I have the sport pack on my T3, with the 225/R18/40 Midar on, and the ride is not that hard. Haven't driven one yet with the normal suspension, so not to sure how it feels. Had a big S80 as loan car for a few days, and the suspension was so soft, when I go over speed bumps, the car hits at the bottom. My T3 on the same bumps certainly doesn't feel like a jumping castle.
I prefer a nice sporty suspension, and had the privilege to drive a V40 T5 R yesterday, now that is nice, and the suspension is apparently even harder than the normal sport pack one. I must admit, I liked it more than mine. Both mine and the T5 R has adjustable power steering, so you can decide how much of the road you want to feel. Also, it is only 10mm lower.
