Yea they should fit. And fitting coilovers on non sports is exactly the same as on sports.
There is quite a collection of threads in the guides section explaining how to fit coilovers / remove shocks / springs etc.
They most confusing bit is working out which bits you transfer from the old shocks on the front, and working out the order the washers etc go on the rears.
I did it on mine. Just make sure you get the wheels all aligned after, or the steering will feel horrid!
