Lol it's real life

Lol the graphics are amazing 😏

Sleeping or below average I think. It was only the first green lap but sloppy lines then the point by at the end of the straight was odd (wrong side).

C8 can hit 155 at Road Atlanta back straight.

Sure - where can I email it to you

Thanks. Preparation included: Getting the transmission oil topped up per Chevy instructions, track alignment per Chevy instructions, Carbotech brake pads (XP12 for on track, which I swap back to 1521's for low dust street use - I don't get surface layer issues swapping back and forth. Had this issue before when swapping brands). The car goes great on the standard Michelin PS4's. I'm amazed at the performance and durability on track. I'll be replacing with Pilot Sport Cup 2's though for the coming season.

HPDE is high performance drivers education. 3 is the level. some groups/clubs doing by numbers, letters, or colors, indicating skill level.

It helps. You are probably also becoming a better driver too. Don't credit everything to the car.

@@mattevans2003 Your too kind ! Thanks

@@mattevans2003 One more thing , I have been going with Chin Track Days HPED - these guys a a step above 3 hrs run time and they go to many great tracks .

I'm sold on doing the track alignment but you may not value it for various reasons. The reason I go for the track alignment is partly because of the learning experience i had with my 2016 Camaro SS. I drove this with and without track alignment and kept pushing as I gained experience. I came out of that with a better appreciation of what the tire footprint is doing and how the vehicle dynamics change. I realize the dynamics of the Corvette are somewhat different but the same concepts apply. So from the beginning I was confident that the track alignment would give me more performance and that I would detect and decide if it was too much camber or not. After 10 track days I feel it is right for me. In contrast to this, a person with less or no track time might not actually find any value at all. I would save the cost of the alignment, get some experience and change it after doing enough to get into intermediate group. The main reason is that there is so much to learn before camber becomes a concern. I didn't find the Corvette suffering from understeer on the road like several journalists talked about, so I'm sure it will do just fine on the track without the track alignment, up to a point. The chevrolet dealer near me quoted a lot to get a track alignment so I took it to a shop that does track set ups and they found that it is a difficult and time consuming job to do the alignment. I'll need to look it up but from memory it was about $400 and they should have probably charged more.

@@mattevans2003 : It's time to get the alignment for me . I run intermediate in 3 different groups SCDA , NASA, ERMA . I know this will help shave a few seconds out of a lap . The problem I am having is finding a shop that can do it ? seems like they will need a couple of tools - a digital angle adapter & alignment adapter mounting pins . I do understand it's easily a 400.00 job if not more . Did you get your done in NC ?

Your excessive front tire wear is likely from not enough negative camber. I too have a 2020 C8 Z51 with Cup 2s and Hawk DCT60s and my best at WGI is 2:10.3 . You'll need negative 3.5 camber in the front (this exceeds the factory spec because the Cup 2 is stickier) in the front and negative 2 in the rear. Your front toe should be 0.10 degree positive (toe-in, NOT TOE-OUT). The rear caster needs to be adjusted to 0 degrees. All the best! Joe

For the most part this is true. It is amazing at enabling drive out of a corner. Do this on a track where you know your corner exits are going to forgive you and you can learn how it behaves. There are still some circumstances where your path and speed could go past the point where stability management has enough grip to handle it though. For instance if the grip reduces quickly and you are already starting to excessively rotate then differential braking may not be able to pull things back into line. At NJMP my tires were overheated and I had a four wheel drift at the apex of the corner coming onto the pit straight. I applied a significant amount of power expecting to still pick up good drive. Instead the rear drifted out more even as PTM was trying to help.... The result required my steering correction and it wasn't elegant but together the car and I handled it.

@@mattevans2003 Awesome thanks for the helpful reply. So definitley don't do it on street? Will be dangerous huh especially I just got the car and don't get all the physics yet. Even when I do still don't do it? I don't think I can afford to do track days so I might never find out the PTM thing.......another question, when PTM is working, does it make the same machine gun noise like in C7 Z06?

@@okaythen001 Try it in a controlled environment - A parking lot would do, preferably when it's wet. On a slippery skid pad like environment you can invoke the interventions and learn more. Try different modes to compare what the car does. The challenge with experimenting on the street is that normally the car has a lot of grip and inducing the PTM actions is only going to happen at some very stupid speeds. I think many people will get overloaded with other problems even before you can sense and learn from what the traction management is doing. i.e. narrow lanes, uneven road surface, potential for vehicles/people/animals to be in your path unexpectedly. PTM is not going to save you from all the challenges you may run into but it will hopefully help. The machine gun noise you refer to sounds like rev limiter rather than PTM. When the power is reduced for PTM purposes it doesn't do that and that sound certainly wouldn't come from PTM brake applications.

Oh and if you can get to the Corvette Owners School in Nevada it is really going to help with learning more about these functions even if you only ever drive on the street.

@@mattevans2003 Awesome thanks A lot for that

Originally I thought that might be a good idea (prior to setting it up with the Chevy track camber). After doing a few track days at different tracks (with the recommended camber), I found it performed well and I believe the concern about inside edge tire wear is not that big a deal for the cycle of road and track driving that I'm doing. I've done about 8000 miles with 4 weekends of track days and the outside edge of the front tires is the first part to wear down. Of course if you aren't doing track days for a long time it's possibly worth going back to standard camber. I'm more likely to continue doing a 6-10 track days or or more per season and a moderate amount of street driving so I doubt I'll change it back. Street driving is using the inside edges at a slow rate of wear and just helps equalize out the tread wear. People exaggerate how bad it could be for wearing inside edges, but that means they probably aren't aggressively using the tires on a track - track use is far more significant tread wear. If there was less camber it may work well enough but based on my experience it looks like it could have a higher rate of tread wear at the outside edges with less camber... so potentially less performance and the tires would wear out quicker.

