Understeer on 997.2 TTS
Just moved into 2012 997TTS, love the car. I am noticing understeer a lot compared to my 993 C4S. Just wondering if any of you have experienced this. I have had many 911’s and have not felt this before
For comparison I went and drove my friends 991-GTS and that felt exactly like my 993.
2012
mileage: 12,900
tires: Michelin about 600 miles on them
car is completely stock
Any information would be appreciated
Absolutely love this car!

Normal, more so at lower speeds.

I think it's normal too, unless of course something is truly broken or out-of-whack in your suspension/alignment. I can't compare to a 993C4S but all 911s in general have that unique feeling on low/medium speed corner entry. I added the slightly larger GT2/GT3 rear swaybar on my .1, which helps a bit. Also I have the DSC suspension controller which remaps the damping and really cleans-up the handling.

Yeah, first time I felt it I was entering a sharp turn at maybe 15mph. The push was surprising and noticeable and my reaction was, "ohhh, there's that 911 understeer I'm always hearing about."

Thanks so much for your response. I will test a little more but it was surprising to me

Get your alignment checked. My 997.1 turbo handled like garbage, understeer on right turns and unstable oversteer when turning left. I got an alignment using gt3 specs and now handles like it should.

An alignment and GT2RS rear sway bar helped significantly reduce understeer on my 997.1. It now turns in superbly, and I wouldn't go back to stock.

Presumably 997.2 has the same issue but 997.1 turbos are limited as to how much negative camber you can dial in. If you really want your car to come alive you will need to install gt3 lower control arms or camber plates. I am running -1.7 front and -1.6 in rear. GT2 bar in back, DSC module, Tarret rear toe links and stock springs and struts, handles great.

I've always been interested in the recommendation to install rear toe links, under the premise of being able to get the right alignment post install of lowering springs.
I've got GMG springs installed and other than GT3 LCAs in front and the GT2 rear sway bar, I've not installed anything else. I've also not had any issues with dialling in the alignment I want.
What do the after market rear tow links enable that the OEM links can't do?

The aftermarket toe links like Tarett have a wider range of adjustability than OEM. I also got a Tarett rear toe locking plate. Our car's handling is pretty sensitive to the rear toe settings and it is relatively easy for the toe setting to change. The factory cams slip under heavy loading resulting in alignment changes. The locking plate helps prevent that from happening.

If you have the locking differential and apply power in a slow turn, would this not cause some "push"?
