Concerns about rear wheel drive and fishtailing in my ATS-V

[zinner]

It's normal. Now go head over to the Cadillac forum and leave us alone.

Problem here is no one on this forum can feel what you are feeling. Any of us could probably determine if it was normal in 30 seconds of driving including on, of and warming rear tires.


The video that was replied to my comment looked perfectly normal. Car sounded tame too. If I saw that without context, I would not know what the point was.

I never drive my M hard without dsc off or at least mdm (euro). MDM lets me slide to the point that you could visibly notice I was pointed the wrong way. I don't see that.

I'm going to chock this up to inexperience, possibly thin and/or crap, possibly off-temp tires, and a ton of power.

Put some fat extreme perf tires on and see if it grips more. Go do HPDE. Take it step by step. Most of us on here have learned this way, moving from lower to higher power cars and it will be good. Practice with nannies on, see when they catch, lighten them up (if possible), see what feels comfortable, take nannies off. This is a long process, and not to be rushed. Do it on a track.

This was exactly my initial reaction when the thread stated, I can't lie
I just keep going back to all "electronic nannies" being left "on". It's really hard to move the car that much (especially first clip) with everything "on", even on wet or snow covered roads.

I actually don't care about what bb1857 has to say because he is absolutely sure that I'm the problem without driving the car. It's OK to assume that but definitely not to be sure about that.

As I already said, the last clip is with half throttle. If you want another example of the first clip, just ask. I can reproduce it easily.

My tires are the default ATS-V tires, Michelin PSS. They are brand new.
It is not the US here, 4 Michelin pilot sport cup2 can easily cost 2K USD.

Properly warmed up? PSS is a capable tire. Worthless when cold, can overheat on track (I don't think your tires are overheated). Mine spin sooooo easy before up to temp. Even when it's hot here (80* F+).

Probably still just the way the car puts power down. Really hard to diagnose without being in the driver seat.

Dear god nobody is going to drive you're friggen car. If you are so concerned just get rid of the car. It's clear you shouldn't be behind the wheel of even a go kart at this point.

Go to a Cadillac forum and troll those boards.

For me properly warmed up is after two hours of driving with some hard accelerations. I can still reproduce it easily.
Of by properly warmed up you mean 15 minutes on track them I can tell you that it'll be very hard to reproduce.

Properly warmed means proper temperature range for the tire. The PSS can overheat in less than 20 mins on track.

Putting around town the PSS never gets to temp. Some spirited driving, or in this case just giving it gas a couple times would do it for the rears.

Going to be impossible to give you any accurate feedback without being there. Sorry but this isn't really a remote-troubleshoot kind of thing. Best of luck!

Was gonna say

[kingikra]

I have talked to the service manager here and we are going for a comparable few hours between a new test car and mine. This will give a very good comparison.

Anyhow, thanks a lot to all who have actually participated in this thread.
All the rest, have a good life... hopefully...

So many people here should not be owning high HP cars (M3/4 included). Some of the comments here...
