Default understeer bad

The other day I took a friend for a quick spin. I slowed to a reasonable but brisk pace and tried to make a 90 degree turn and the car just understeered badly straight nearly into a divider. Tires weren't cold.

Now I wasn't crawling but I wasn't whipping around the corner enough to raise an eyebrow so this really surprised me. I'm guessing it's time for swaybars.

Generous offer...but it might be a long drive from Houston, unless that's what you meant by the "city".

Is your car completely stock.

Fine a safer turn and try to reproduce before you start spending money.

A lot of times, just a better then stock alignmebt can solve a lot. Also, could have been some sand, debris on the road as well but just a rear sway and alignment is always a nice upgrade!

I had a simliar experience the other day but DID NOT brake hard enougth prior to the turn to shift the weight to the front of the vehicle and over the front tires. Had I done THAT is suspect I would have solved the problem. In other words, the understeer was pilot error.

Comments from any track-heads?

I thought about that too. Usually I'm not driving aggressively in town. I like to leave it for trackdays.

I thought about that too. I do think the surface and temp (early morning) had a lot to do with it. I need to have an alignment done (I believe you had a good thread on your specs).

Not a track hound, but had this once in the first few months of (new) ownership.

It was a slow mountain twisty, maybe 30, and I thought I was going off nose first.

After that, I adjusted to taking the turns a little faster and it never happened again.

GMG Sways and an alignment did wonders for me. I did it at the same time as the GMG springs, which for the record, are incredible.

The understeer could be from many factors. I would start with the gt2 rear bar and a good alignment, next lower with springs and rear toe bar. I'll be happy to take you or a spin.

LOL. Now wait a minute. Let me get this straight. You're saying that you experienced under-steer in your TT at normal speeds? NFW! Remember- you can fool all of the people some of the time but not some of the people all of time. So come on! What's the REAL story? LMAO!
