Advice On Limited Slip Differential And Sport Suspencion

[robingates]

I will be ordering a 2011 911 C2S in the next week or so and am looking for advice on the sport suspension and limited slip differential options. I will be getting the Sport Chrono option and I am seriously considering adding the sport suspension option. This will be a daily driver but I will track it one or two times a year. I tracked my previous Porsche and had made a number of suspension modifications to improve the track experience. However, I am concerned that the sport suspension in normal mode will be too harsh for daily use. Does anyone have an opinion on how hard the ride is on the normal setting for the C2S standard suspension compared to the sport suspension?

Also, I am not sure whether to get the limited slip differential. It seems like its a bit more that I would need since I plan to track it only 1 or 2 days a year. Any advice here?

Thanks.

I have an '09 C4S with sport chrono and and sport suspension. My C4S is my daily driver and I drive it about 2,000 miles each month. I seldom put it in sport suspension mode because it does make the ride pretty rough. It is OK temporarily if I know I am going to be pushing the car through some winding turns.

My previous vehicle was a Lexus SC430. Compared to the ride of the Lexus SC430 even Porsche's "Normal" mode is a bit rough but then I always thought my Lexus was too mushy and anemic. Also the C4S is considerably noisier than the Lexus but that did not take me long to become accustomed to. Usually I am the only person in the car so the rough noisy ride isn't that big of a deal. If I want a quiet soft ride I take my wife's Lexus LS-460.

FYI the original tires lasted 19,000 miles and the replacement Michelins from Discount Tire cost almost $2,000. Be prepared for the expense of maintenance!

If you're talking about the P17 sports PASM suspension, it comes with the LSD as part of the package-unless something changed for '11.

A few months back, "Excellence" ran an article comparing the sport to the regular PASM with 19" wheels and their conclusion was it could be used for everyday street use (not on 'sport') without shaking your fillings loose.

Do some research on the LSD however, it seems the longevity of the LSD is minimal-especially if tracked.

I have the sport PASM (equipped with LSD) on my 2009 C2S. Despite some pretty bad roads that I have to drive regularly, I find the normal setting to be very tolerable. Perceived ride quality is very subjective, of course, but unless you are expecting a luxury car ride, I don't think you will be disappointed with the sport PASM. The ability to switch to sport mode if you do any autox or track sessions is a big plus, without compromising the car for daily use by making aftermarket mods.

I recommend the LSD which you can get with either suspension. Because we drive mostly on real world roads I did not get the SPASM. The 997.2 std PASM is a great suspension and I can always put in Sport mode.
