Shuttering While Cornering Hard
I've got a 2013 Subaru BRZ, I've had it for about 3 and a half years, and it has 220000kms on it. It's my daily that I drive about 200km a day in so I rack up the kms pretty quick!
Anyway, I've had an issue that's just recently surfaced. When I corner hard it seems to shutter/shake, only on the limit and it's when I start to get on the gas. This leads me to believe its maybe wheel hop? Incase there's any other issue it could be that's not wheel hop I thought I should ask. If it is wheel hop, what seems to be the most common cause of this? The car is 100% stock. |

How are your tires? I found when my FRS tires were at the end of their life they would give the traction control fits when cornering.

They’re definitely getting worn out, hoping to get the rest of this summer out of them. If that’s the issue that would be easy! Sent from my iPhone using Tapatalk |

Quick test to confirm would be to long-press the traction control to defeat it. Don't worry. It's not like the car suddenly becomes a Mustang.

Rotate your tires. See if the behavior changes.

Worn struts can also do this...

And bushings, bearing, etc, etc.
Start at the parts that touch the ground and work your way up.

Perhaps stating the obvious, but this sounds like understeer to me. Coupled with the "only on the limit", have you considered that this might be driver input (e.g. a result of your braking, weight transfer, speed and steering wheel angle being incorrect for the corner?) I ran into this when I first started HPDEs... even though I was slower than I am now.

I suspect that is the "shuttering*" he speaks of.
*Shuddering Shuttering while turning would indeed be a pain!

Not to be confused with stuttering.
