Tommy, if the springs are old and kind of sagging, you may suggest to your friend a new set of H&R springs:
Products | H&R Special Springs, LP.
Their OEM springs lower the car just a bit (+/-) 1/2" and they are pretty affordable too.
When my son had to replace the struts on his Jetta, we added a set of H&R's to the Koni's and the handling was amazing afterwards, without any noticeable stiffness.
