Good morning fellow 992 owners.

The 992 register has received the following enquiry by email from one of our members, Yaqub, and I was wondering if any of our more technically minded 992 owners / enthusiasts might be able to help?

Yaqub had a 992 Turbo S with sports suspension and has recently replaced it with a similar car that he didn’t realise doesn’t have the sports suspension option. He tells me that there are some disappointing reviews about the harsh ride and handling of these cars without the optional suspension.

He tells me that he does a lot of track days and has owned a GT3 previously but needed a car that was more practical and the 992 Turbo S fulfils that brief perfectly. He is hoping to be able to keep up with race cars and GT3s on track (with the right tyres and suspension geo) and is feeling disappointed that he missed the fact that the car that he bought doesn’t have the sports suspension, although he also tells me that on the road, the car is amazingly comfortable, and compliant and he really likes it.

His specific questions are:

Will he notice the difference on track as an average driver?

He goes onto say that some reports confirm that the angle of the spoiler and front splitter are different, so might just be more than a lower stiffer ride. How much will he notice this on track?

Will the handling be considerably worse or will the difference be marginal that only an experienced track day driver or racing driver would notice the difference, bearing in mind that he is actually happy with how this car performs on the road.

Failing that should he replace the Turbo S with another GT3 or a GT3 touring?

I’m afraid that I don’t have any personal experience of a Turbo S, although I did have an early 992 Carrera 2 S, which I thought handled vey well, although I find my GT3 a more exciting prospect to drive. The GT3 to me and my wife is very comfortable and compliant on the road and is perfectly balanced for track days for someone like me who is a less confident and experienced track day driver. In fact my daily driver, a. VW Golf R has a much harder and unforgiving ride on the dreadful public roads around Cheshire which are riddled with bumps and pot holes…

I personally happen to believe that all of these points are subjective and depend on the driver, but I promised to ask the questions which hopefully may generate some discussion and help in turn help Yaqub.

Many thanks,

Martin
 
Interesting question. The Sports suspension option comprises Porsche Active Suspension Management with sport tuning for springs, dampers, anti-roll bars (or PDCC), PASM and Rear Axle Steering and lowered by 10 mm (0.39 in). It has shorter springs and higher damper rates with helper springs at the rear to fill in the gaps.

The Turbo S is already firmly sprung as standard and is the better option for road use in UK IMHO. The 'SPORT+' mode is the go-to driving mode for track days with instantaneous throttle response, lightning fast gear changes, and overall steering and suspension being firm and responsive.

The Sports suspension option reduces body roll and improves road holding with undoubted advantages in a race car situation. However, for the average driver, Sports + on a track day will provide adequate driving enjoyment with thrills a plenty, to the extent that any Sports option improvement will be marginal and largely insignificant.

By far a greater gains will be had by commissioning a bespoke chassis alignment set up by an independent expert. Small adjustments to Turbo S geo make a huge difference in handling and road holding. Many of us have found these cars often need adjustment even from new and to illustrate the point, the factory currently has a campaign to check alignment at first service!

You can read more about chassis alignment from a thread in the 992 technical section here (you need to be logged in to access it).

Clive knows his onions, so Yaqub should find all the info on the Turbo S above and with the link. Mine has the lowered suspension option and was also setup at Centre Gravity which made a noticeable difference - the factory settings were out of whack when measured on the Hunter machine.

Martin, you know the 992GT3 well, and from memory I do not think the NVH of the car is any worse than the 991.2GT3 that I had a few years ago. I can hear the radio in the Touring fine, not that I have it on that much! The Turbo S is great fun on track but if you're chasing times then the GT3 will always be quicker on the twisty bits.
