticky tire is game changing. (I dropped 2.5 seconds going from a 120tw to a 100tw between my last similar R comps).

    You put these on the same tire and that delta really will become small... Or put it against a showroom stock non CFTP.

    I will also add that 6 seconds between the FRPP team vs a who knows who C&D editor is not a large delta.

    But 6 seconds on a 1.x mile track is pretty ridiculous though

    You dont know rediculous until you've seen the differences in real life and just how large they can be, even just different days/same driver. Now factor in a real pro vs a magazine editor and its just not realistic

    STFU and discuss cars rather than turning into another LostM tragedy :D

    Oh driver makes all the difference. I’ve lapped people go cart racing at small indoor tracks so I get it.

    Honey, when you yell at me, it really puts me off. No make up sex this time. I’m going to the man cave.

    All the bickering aside, im curious to see if chevy fixes those dumb ass brakes and how the car does on a real track instead of the awful pos that is Gratten raceway. It wont touch a CFTP car in any test but i really want to see how it stacks up against the regular buyable gt500 in an all things equal scenario

    I think the c8 will shine at smooth naturally banked courses like leguna seca but be frustrating at flatter and bumpier tracks like grattan.

    When you dial under steer into a car, it doesn’t turn in, it doesn’t slip out, and it plows over bumps from my experience. Beats dying in a fiery tail spin though.

    I think a c8 z51 will struggle to keep up with a 202 gt350, and will be slower than a 2020 gt350r.

    The updates to the gt350/r are quite nice. I think the base gt500 will be faster in track than a gt350r but barely. Power and mainly braking being why, cornering speed being 5-10% lower. Maybe a 1:35.5 at Laguna vs 1:36’s for the gt350r. I hope to see cftp gt500’s sneak into the 1:32’s at Leguna but I’m confident the car has 1:34/ high33’s in it.

    Having done bullshit builds on forza, I hit mid 1:34’s with a nose heavy 4025lbs pig running full aero and sport tires. Factor the better brakes, almost slick tire, better than 55% balance, and hugely the weight not being on the nose but center on the floor, aft the front axle, and the wider front track, the dct shifts etc, I think the car will grip it’s way to very impressive times much like a Tesla p100d handles far better than the 5200lbs curb weight would have you believe.

    I just want the open air, and midship feel. I want to get a better custom speced alignment, lighter wheels/tires and bolt one on the eventual one I get if I go that route. Since I’m a caveman, I could honestly see myself being happier with a c7 grandsport convertible..
