In the 11 gen SI there's not suspension adjustment, just steering and motor I l believe is the same in the sport version, that suspension option is available only in the type R
TBH I was feeling the same when stock, for that reason I switched to coilovers the ride is smoother and I can drop the height of the suspension for better look and feedback, check out the Silvers coilovers after 3.5 years they are running like the day 1 without problems.
