2013 FRS Front Wheel lifting
I have been having this issue for quite some time now. When I am going around a very wide and long curve, like overchanges to highways. The slightest bit of acceleration and the front tires will slip. If its a very long left turn, if I start accelerating coming out of it, my front tires slide to the right slightly before the tc kicks in. Something is wrong and its been happening with multiple different tires. I just put on Firestone Firehawk Indys and it still does it. This is all dry weather in South Florida. All the shops I take it to say they do not see anything wrong. I mentioned it to the dealership and I am not sure if they really looked it over but all the tireshops do not see anything. If something was bent, would they see it when they do alignments?

Stock suspension? Factory spec alignment?

For the front to push more as you accelerate is normal.
Performance Driving 101: on the gas => UNDERsteer Despite "The Fast and the Furious"... Factory near-0 front camber doesn't help though, you might consider camber bolts. |

As long as alignment, tire pressures, and generally nothing is borken (dealer/alignment shop should have caught the last one if they're at all competent) it sounds like the car is operating as it was designed.
Post up alignment sheet. |

While this may be true in general, I don't actually recall my car ever understeering under throttle. It does want to straighten out a bit sometimes, but not enough to break the front tires free. I don't think my tires are sticky enough, nor the cars output torque-y enough to shift weight back enough to cause the understeer. That might be different if OP is boosted?

If even under throttle in turn due weight transfer car doesn't understeer, it's either setup too oversteer-ish to compensate lack of front grip or one drives slower/below tire grip capability.
After all, understeer or oversteer by definition is which end looses grip first when on limit. Mass transfer is most common way to adjust front-rear grip balance in turn. If not close to limit, then obviously both ends will grip like for you. If on limit (for used tires grip limit) - then how it was for OP. If you are tracking yours, i guess you have some speed left on table, if it's on public roads, you do well not driving dangerously and well estimating available grip, for OP - he should go slower, or switch to grippier tires, or learn how driving inputs affect handling and then stop providing wrong ones if result is not intended. |

I don't think he's talking about plowing straight ahead with zero lateral grip at the front. It sounds like he's talking about increased slip angle at the front, which is to be expected transitioning to acceleration while cornering. Quote:

My car did not used to do this, and I am not going fast when it happens. If i was pulling any g's around the corner i would expect it. This is from normal driving.

I took a picture of one of the curves it tends to happen on when I was coming home from work just now. I will upload it when I get a chance but it is a very wide and long curve.

My car is all stock except for my rims and tires, I have Gram Lights 57Xtreme 17x9.0 +40 rim and the firestone firehawk indy tires (I like the tires a lot). So this should not happen even more so then on stock size rims and tires.

What size are your tires? I get this sensation on my winter tires. The weight unloads and they wander left predictably, putting me off track from where I was intending to go. This happens to me even when driving straight
