Steering wheel shudder at speed

I would make certain to get an alignment at the same time as new tires. You can insure more even wear on the new tires, and eliminate that as any cause of the problem.

Seriously Doc? I'm lucky to get 15k miles from my front tires. Replaced the OEM Michelin P's at 15k. No tracking or harsh driving.
I know everyone wants to always jump the gun around here, but the OP said the front tires were worn, and if the car sat for a long time, likely 4 flat spots as well. Sounds like they weren't inflated to the proper PSI as well
He should start with replacing the tires/balanced because he has to do it anyway. If that doesn't solve the problem, then he should look elsewhere.
Not knowing much about these cars isn't a crime, but walking into a shop with little knowledge and having them assess your suspension could result in one...

Well ok then. By all means, don't take it to a skilled person. Spend money, replace stuff, then declare victory.

thanks man. Anyway I'm biting the bullet and bringing her into a "porche specialist" to get tires (going with pilot super sport A/S 3+) and going to get the IMSB done along with a thorough evaluation and subsequent replacement of any components that needs it (coils, oil/air serperator, water pump, etc etc etc) gonna hit the wallet a bit but then she'll be all set for a glorious spring

1000% it's the tires. The front end feel on the 996 is very precise, and bald tires, or even old tires will exacerbate that effect. When I replaced the front tires on my car (the tires weren't even at wear bars, but was 10+ years old) I felt like I got a new car.

Just curious. How many different type/brand of tires do you run on your Porsche. How far past the wear bars do you run them? How old before you would change them due to "ageing out", 10, 15 years? Porsche recommends 6 in my Turbo manual.
OP has three different tires on the car.
"Front worn tires are both pirelli Rosso
back tire is pirelli p zero nero and another tire is pirelli all season plus."

Alright so car is in the shop and man is this gonna hurt the wallet.
IMS/RMS
replace crankshaft seal
coolant.
Replace fuel filter, spark plugs, ignition coils, drive belt, air filter, spark plug tubes, and AOS
Tires- Pilot Super sport A/S 3+ balance and alignment
And somewhat importantly Cup holder install and get the radio working
no issues with suspension components. Brake pads are around half... When those need replacement will need to replace rotors and pads but I should be good for a while on that at least.
That whole thing about these cars being reasonable to buy but pricey to maintain is spot on. The porche tax is real but after this I should have a pretty solid 911

OP, remind me not to send you to the shop with my car and a credit card to get the wheels balanced. Dayum!

Apparently my reading comprehension blows. Can you point out which comment this was specified in? For once I'm not being a jerk - I just can't see where this is stated, but you mention it twice.

You made the right choice and you should have confidence in your car now...A 911 for 14K should expect 5K in service I'd expect.
#27
A Porsche 911 for $14K just cries out "problem" to me that someone wanted to dump. It sounds like you've identified all the repairs needed and will hopefully be enjoying the car soon. Good luck.
#28
a bit over 5k is exactly what the cost is and I believe I'm still on the right side of the equation for how much the car is worth and potentially is worth down the line given current mileage and how I likely won't put many miles on it. We'll see

I think you're on the right track. Long story boring, I had a similar situation with mismatched tires (somewhat self inflicted) and after 3 weeks of super annoying driving, I put 4 new super sports on and haven't looked back. Given that you needed new tires anyway, this seems like a good place to start.