It has the Chevy recommended track alignment. I have found it works great. Very balanced or perhaps a little oversteer depending on my inputs. e.g. trail braking into corners a little late and you can induce some oversteer (but what car doesn't do that...) and very rarely like in this video at the 8min mark I've had the rear slide a bit under hard acceleration out of a slippery corner.

Oh and to add to the insights - My Chevy dealer was over the top on warning that tire wear would be bad with the track alignment then they wanted to charge a lot so I ended up going elsewhere to get the alignment done. For me, with a track day each month or so, the tire wear is still greater on the outside edge of the tires compared to the inside edge. That is to say, if you do enough track time then the track set up is fine. I need to find extra time on the street to wear out the inside and middle of the tires to get my monies worth out of them before replacing.

@@mattevans2003 Thanks. Thinking about getting this done on mine and joining a track club after the blast I had at Ron Fellows, but worried about tires getting chewed up on the street. Though thinking about it, I normally only drive it on twisties out in the country on weekends…so might not be too bad. How many sessions are you getting out of the 4S’s?

@@markw9512 I've done 8 days so far and expect 10. Then they will still be ok for street use for a while. I don't think they get chewed up on the street much, but with the camber at about 3 degrees it simply places all the wear on the inside edges so you need to keep an eye on that. I have a second set of wheels and tires for use on street normally (prettier wheels), so for each track outing I'm swapping and measuring tread depth. Front tires on the outside edges are going to be the first to be used up.

@@mattevans2003 Great info, thanks a lot!! Stay safe out there, watch out for those overbraking types! 😁👍

It's the Personal Data Recorder (PDR) built into Corvettes. Also available in some Camaros. It can be set up with a few overlays. When driving on the street I have it with nothing but the video and it automatically starts - a basic dashcam.

It's a standard part of one of the PDR overlay choices. Either Timing or Track. So go into the PDR stuff via the nav screen then look at the settings available.

Yeah, it's so convenient and really does enable some thinking about how to improve. Key thing I'm focused on at the moment is the braking zone and trail braking into a corner. I realized how much I was tending to charge corners then turn, now I'm trying to finesse those corner entries to achieve better stability and pace.

I've mostly spent time on motorcycles (dirt and road course), but I've done 20 track days in cars now (16 in my Camaro SS and 4 in this C8).

Your needs will vary depending on your previous experience and rate at which the limitations become worth solving. If you haven't done track days at all, keep it simple for the first time as you learn how to handle your car and understand what is going on in a track environment (meaning watching flag stations, handling traffic, using all of the track appropriately etc.). I would just recommend the following first time out: transmission oil top up, fit the brake ducts, and put in higher temperature brake fluid (e.g. Castrol SRF Racing Brake Fluid is excellent). These all mean you can go quickly and you won't be worried about things getting too hot. Next time out: Get brake pads suitable for track use (e.g. I use CarboTech XP12 compound at the moment and this is good for the weight of the car with the std. Michelin 4S tires or Sport Cup 2's.) The original Ferodo pads will get used up quickly but they do perform well. A track pad will last longer and work better when it is hot. I wouldn't worry about the wheel camber adjustment for track until after at least 3-4 days out. It won't help a lot except in certain situations and it is more involved (expensive) to get adjusted than a regular car. Mine is at the Chevy specified track alignment and I think it helps but I also don't think all 3 degrees camber is needed for most corner types. I'm not sure yet - I may reduce the camber a little in future. I had 20 track days experience in my Camaro SS before this car. Similar weight, similar HP and so similar loads on brakes and tires. I decided to replace the standard brake rotors and calipers on all four wheels prior to my first track day. The main reasons are: 1. The red calipers are pretty and I'm going to do a bunch of track days. I'm better off keeping the originals in good shape to put back on when I sell the car. 2. The AP Racing brakes I got enable easier pad changes AND have the same pad shape/size for both front and rear. This means that as the front sets wear faster, I can move them to the rear and get more life overall out of the pads. I keep newer pads on the front since they work hard, and the pad mass mitigates heat build up. 3. The larger rotors and range of pad options will help if I go to slicks later (which I hope too). YOU DON'T NEED TO GO THIS ROUTE for your Corvette to be fast on track. I would say Girodisc front two piece rotors would be a great choice once you have worn out or warped your original rotors.

@@mattevans2003 Thanks for the info. I used to track my Porsche at most of the local tracks here in So Cal, especially Willow Springs Raceway, but it's been years. Initially, I guess I'll add the 2 quarts of DCT, track alignment, perhaps as you mentioned better brake fluid too. Are you running your stock Z51 suspension had it lowered? Thanks for the tips....

@@craigwarner949 My suspension works great standard. It's the mag ride so track mode is firm, without much roll. Standard wheels and tires too at this point. Only significant upgrade is brakes, brake fluid and brake pads.

​@@mattevans2003 Thanks. Keep posting your track videos. The only other person I've seen tracking their C8 is Speed Phenom and he uses GoPro in-car camera. But love your PDR view since it shows much more drivers info such as lap times, MPH, shift points, etc.

+Greg Blanchard Yoshimura full exhaust is the only performance improvement. Other than that, rear sets, sliders and track bodywork.

+HydeMyJekyll Check this later video with overlaid gauges on the same bike at the same track. czcams.com/video/48B_WeICOts/video.html In Turn 5 I do 65-70mph based on GPS measured speed which is less than the indicated speed on the bike (= more like 80mph but I shouldn't be looking at that...). There is a big difference in speedometer verses GPS measured speed due to the diameter of the tire being so much less once the bike is leaned over. Lap times and my lines in July were better with many 1:35s :-) Always learning.

+xisotopex Yep. Not pretty, but no riding on the grass at least :-)
