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.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
On Caterhams, for example, it is widely accepted that the smaller the wheels the better the handling, and the very fastest cars (SLRs, R500s etc) run on 13" wheels.

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

I am unsure whether to fit 18" technology wheels on my 1998 C2 which has the sports pack (030 suspension, etc), these have been taken off and standard 17" fitted; the car handles well and I am unsure whether to go for 18" .... not just for looks. I have sourced some wheels from PORSCHE APART. The reason I ask is that my previous C4 had 18" sport design and I did not like the handling of the car with 18" Any advice, help would be appreciated in terms of performance rather than looks !!! Thanks Mark

POST 2Original post

IMO most Porsches are actually nicer to drive on slightly smaller wheels. However, aesthetics rule and, over the last 30 years, 911s have gone from 15" to 16" to 17" to 18" to 19" and it is only a matter of time before 20" wheels are available. On Caterhams, for example, it is widely accepted that the smaller the wheels the better the handling, and the very fastest cars (SLRs, R500s etc) run on 13" wheels. There are a number of reasons for this. Lower unsprung weight is one benefit. Another is the function of the tyre as part of the steering and suspension system. Up to a point, tyres with a higher aspect ratio tend to be more progressive and more predictable. Also, the ride tends to be less jarring on poor road surfaces. Another consideration could be the make of tyres. Autocar reckoned that the 996 (on 18"s) handled better, and provided a more comfortable ride, on Pirelli P-Zero Rossos. Finally, this is all academic if the geometry is not correctly set up.

POST 3 / ORIGINAL POSTEROriginal post

Oliver, I would say that my 996 C2 handles much better with 17" and the sports suspension than the C4 handled with normal suspension and 18" I am not that fussed about larger wheels or the 'bling' factor and its down to personal choice as always. The car looks good with the lower suspension and 17" anyway, just trying gauge any benefits on performance. Thanks Mark
