Is it feasible to change my car to a luxury suspension package?

I prefer a smoother ride.

A website said that the Euro package is just stiffer springs, bushings and sway bar. That would not cost much to replace?

Welcome! Yes, it should be feasible to install the standard spring suspension. I bought the sport suspension sway bar for my CL to firm things up a bit. The Sewell website should list all the bits. Search here for the discount password (baron?) and there is a Sewell parts guy you can contact through the forum. If I were making the change, I'd change one piece at a time starting with the springs (and possibly shocks if they are matched to the springs). Also, make sure you are running your tires at the recommended air pressure. Worn tires can also right rougher, so check your tread depth. New tires (maybe Michelin Primacy on 17" wheels may also make things smoother.

If you want to go really soft, you may need to go aftermarket air.

Good luck.

I'm guessing you have 18" sport wheels with tire size 245/45/18? You could buy 235/50/18 size tire which really cushions the ride or down size to 17" wheels and tires

I think I will end up replacing the coil springs.

I can feel small jolts. Not what I expected for a luxury car.

I have to make a 4000 mile road trip soon.

It would be a shame to de-content a sports edition car since they aren't very prevalent and some folks spend a while searching for them.

That's exactly the size tire I went to on my 18's. The 50 profile does help some but the ride is still a little too jittery and unsettled for my taste. On near smooth roads there's always a constant, small amount of body motion.

My 400 manages to completely do away with this and just feels creamy smooth on these roads.
