911T4ME

I'm a new owner of a 2019 911T. I have already tracked it and other than noticeable understeer (I plan to get an alignment to max out front negative camber) I thought the car was great. I tracked in Sport+ mode exclusively.

From what I understand, the DSC controller allows the SPASM to be custom programmed to settings other than the OEM normal and sport suspension settings (20% and 80%?) For example, 00% and 100% so that in normal mode the suspension is more compliant and in sport mode its as stiff as possible.

Do I understand this correctly and more to the point, for spirited street and track driving is this upgrade worth it and if so, why?

”slow in, fast out”

it’s more than that. It turns your passive adjustable dampers with static modes into an active controlled system that dynamically changes depending on how you’re driving. It’s also programmable, so you can fine tune it for specific conditions/tracks/etc. I would suggest watching some videos on YouTube that explain it and how it changes the car.

This video will have some commentary and explanation even though it’s a different car.

Tons of threads on this thing, lots of people who drive on the street says it's an absolute game changer, and several people who actually drive on track say it's an incremental upgrade. Take your pick on who to believe, it's Rennlist and it costs a lot of money so not many people are willing to admit they bought something they don't love.
