Just picked up a 2017 M6 Hellcat with 25k miles. Pretty cold here so traction isn’t the best but should I be spinning the tires at 60 mph in 4th-6th gears? Can’t tell if the clutch is slipping or if I’m actually breaking the tires loose. No other issues with shifting.

Go to 2:45 he talks about slipping

Even on summer tires below 40F when the rubber is rock hard, spinning at 60mph in 6th gear is hard to believe you wouldn’t feel the car sliding as fast as the wheel speed would build compared to actual speed.

Why are you punching it in 6th gear at 60mph? Just curious

Is traction control indicator lighting? If no the clutch is slipping, but I would think you’d smell it???

The clutch on these M6 cats are not a good match at all for the amount of torque this engine puts out even when stock especially with the addition of clutch delay valve. If you smell clutch during a spirited drive your clutch is most likely starting to slip.

Never slipped in 4th, ever. Slipped in 3rd with stock P0AS but at higher speeds. I always know when tires slip, even my wife does.

I went through 4th-6th at varying speeds (45 mph - 70 mph) to see if the effect was similar. Unfortunately, the “spinning” seemed to happen through all 3 gears.

I get the burn with the wife comment 😆 but the backend seemed to kick out a few times so made it harder to differentiate between slipping and spinning.

Just pick one gear, like 5th at 60 mph and foot off the clutch go WOT and if you get any slip or see the tach rpm jump then you need a clutch.

Sounds like clutch to me.

Mine has never broke loose in 4th either.

I haven't worn out a clutch in decades but back in the day when a clutch slipped, it wasn't just a little bit. As soon as slipping started the engine would rev, start putting out more torque and slip a lot more. Pretty unmistakable. Not sure about these new fangled things!

That's the big problem with used manuals, everybody thinks they know how to drive one, but a lot of them have no clue. Pretty much every time I sold a car, it was painful to watch the buyer during the test drive.

Have a GoPro to mount and video the tire?

Great idea. In for vids!

It is hard to tell sometimes. Best way for me to tell, if it isn’t squirreling back and forth, is to get on a clean area of road and try it. If its spinning at all you should see some sign of faint black mark in your mirror. What a day we live in, where cars are so powerful we can’t get traction in fourth gear!

Alternatively, you can start the car from a dig in 3rd. That too can force a bad clutch to slip.

Am I missing something here? 2 needles on the dash? If RPM needle goes up, shouldn’t the speed needle go up? And if speed needle doesn’t go up, keep your foot in it till you smell it and remove all doubt. 🤔

Starting in 3rd with the torque these make and going WOT is a good way to smoke a pretty good clutch

When the 5th gen ZL1 came out and we modded a few to 700whp right away it was pretty easy for those guys to waste the stock clutch with one bad launch on a prepped track and tires. So be careful with how you “test” it in case your clutch is still decent as of now

Agree, I wouldn't do that.

Do the highway test from 60, if it slips then you need a clutch anyway so no harm no foul.

I like the GoPro idea
