Has anyone notices that sometimes when at higher speeds on turns , that the front end can get a little erratic or turn in harder than expected ?

For example if your accelerating on an on ramp that is particularly curvy ? its whats weird is it feels different than loss of traction on the rear end , more like steering getting more sensitive and I have to adjust it

I was feeling the same, you have to adjust your tire pressure, if you want less oversteer go for 35 psi front and 30 psi rear. you can try different tire pressures and see how the car behaves. Remember that when hot, tire pressure increase by about 3-5 psi.

Is this your first higher powered rear wheel drive car? The throttle has quite an influence on steering. This is a good thing.

LOL this is the main reason for owning this car over an RS3/A45.

Love the steer by throttle adjustability

Does it feel like your rear end is jumping a bit and or bouncy? If so, I've felt that many times and that is due to a poor rebound setup in the suspension by BMW.

To clarify a little , the rear end feels fine . Its not a "slide" nor does it bounce . But the issue feels like the front end .

For example I am going at a higher speed on and on ramp with consistent throttle turning in sometimes the car starts to turn in much harder than expected ( but not because of a fishtail from extra throttle ) .

The tire pressure comment actually makes sense , mire tires are at 38psi - so that could be part of it

It's been a while since I've played on on-ramps but in general, the M2 Comp has slight understeer with neutral throttle at the limit but less than most cars. IE with constant steering and a slow increase in speed, the front tires should begin to push out. Backing off throttle brings it back to neutral. If not understeering, it could be a tire pressure issue as discussed.

However in sport modes, the M2 Comp allows a lot of play with the throttle. A quick stab sends the backend out (but not if already in understeer). A quick cut of the throttle can also cause the backend to kick out. This is because of weight transfer to the front. The rears loose traction and kick out. Is this what you are describing? It can be fun and useful to do this but scary if not used to it.

I recommend a 1 or 2 day M School. It sounds expensive but teaches a lot of these things with lessons on wet skid pads. Or join a BMW CCA and look for a "club M school" That's a 1 day school at 1/2 price. You drive their cars (M2, M4, M5) and learn a lot while having fun.

Its also getting warmer out. I've definitely noticed the Michelins don't do as well when the ambient temp is below about 70 degrees. I mean they work fine but the grip increases significantly as it gets really warm out. You might have just been scrubbing a bit more in the past.

That doesn't sound normal.

As if the car is deciding to take a deeper line that you did not adjust to?

Maybe something is loose

[chiefsubjugator]

My experience driving this car near the limits is that I get a tiny bit of understeer early in the turn, then once I hit the apex and slowly start to apply throttle the front digs in and the car starts to point back toward the inside. Maybe that's what you're feeling?

I've experienced this with my current car. Going around a corner is stable, turn in a little more, and it feels like it suddenly darts inward. Mine turned out to be an alignment issue. Check the front tires for eneven wear. Mine were really worn on the outer edge, but barely touched on the inside. Not the camber numbers one looks to have. Car was still reasonably new so I assumed the alignment was good. I never cared for the handling much, then I had the alignment performed. The referenced issue disappeared.

[Gruz]

this exactly

Going around a corner is stable, turn in a little more, and it feels like it suddenly darts inward.

does not feel like a power slide or fishtail , more like the from tires getting pulled into the turn .

I will check the tires

Definitely.

This happened to me when I first got the car, but I think it has a lot more to do with not being used to a car with such quick steering. I’d subconsciously go to tighten my line a tiny bit with the steering and find myself tightening the line too much. I think I also probably assumed I was at 9/10ths when I was likely only at around 7/10ths, so the front tires had plenty left to give when I turned in a bit more. Hasn’t happened to me much lately now that I’m used to the quickness of the steering.

Also maybe check your steering settings (comfort/Sport), i find stiffer steering feel can help. If you drive with comfort for the steering but in Sport+ mode, sometimes i find its too loose and sometimes i find myself turning the wheel more than i want to because its so easy

[AlpsRider]

38 lbs is way too much pressure for that car. If you're not hauling around weight in the car I'd recommend 34.5 morning cold pressure all the way around and go from there.

If they are 38psi when you start the car ie cold temp then that is too high should be 35 or 34 cold temp. This car reacts badly to higher psi. Had 38 on rear and it had bearly any grip and was very bouncy at extremely high speeds.
