Possible to add PASM
 
I periodically see folks listing PASM components for sale in classifieds - how hard/involved is it to upgrade a base 991.1 without PASM (even maybe to sport PASM)? Before people start weighing in with ďyouíd be better off selling the car and buying anotherĒ :soapbox: - itís not important enough to me for that. Iím simply asking b/c on my 981 that I had I found a great deal on a gently used x73 suspension, install was reasonable, and I enjoyed it immensely so I thought Iíd ask the question. If the process is too involved then Iím fine as is. I did a search & couldnít find anything except people debating whether or not to order PASM during configuration. Thank you! -Dom

I think you should just lower the car several mm and call it a day. Adding the true PASM parts will be crazy $$$.

I'm not an expect, but when I recently ordered my C4S I was told all 911 have PASM. It was not an option. I could select sport PASM, but all that did was lower by 10mm. Maybe it changed between 991.1 and 991.2.

On the 991.1 PASM was standard on the S. Available as an option on the Base. I think you are right, that changed to standard on both for the 991.2.

If you're looking to lower the base 991.1 suspension, just use the PASM or SPASM springs to get the ride height you want!

Keep in mind, Porsche did not allow the SPASM on a cabriolet. Reason why.........I don't know?

I think according to a Motoman video on YouTube it was to prevent creaks and rattles caused by the lower/stiffer ride.

Makes sense.

Thanks for the feedback folks - this is exactly what I was looking for. I didnít know if was possible to put PASM (or Sport PASM) springs on the base? That might be my preferred route. Anyone have experience with this? Thanks again! -Dom

To go beyond speculation, check with TCP Racing in Jesup MD, one of the best there is of Porsche suspension mods: https://www.tpcracing.com

Latest - the 992 Cabs will apparently be offered with Sport PASM packages!

Tried these guys (sent them an email, havenít heard back), Will try calling them Monday. This question has basically morphed into: can you use PASM or Sport PASM springs to lower a base? If no one else answers will report back what I hear from them next week. Thanks for the feedback! -Dom

I would just stick with a high quality coilover and enjoy the ride.

If the PASM shocks ever fail on my car that's the direction I'm going to go.

With $$, anything is possible but probably makes more sense to go Bilstein Damptronic coilover setup or something similar. It’ll be likely better and overall cost less.
