Is there a possible way to change struts and/or coils to get a soft ride on a 04 acura tl.

So I guess 07-08 base TL shocks and springs along with a set of Michelin Primacy MXM4 tires (and to go another step, 16" wheels if you have an automatic)

 

If you can go stock, that's your best bet for a soft ride. Otherwise, the Tokico HP Series shocks are one of the more comfortable aftermarket shocks out there.

You could also go with OEM springs or maybe TEIN HTech if you want it a little lower but still relatively comfortable.

and as Robocam said, go down to a 16 inch wheel with lots of sidewall for maximum comfort.
