Ride comfort and ground clearance were both areas of concern for me. You maintain that the differences are slight...yet Porsche seems to be concerned enough about SPASM highlighting the Cab's lack of torsional rigidity that they refuse to offer it with that car, and the OP is willing to spend serious money to switch. I guess it's strictly up to individual taste. My budget is such that I'd prefer to get it right (for me) the first time. In any case, I'm looking for a coupe. All the Cab does for me is to highlight the fact that the 911 was designed as a coupe. BTW, your car is awesome...

Now, for the other side of the question: would it be just as much of a hassle/expense to change in the other direction...that is, to go from SPASM to PASM? I'm looking for a refined GT more than an aggressive/track car, and so in my search I have been passing over all of the cars that have the SPASM option...and there have been plenty. My guess is that it would be equally difficult, but I had to ask.

But you should also read the Total 911 GTS super test they were very impressed with the chassis of the Cabriolet ...

I agree with you, get what you want. All personal taste as you said. Like mentioned finding a non SPASM car is easier than finding a SPASM one.

I'm looking at C2s (with PASM) and C2Ss. Maybe it's the combined option load I'm looking for (standard wheels, SC, SD steering wheel, glass roof), but many of the S cars that fill my checklist also seem to have SPASM. There appears to be more Ss with SPASM than base cars with PASM. I think this is going to take awhile...

is an option that a dealer would ever tick when building a car for their inventory
(although I think Brett has done this in the past, he is somewhat unique)
Even more rare as a base option.... so I am not surprised by that
good luck with your search

My educated guess would be that about 20% of them have SPASM.

I emailed SunCoast and this was the reply:
To be quite honest we're not 100% sure if everything is a direct swap over. We've never done this conversion and I'm not sure if any programming is required. From a quick glance it looks like you would need front and rear springs, shocks, sway bars, and sway bar bushings. A quick total of all that is just under $3,800.00.
When you're swapping out suspension it's usually our recommendation to go with an aftermarket adjustable system because you have more flexibility and the price is usually a lot cheaper. And again, we've never done this so we're not sure if everything is plug-and-play. Try to do some research and see if you can track down anyone who has done this before and see what they say

thankfully the seller included the oem spasm springs and I had them installed inside of 2 weeks of receiving the car.
oem is best for any street use at all.
