I miss SPASM on my first 991. My cab doesn't have it and it's definitely higher up and floppier, although it rides a lot better. I was surprised how much difference there is, SPASM is definitely rougher riding.

Please see the last two responses by gota911 and kitwetzler. Unless you are only using the car for stop-n-go traffic and short trips to the grocery store and post office, you will very likely appreciate having SPASM (and it's a mere $890 option, a relative bargain -- see steering wheel deviated stitching! ). The idea that you have to track the car to notice and appreciate SPASM is brand new to me. Not all spirited driving is on a track.

I have spasm. My 997.2 had spasm. I don't track my cars. I like spasm.

I think it has more to do with the condition of the roads we drive than the way we drive. Here in the La Jolla area I can drive my off road truck faster than my 911 on many surface streets. Good pavement is a different matter all together. I really will not intentionally hit those potholes at speed with the stiffer springs.

If I had a do over, Id get PASM (instead of SPASM) for the improved ride comfort and compliance over rough roads.
SPASM actually hops on rough roads while cornerimg.
I think PASM would provide more traction in those real world conditions.

I've had same experience of rear hopping on uneven roads during aggressive turns. I didn't know the cause but I have spasm. It occurs regardless of suspension setting. Dealer will let me test car without spasm.

Could be as simple as over inflated rear tire pressures. What ya running?

I can't speak to the 991, but I have SPASM on my 997.2 GTS and it is now on my list of must have options on any future 911 I buy.

Does anyone know how much suspension travel differences there are between the two setups?

Im at 30/33 cold.
Thats (-1) from Comfort / Partial Load.

Rears get to 36-38 when warmed up.
Fronts warm up to 34-36.
I probably would lower the rears, but any more than (-1) sets off the TPMS warning.

PSS tires BTW.
I think they like lower pressures than PZero.

I wish I could drive a PASM car for comparison.
I was impressed with the ride comfort on the Boxter loaner I had.
I never would have believed 20" wheels could ride so smooth.

Ride/handling trade-offs are extremely subjective to each individual, as all these answers and comments show!

There is a clear disadvantage to SPASM being more likely to scrape, if that is a concern for you. If your goal is a car with a more sports/GT personality than a pure sports car one (which your original question suggests), then get PASM; if ultimate handling is your goal, then you need SPASM or an aftermarket supplier.

The best thing to do is ask your dealer if you can try cars with each set-up so you can decide for yourself.

Thanks, Vic_50th, and everyone else who has weighed in. This really does come down to personal preference and priority - these comments have greatly helped answer the question for me - my needs appear to be better served by PASM than SPASM. Now on to the rest of the configuration - I could spend all day figuring this out...
