GTS Understeer, Anyone Else Notice and How to Dial Out???

So 245s will fit the front of a 997.1 C2S? How do they sit on the 8” wheel? I might go that route with a 295 rear next time around. I believe I went as much front camber as possible on the front and zero toe and just had it on track. I wasn’t impressed and struggled with understeer bad, especially when I accidentally left stability assist on. Mostly tracking an S2k that likes to rotate and kill you, driving this car well was a challenge. My student had a 996 C4S and TBH it handled way better.

If you decide to get new tires I would avoid these: https://www.tirerack.com/tires/tires...ndard%20Brakes
Can't remember if I already mentioned this in another thread. Either way, worth repeating. Just got a new set of four of these to try something different than the Michelins. Grip and all other aspects are right on par with the Michelins to my senses but man.....the road noise. Brand new they howl like the Michelins did with 12,000 miles on them.

Just got them so haven't explored the full capacity yet but I take your word for it. What little driving I've done since mounting them, they really feel glued to the road. Getting used to all the racket and they look pretty cool too. Again though, anyone looking for a quiet, plush ride, this tire won't make you happy.

Driving on them to and from the track is enough!

Lots of wrong recommendations here. If you want to increase your oversteer then you could just: increase front tire pressure (on track we have very similar front and rear around 34-36 hot); add 245 tires on a front, more negative camber for front, and stiffer rear sway bar.
Learn how to brake unto the corner where you hard in the beginning and easy off at the end to smooth transition to gas. Usually opposite to what most people do. Go to a local DE event before you start investing in hardware or new tires. You can do a lot with just your wheel input and your feet.

I hear you. I usually do my due diligence before diving headlong into unknown waters and I thought I did just that before buying these tires. Didn't see any reviews on Tire Rack referencing excessive road noise but then, the reviews cover all kinds of cars so maybe the wide 305's on the 997 is the culprit. Went back and read a lot of the reviews again and still didn't see but a few of them mentioning road noise. But like I said, these tires are mounted on a wide range of cars, most of them with much narrower rear tires than 305's. So again, maybe the noise increases exponentially with the width of the tire.
Work mostly out of my home office now so don't put a lot of miles on the car and I'm ok with them. I actually like everything about them except for the howling at speed.

But couldn't agree more. Noise aside, great performance tires with a cool look adding to the overall impression.
