What Makes the C8 Corvette Z51 Package Worth Buying 

Just curious, how long was your wait from order to delivery? Glad you're liking the car. It's cool that Corvettes continue to provide world-class performance at a fraction of the cost of their competition.

@@Grassrootsmotorsports ordered it last July 6th got it May 25th. Almost a year wait.

After doing all of the normal research on the 911 S and the c8, I ordered a c8 z51 (with mag ride) two months ago. This video and your comment are why I finally pulled the trigger. So, it's all on you, if my wife doesn't like the car. 😁 Take care and thanks

Wise advice

Thanks for advice had a tough time deciding this but a vette mechanic told me no only for track I listened to him

Dealer installed mine during the PDI. I had them take them off before I accepted the car.

Thanks for the wise advice before I order, you deserve a beer from me on the house

@davie crocket No problem 😊 Have Fun 🙆🏾

Who actually recommended the tire pressure to be lowered to 24 F & 25 R for track use? What is the factory recommended tire pressure? Lowering the tire pressure by 1 PSI won't really affect the tire contact patch at all but will cause the tire temerature to go higher relative to the higher pressure setting.

Glad you liked it!

Glad you enjoyed it

Thanks! Glad you enjoyed this one.

Thanks, more C8 Corvette content is on the way.

I don't think that it's not necessarily that it's not recommended if not tracking, the point is why pay $6000+ for a package that you'll never use to it's potential. I've had people reply to me that if for no other reason, you should buy the Z51 for resale value. I say, buy the car for what YOU intend to do with it and NOT for what the next person may or may not want. A nice clean Corvette will sell whether it has Z51or not.

Take a look at this car - engineered for both track and street. No suspension options needed! This is how a world class company does it!!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tpPkrhsKeXg.html

For me I got the Z51 and went with a lower interior option. I buy Corvettes for the performance not for the bling or status. For me if your going to drive a performance car you want every performance option you can get. There are multiple upgrades in the Z51 option that makes it worth getting even if your not going to track the car.

They aren’t building non z51 packages at the moment, if you want one have to have it

When we tested the base model C8 I was a little surprised how quickly the brakes became overwhelmed by heat. They felt great in hard applications at ambient temps, but a few hard stops were more than enough to really create a lot of heat soak.

@@Grassrootsmotorsports And you said slotted rotors are worthless!!! Make up your mind! Look at how Lamborghini engineering solved the problem with both brake rotor material and direct venting cooling the rotors!!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tpPkrhsKeXg.html

The standard C8 Stingray have solid brake rotors that will get heat soaked pretty fast. It may look good but it certainly will not perform!!!

Slotted rotors can lead to premature cracking with a lot of abuse, and the small benefit is probably not worth the reduced service life or the sheer amount of complaints that dealer service departments would have to deal with.

@@Grassrootsmotorsports Negative. I run expensive aftermarket slotted rotors on my sports sedan right now and have never had a problem. This goes to the quality of product, how it was engineered and manufactured. Can any rotor that is made like junk fail - absolutely. However, properly manufactured slotted rotors do not crack even abused. Slotted rotors are used in professional motorsports and you don't think those rotors turn cherry red in the heat cycles? Ever watch viedos of 24 hrs of Le Mans when the cars run at night - what color are those rotors? The problem GM has is they cut corners and make a mid-engine car that is already 10 years behind everyone else when they introduced it!!! GM started with a clean sheet of paper and this is the best they could come up with? I'm not here to bash GM and I want them to succeed and compete on the international stage with the best of the best. But unfortunately, they can't. I can go on but will let you search RU-vid for all the unforced mistakes GM made on the C8 Stingray posted by owners and many of these mistakes has nothing to do with the C8!! Take a look at a manufacturer that knows how to make a product and what it looks like: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tpPkrhsKeXg.html

@@LWRC I don't disagree with any of your points, but how often do you check your rotors for cracks? Before and after every track day? Even during sometimes? And how much are your rotors vs. a solid rotor that's equally as good at shedding heat. The C8Z, despite extremely good performance out of the box, is still built to a price point and a level of user interaction that is as low as possible besides fueling and driving. I have no issues with those pieces being made available through dealer or approved supplier networks, but as equipped parts on a high-performance but still readily available car, I just don't think it's worth the hassle for Chevy. As much as I'd like to see it, they'd lose more sales making the car more maintenance intensive than keeping it more idiot proof.

@@Grassrootsmotorsports Again, the slotted rotors will be much better at shedding heat than solid rotors. The slotted rotors are a two piece design and thus gives more ability to transfer heat. I don't check them that often since they have never ever failed. If GM thinks buyers won't abuse the solid rotors, they are dreaming!!!

