Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'Check tyre pressures and wear characteristics etc' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check tyre pressures and wear characteristics etc' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi first of all apologies for only ever asking questions and never giving advice I promise i will get better!!!
My 996 C4 feels a bit different at higher speeds. The front end seems quite light on dual carriageways at around 90 ish. Also i am getting a body shake but not through the steering at anything over 120. I am assuming its an aerodynamic problem. Anyone got any ideas? Many Thanks.
More likely to be tyre/geo related ie. mismatching, tracking/geo misalignment, pressures etc.

I am by no means an expert, but I had a similar situation with my 02 targa, especially the lighter feeling at the front end.
I also had the shakes once it got towards three figures.
Both problems were solved as soon as I had new tyres fitted, although I did have the alignment done at the same time so that could have contributed.
The car felt 100% better to drive immediately as I left the garage.
Hope that helps.
Hi,
You will get a lighter feeling on the front at 90ish, the front will lift however this will settle down from 100plus onwards. All variants of 911 have the front lift, more evident in c2's. Assuming you are doing a bit of spirited driving to get to 90!
Best to get geo set up. There is a thread about a good place to take your car for a set up.
Regards Alan
Without wanting to sound too controversial you really shouldn't mix tyres on a Porsche. A few will say it's fine, my personal experience is not to, you can experience strange handling traits etc
Get the geo. alignment sorted, you OPC can do this or a decent independent with good experience in such matters.
