You wouldn't want it on the street. Give me the extra cash from the pooch and I'll soon show you c8 tailights. Turbo and blower kits are out there

for 30k worth of mods you can bump to 900 hp and lots more torq on the base car. This will come soon enough for the c8 z06 as well as it's the same ecm architecture

or wait for gm to do it. It will still come in under the pooch price point. It's flattering but unrealistic to compare cars at such a wide price point gap

If the pooch isn't WAY better, it d@mn well should be!! 400k?? get real. Not exactly a bargain sports car like the vette folks want to compare it to.

I was hanging with the track rats and learning about the GT3s The gent was selling his with relatively few miles. He could get more for it, and with the CF brakes needing replacement, it was the smart thing to do.

I never thought of selling my vette as more cost effective than fixing the brakes! But then his brakes cost more than my vette!!
Have you driven one of the 900hp C8 with the aftermarket clutch discs? How well do they drive since you can’t tune the transmission?

The end result was it was a total flop at the dealerships. So, I could see GM being a little gun shy on a race car package.

They could create an option package that could be special order. I think their concern with that would be the economy of scale in terms of production cost. There is a lot more to a race car than just aero and lighter seats. Now, I guess they could pull the Dodge thing. Dodge is offering the Challenger in a convertible by having your car shipped directly to Drop Top Customs in Fl for the conversion. I suppose that GM could offer a package through a third party like Pratt and Miller or Katech. Or, GM could take another tip from Dodge's Direct Connection, and offer track packages that would be dealer installed and covered under warranty.

But, at the end of the day, 90% of the people that buy these "special" cars like the GT3rs, or the Z06, or whatever 'track' variant, will never, and probably shouldn't ever try the baseline version of these cars at anywhere near its performance limit. These folks are just buying the badge to show and shine and will probably never see triple digit speeds. lol
the Z/28 was a flop because it was a 3850lb joke of a “race car” it had a cheap and extremely dated interior of a car designed many years before and still weighed WAY too much. The carbon ceramics were a “pretend it’s a race car” accoutrement and not what a real track car uses.

now it’s adored by boomer collectors that pretend it’s a fast car.

That's why you can't just put monster engine, fat sticky tires, stuff suspension and solid bushings in a stripped 4000 lb car and expect it to be a massive hit. Also, I'm pretty sure the ZL1 outsold the GT3, GT3RS, and GT4 cars combined for a given generation. You're not going to sell 10,000 stripped down track variants.

And you see this mindset repeated here endlessly as people post lap times as some sort of authority about which car is better and say things like "with the cost difference, I could add a TT kit and it would only ever see my tail lights!" Great- congratulations for turning a road race into a boring drag race.

Heat is a function of power, not torque. AWD doesn't really help. They'd be faster without it. But overall, yes, they can run the same lap times with less power because of "little things" like drag, weight, RWS, and not pulling 200hp of timing lol

Yep. Well power and efficiency. The latter of which is much better with turbo vs supercharging.

So, modern Corvettes "plow through turns and then just drag race on the straight"?
You should actually DRIVE a modern Corvette before making such an asinine and totally untrue statement.

I love how lap times only count when a Porsche is the fastest (Nurburgring). If any other car is faster, then it's a one lap wonder or too much HP (i.e. more than a Porsche).
I guess this theory explains how a 2016 C7 GS is a virtual dead heat with a 2016 GT3RS at Lightning Lap...despite the GS giving up 40 horsepower and weighing 290 pounds MORE than the GT3RS.
So much for the "drag race" theory

First thing that popped in my head when the 2014 Z28 was going to drop was, “did they do anything about the LS7 heads and Ti dust?” No. Also, the weight coming in 300 pounds lighter than a ZL1 sounded impressive, until you read it was still 3700+ pounds. The quarter was covered in the same timeframe and trap speed as 2002-2004 C5 Z06 in 2014.

I appreciated the car for what it was, but I feel like they could’ve gotten more weight out of it somehow. Overall, I think the Z28 makes for a fantastic street car. I see a few around from time to time and wish I could have one. Just wish they would’ve done something different with the LS7 versus using ones from a surplus. I love the LS7, but I’m not going to convince myself pulling valve covers to check valves and sending oil off for analysis to conduct a CSI investigation on the results with the forum every oil change is normal.

I have owned three "late model" Corvettes (a C6 and two C7s), and I have a private track membership. I've tracked "late model" Corvettes plenty, along with everything from Miatas to Porsches to BMW to Ferrari. They understeer, and I'd probably categorize it as moderate even with stage 3 front splitter + 2 rear and wider (315) tires up front. Sure, I could drop the hammer on exit and induce oversteer, but that is very far from the car's natural tendency.

You'd be hard pressed to to find a ~3500lb FE car with tires 50mm narrower up front that didn't understeer.

As far as the C8, I think it's pretty well documented that it understeers. I haven't tracked one of those.

I track my 458, which has 235s up front. Some day I'll get around to weighing it. Plenty fun and lively on the track, though not a track demon to be sure.

Yes it understeers, some of which can be dialed out with camber and toe-in adjustments. I never heard of putting 315s up front, that sounds wayyyy big.

On a widebody C7? That was my track setup. 315F and 335R IIRC.

Some one said that they could simply BOLT-ON a aftermarket C8 TWIN TURBO kit or C8 SUPERCHARGER SYSTEM and attain 900HP and massive torque and SHOW the POOOCH the C8 taillights. Bye Bye poooch.

Typical idiotic bench racing statement ………..the C8 twin turbo will explode on the outlap to the 3rd lap as it will detonate and overheat. Bench racing and drag racing it might win until it breaks once again.Drag racing takes zero skill and is simple.

What about this IMSA FIA race proven state of the art “upside down aircraft” for the street. Try one you will like it! Its brutally real fast and lasts. A IMSA GT3R CUP car for the street.

Made in Flatch Germany and likely be delivered next summer no games no excuses with a 6minute 40s Northcourse ring time.

Andreas Preuninger Porsche race boss GT cars- most complicated GT car ever. Porsche Uber Alles right pierre. Where’s my Z06? Meanwhile GT4RS is being built and will be delivered in 4th quarter 2022. Supply chain delay at Poooch ag advised me that no fancy LED headlights save me $850 .

Here’s a bad-*** Pooochh that will anilihate C8 Twin turbos with 1000hp running 92 octane pump fuel. Poooch 13.5:1 CR 92 octane no problem. My GT3RS will make over 580hp after im done too.

I know you had a C7GS, but I’m confused by your understeer statement. What was your suspension setup and alignment? You stated 50mm narrower fronts, but only ran a 20mm difference. Was that a typo or were you referencing stock? Of course ones driving style can induce understeer, do you have any videos to share by chance?

Note that I did clarify that the Z/28 was a different platform and a different demographic. The point was that GM did a "street legal race car" (at the very least, marketed as such) and it was major fail. Not to say that a Corvette version might not experience the same fate, but I would highly doubt that the take rate on such a car would surpass the 2% mark.

And whats the "take rate" on a GT3? Probably about the same. And regardless of what the take rate is, it elevates the entire Corvette brand with the recognition of the car's blistering lap times and visceral feel (a rising tide lifts all boats). There is no question that the mere existence of the GT3 elevates all other 911 sales.

I ran something between the track and Street/track alignment.

Stock definitely understeered a lot. Obviously, running wider fronts helped, but it still understeered.