@@Grassrootsmotorsports Porsche 911 Turbo can be ordered with either drilled steel rotors or carbon ceramic (Porsche Carbon Ceramic Brake) PCCB rotors. The drilled steel rotors have the holes cast into the rotor blanks before they're machined and drilled - a very expensive process. Owners track these cars all the time. They don't fail prematurely because Porsche engineered them to take the abuse! If Porsche can do that, why can't GM build the C8 with slotted rotors which are easier to manufacture and less susceptible to cracks?!!! Because GM decided to cheap out on these elements and thus makes owning a car at the 6 figure range so frustrating and less than satisfying. I will never own one of these but I give GM credit for trying!!!

In the C5 and C6 Corvette, that plate covered the tunnel above the exhaust that housed the torque tube. The large number of fasteners was due to engineers wanting to retain the stiffness of an enclosed, box-section frame member while providing accessibility to remove the torque tube. To be fair, I'm not exactly sure what lives in this cavity in the C8, but I imagine it's a combination of electrical, hydraulic and coolant lines linking the front of the car with the rear. Rather than re-engineer a solution to covering that inverted valley, GM could simply evolve the previous method of a fastener-rich panel that added stiffness while still allowing access. And ducting rain water onto the rotors seems like a good way to add passive water cooled brakes :)

@@Grassrootsmotorsports As a former engineering major, I call BS. With the right design, all those bolts are not necessary. Only ONE holds the lower control arm on. Think about that. There are probably TWO for the motor mounts. Only 5 for each wheel. It's a COVER! It should slide in and fit into a notch. No more than 4-6 bolts should be needed. NO. Cold water spraying on HOT rotors will make them warp real quick. It WILL sell more rotors which is the end goal. Like I said, this is mostly a track car. It will be a very expensive daily driver despite the seemingly low initial price.

@@MOAB-UT This is what happens when non-engineers try to pretend they understand engineering! While a box-section frame member can provide some rigidity, there are a lot of variables and unless you have access the the design data, everything is just speculation based on what he said and what your reply was - both are speculations! Why are you a 'former' engineering major? Did you not fininsh and get your degree?!!

@@LWRC Haha- thanks for the chuckle LWRC. I appreciate your cynicism. I remember when I had my first beer too. Are you an Engineer or did you even attend college? What design data do I need? Water forced onto rotor equals a bad design for an everyday driver who will be driving in rain- period. That is why you do not see it much on "everyday drivers...." Your reading comprehension skills might be challenged because in my post, I clearly stated: "AS A MAIN CAR, I would pass." I stand behind every letter of every word I stated above. To answer your specific question, I enjoyed every minute of my engineering education, with the exception of concentrated summer session of both Physics and Calc. I ultimately decided to pivot to business. I am very much a people person and found I enjoy more of the day to day engagement that business can afford. A lifetime later, yes, you can read into that to (I am getting old), I have zero regrets. I have friends and family who are engineers and I earn about 3x more than all but one of them who bills out at $275.00/hr.

@@MOAB-UT Again, you have no clue and are just guessing and standing by your guesses are fine. Torsional rigidity has many elements that contributes to it. Unless you know what GM did, and none of us do, just taking wild ass guesses doesn't make it right! And I said nothing about water forced into brake rotors! Regardless, if it was engeneered properly, it can be used as a daily driver. It can be even with the brake ducts directing air / water towards the brake rotors!!! Have you ever thought of how much rain water actually do reach the rotors when they're turning at speed? This is not the same as dropping a hot rotor into a tank of cold water! No, there is no issue with my reading but there is a lack of understanding on your part and that's understandable for someone who couldn't finish the engineering degree. And Physics and Calculus are some of the easiest courses!

GM cutting corners hoping customers won't notice!!! This is how a true supercar is made: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tpPkrhsKeXg.html

Your both wrong I actually own a C8 HTC Z51 and the car brakes phenomenal and that’s after comparing it to the braking on my C7 Z06 and C5 Z06.

@@craigthescott5074 you are not understanding

@@LWRC @stevebeaubien Yeah, you can say GM is "cutting corners" compared to the Huracán Tecnica, but you could buy TWO Z06s for the price of the Lambo.

@@keavenbailey771 Here is the stupidity - GM could have done the design similar to the Huracan! The design they got was done with paper and pencil! The same is true for the Lamborghini! It cost nothing! But GM still F ed up! Anyone who can afford a Tecnica would buy that car instead of the Z06 and not the other way around! Do you find owners of the Tecnica post on RU-vid problems they have with their cars that are not even related to that particular model??!! Search C8 Z06 and see what you find!!! The C8 is GM's flagship car and this is all they could do??!!! There is a reason why GM cannot build a car at the same level, or even higher, than Lamborghini and charge higher prices for it - it's because they can't! • Search RU-vid on Lamborghini's into for the Technica - thus is how it's done by pros who know what they're doing! • Lamborghini is owned by Audi under the Volkswagen corporate group. Audi has won how many top class championships at the 24 hrs. of Le Mwns? How many has GM won the top class??!!! Zero! Chevy has won lower classes but never the top class! • Sheer performance is one thing - there are stock motorcycles that can out perform any Z06 or ZR1! People don't buy moonshine because it has higher alcholic content vs fine vintage wine!
