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.

Suspected cause
I thought the issue was the suspension design and the fact that larger wheels are heavier.
Leading evidence: 'suspension design and the fact' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'suspension design and the fact' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Use rims and tire' (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.

Suggestion
You should calculate this using the rims and tire.
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.

I found a set of 19" 997 Turbo wheels with tires for sale and am trying to find out if they will fit my 2004 4S . I have chrome standard twist wheels now ( fronts are 225/40/ZR18 and rears are 295/30/ZR18 ) . The seller has Pilot Sport Cup tires on these Turbo rims ( front 235/35/ZR19 and rear 305/30/ZR19 ). He says they would fit fine except that the rear tire would be too tall and I'd have to buy a different size tire. I don't mind swapping tires if the rims will fit without having to modify the suspension or the fenders to accomodate this size. Have any of you guys put these rims on a wide body 996 ? What size tires did you end up with ? Any problems ? Any help is appreciated - thanks !
I have heard that in the 997 the differential is different from the 996 and the difference circumference of the front and rear tire is more accpetable in the 997 than the 996.
You should calculate this using the rims and tire. Tires do make the difference in wrecking your 996 differential or not...
So, are you saying that if I have 40 series tires in the front and 30 series in the back, I'll need to go to 30 series in the front and 20 series( do they even make such a size ? ) in the back to keep the overall diameter of the wheel/tire the same as what I have now ?
I asked this question once and from what i remember it will affect the diff. Only the replica turbo rims come in the appropriate size. A tire/wheel person can hopefully clarify this for all of us.
Your differential doesnt care if your front and rear tires are 23" tall or 27" tall, all that it cares is that they are the same or extremely similar between the front and rear.
Mark
yeah, but the 4S comes standard with different profile tires on the front and back already ( 40 vs 30 ) which , unless I am missing something , are not the same or very similar . Is there something I am not understanding here ?
I thought the issue was the suspension design and the fact that larger wheels are heavier. More unsprung weight than the suspension is designed for will affect handling. that not true?
This is a source reference. Confirm exact model applicability in the original material.
