They'd work just great, although any aftermarket spring with stiffer spring rates and lower stance will wear out the struts faster (maybe twice as fast at the most I think). If he's interested he should do his own research, but I'm pretty sure they are identical to the sedan version except just slightly stiffer rear spring rates. Stiffer rear is good (sedan or wagon) in my opinion because you'll get less ass sag, add stiffness to the rear which helps prevent body roll (just like a rear sway does), and stiffer rear springs wouldn't make the ride noticeably harsher for front seat passengers.

As long as they fit and the springrates are higher in the rear and the same in the front (and I'm 99% sure they are), I'd actually recommend the wagon version over the sedan version for a sedan.
