Does the Cayman S actually perform better with 19 inch wheels or 18 inch wheels, or is it just a 'looks' thing? I am ordering one with PASM and sport chrono, but have never tried 19s. Do they where as well as the 18s? Is there more noise inside the cabin with the 19s?...
PASM - Porsche Active Suspension Management
This active damping system offers continuous adjustment of individual damping forces based on current road conditions and driving style.
The driver can choose from two setup modes, ‘Normal’ and ‘Sport’, using a separate ‘damper’ button on the center console. ‘Normal’ mode is designed for general road driving and circuits with uneven tarmac. ‘Sport’ mode is intended for smoother track surfaces, where the harder settings help eliminate pitch and roll.
In either mode, PASM continuously evaluates the current conditions while automatically selecting the corresponding damper rates from the respective set of mapped values.
A range of sensors are used to monitor the movement of the body under acceleration, braking and cornering maneuvers, as well as on poor road surfaces. The PASM control unit then evaluates this data and modifies the damping force on each individual wheel in accordance with the selected mode. The result is a significant reduction in body movement as well as a better grip on the road.
For example: if ‘Sport’ mode is selected, the suspension is automatically set to a harder damper rating. If the quality of the track surface falls below a certain threshold, the system immediately changes to a softer rating within the ‘Sport’ setup range. When the quality of the tarmac improves once more, PASM automatically returns to the original, harder rating.

Sport Chrono and Chrono Plus
This optional package is a valuable addition for trackday use. Available in conjunction with the CDR-24 CD radio, it includes a swivel-mounted analog and digital timer unit which is centrally located on the dashboard. All functions are easily accessible via the control stalk for the on-board computer. Analog dials measure hours, minutes and seconds, while a separate digital field displays whole seconds, tenths and one hundredths of a second. A second digital display runs in parallel in the instrument cluster. Click this Link to visit the FAQ entry for Sport Chrono.
The 19's look much better on the Cayman, especially due to its large wheel wells. I would have to say that if it was strictly for performance I would go 18's because you are bound to be saving a little weight if anything.
I have the 19' Sport Designs and love them. I think they are the best looking wheel I have yet seen for the Cayman! But then again, I am biased of course[img]/fckeditor/editor/images/smiley/MWPX/thumbsup.gif[/img]
Do you think it would be a mistake to put the boxster s wheels on a cayman s? I think they look better than the stock cayman s wheels, but perhaps boxster s wheels are not cayman worthy...

What do the Boxster S wheels look like? Got a pic?
19's are mostly for looks.....if that's what you like. IMO the 18's look the best on the car though as the 19's tend to make the brakes look small, the 18's seem to frame the brakes perfectly. A lot of professional drivers also like the 18's for driving 'feel'.....and so do I. The 19's will offer slightly more grip on a nice smooth track though. The interior of the Cayman is not a quiet place to begin with, but I didn't notice any more noice with either size tire/wheel. IMO....if you are not hung up on the 19' wheel look, stick with the 18's. They look great, are easy to clean, tires will be cheaper, and best of all they're free!
The 19' wheels perform better in corners due to less flex in the side walls, it is a noticealbe difference. You do have a rougher ride for the same reason. As far as noise is concerned, that is not a function of the wheel but of the tire tread. If you look at Porsche's alternatewheels none of them are 18s, and this company rarely does anything for looks.
Without objective data, I would not venture an opinion as to the relative driving merits of 18 or 19. But there are two factors favoring 18s. One is that a set of tires is about $200 less, and that if you are racing inclined, there are many more choices of tire in the 18 inch size. Or so I'm told. As far as Porsche not doing things for 'looks', direct your attention to the option list - leather, aluminum, carbon, etc. etc. etc.

.........or money for that matter. I think the factory wheel options for Porsche's are one of the biggest money grabbers on the list.
There was an PCA auto-cross last month and a Cayman S on stock 18 inch wheels and tires set second fastest time. Unless your a very very good driver I don't think you would find much difference.

I do not know if this is true, 19' wheels are better because there is less flex in the sidewall...the sidewall of what, the tire? I think you can get a tired rated the same for each size, and the 18' wheel will be lighter as will the tire, both an advantage with less unsprung weight...The 19' will ride harder/louder, I agree with that...andI would dare to say that Porche doescare quite a lotabtpleasing the consumerin the 'looks' dept.
Thanks much for the feedback. I guess I'll just have to do a test drive comparison, but I'm leaning toward the 18s at this point because I'm no track star--just dabb;e a bit--and I ocudl use the cash for some other everyday options, like self dimming mirrors. tThanks again.

I believe there is a comment somewhere that Walter Ruehl (sp) said something about if you want the fastest time, use the 19' but for everyday driving, the 18' would be easier to live with.
Yes, there is the unsprung weight thing but unless you RACING ... actually racing maybe in autox, you won't notice it.
I was thinking 18' but ended up with 19'. The turn-in IS quicker. I could 'feel' it. The ride is not harsh at all. I'm used to a really tight suspension and while you do feel some bumps on the road, it aint bad at all.
