You have a T-5. I can't imagine downgrading a performance car with Monroe sensatracs. The Konis may be great. I put Bilstein HD all around on my 2001 V70 T5 and they are great. They are not harsh like the Bilstein HD shocks were on my pre 2001 850s and 70 series. The volvo suspemsion changed in 2001 and the shocks are different. So either Bilstein put different valving in the newrer shock or the nature of the suspension is different. My advice.....you have special car with about 250 hp of smooth power. Keep the suspension up to snuff to match the power.
