I lost it in a turn from a stop today. The rear end kicked out at 39 MPH while accelerating. I've previously had a couple of other experiences like that. I have the stock tires on my 2024 Stingray with 27,000 miles on the ODO.

I know the rear engined cars are known for letting go suddenly, anybody else see what MPH they were experiencing loss of rear wheel traction on a 90-degree turn.

 

No, and I track my car.... perhaps there was sand or some other debris on the road. Normal driver settings? Traction control and stability control on?

 

When you say stock tires are you referring to the summer tires? They lose grip under 45 degrees and I see you are in Florida and know it's been chilly down there the last couple of days. Could that have contributed to your problem?

 

27K…are they the original tires? If so maybe they are starting to be too worn…?

 

Really. 27k on performance tires and you are experiencing a loss in traction. Its expected. In addition there is lots to add to the equation as its a 90 degree turn and maybe you gave it Full Throttle.

Performance tires have a soft chili compound on the outer edges of the tire and down through probably almost half of the tread. Then you start going into the harder chili compound as you get down to the bottom layers. Most likely you are around 4/32 to 5/32 tread wear. Also if its cooler as others have said that will make is slicker as the hard compound gets harder and thus no grip. Did the tire indictor say cool tires? I keep this up on the dash at all times.

The fact that you have 27k on the tires is sole proof that you do not drive the car very aggressive or that often. Mostly average driving and maybe a nice get around someone and fun every now and then. The bottom line here is that you probably need a set of tires. If you are at 4/32 or 5/32, do yourself a favor and get another set.

I have owned vettes for a long time and as soon as I get the first unexpected rear end slippage on a nice sunny hot or warm day with my aggressive driving. I just go buy a new set. I get at most about 7k on a set of tires, so you are doing good. New tires are much cheaper than a car wreck. Get yourself a set and be safe out there.

I don't think the OP has Z51 so he doesn't have summer tires. Nor does he have eLSD.

 

Perhaps post a video from the PDR of the event.

 

Doesn't matter. Even with better mileage all season tires and the better cold chilli. The rules are the same as the tire wears. it gets worse. I would bet its time for new tires and an easy check.

 

Could be time for new tires. I didn't go anywhere near full throttle, although I was pushing it through the turn.

Just curious if you guys have experienced any loss of traction in turns. As you can get in a bit of trouble going fast, I like to get my thrills in the turns.

 

Best money would be spent at a performance driving school, and getting some perspective from an instructor.

"Losing it" in a turn, experiencing a loss of traction in a C8 at 39 mph and a few other things would lead me to believe you were not "listening" to the car, reading the conditions accurately or judging what was safe. Getting "a thrill" in a turn gets you in just as much trouble as going fast, sometimes far worse, if conditions are not read correctly.

Get a thrill by evading taxes, not attempting to evade physics.

 

Of the 27k miles on the odo........how many have you put on ?

 

That's happened to me with a lot less miles on the tires. My street leads to a 4 lane commercial road. If I'm going left and it's cold and trafficy and I gas it half way through the turn, it steps out. The car wants to be past apex before you gas it. Or so I learned at Pahrump.

 

accelerating in a turn can lead to mishaps ....driving 101 ...stay turned for more safety tips

 

Did I read correctly? 90 degree turn at 39mph?

 

and giving it hard gas.....what could go wrong ?

 

Couple of things:

• First Tadge Juechter said in a 1 hour interview on Autoline Afterhours when asked about his biggest concern when designing the C8, his words: "I was Deathly Afraid and Paranoid the C8 would have the snap oversteer of my Dad's early Porsche!" Yep I also was concerned that the average driver, if going to fast for a turn, would have the rear end of the 60% rear weight car (like I drove about the time Tadge's Dad had an early Porsche) have snap oversteer. Then the car not driver would be blamed! Folks think Porsche is a great handling car. It is today and give the German engineers credit for controlling oversteer that was an issue with early 911 types. Tadge said it took Porsche several generations to fix the issue and they (GM) had to get it right the 1st time AND DID! He said they did everything possible to have it handle benignly. We had a saying back-in-the-day racing rear engine cars. Better to slide off the road rear first and hit a tree then plow into it in a front engine car! Yep going to fast for a turn with either it will go off the road. With the snap oversteer early rear engine, high rear weight, had to learn how to counter steer as Smoke does when racing his dirt car. Had only a split second to react if someone cut you off your planned line thru an Apex
• Second, tires have a fixed amount of grip. You can use it to accelerate, brake or for lateral acceleration in a turn. Accelerating from a stop and turning (which I do often when driving aggressively) uses some of the fixed available tire grip force to accelerate, reducing the lateral "g" force. It's a vector diagram only have some much grip can use it for acceleration, lateral "g" grip or braking. In fact to get maximum cornering force best to keep some throttle thru an apex or lifting your right foot provides some engine braking reducing max available lateral "g."
• I often lost traction driving my 2014 C7 Z51 aggressively, mostly due to it's somewhat anemic 285 rear tires. When I got my 2017 Grand Sport with 335 rear width tires that never happened on dry pavement. But if slightly wet pavement the rear slid out and the nannies caught it.
• I would never allow my tires to get to 27,000 miles. First sign of one tire tread wear bar showing it's new tires. Mostly for vey wet pavement as one incident of hydroplaning can cost more than 1 set of tires AND NO FUN!

Here are Pics that might help:

With 60% rear weigh car like early Porsche and what I drove IF someone prevented you from taking your planned line thru an Apex had only a split second to counter steer like Tony Stewart is doing here in this dirt car. Not a common reaction for less skilled drivers. Porsche took several generations to fix the early 911 type issue per Tadge Juechter and they (GM) did everything to make the C8 handle benignly and accomplished neutral handle with the C8.


I have a favorite turn I take on the way back from town, in a safe area, (no homes, people and usually no other cars) where I hit high lateral "g" as here with my 2020 C8 Z51. With my E-Ray having fun accelerating after the Apex sooner that I could with my 2020 C8 or would plow off the road "front first." The E-Ray uses Torque Vectoring applying more power to the outside front drive wheel than inside pulling the car around the corner! Your choice use max tire grip force to accelerate or for max lateral "g” or split but on a sharp turn you won’t have max lateral grip.

Seems like you are driving about 1,000+ miles monthly which is heavy use on the summer run flat Michelins - IF that is what you have.
If you have all seasons there should be several thounds of miles left.
Try to not be agressive when tires are cold...or refresh your tires if they are the summer OE equipment.

 

Evading or avoiding taxes. The former is illegal

 

I remember my first time.
