I just installed coilovers on my 89. I used 275 10" springs. With a 9" if used a longer spring the perch would possibly touch the rim to get the ride height I want. I like it a little on the lower side but the 10" spring would have been perfect even if I wanted it only 1-1.5" lower than stock. The 275 spring is good on smooth roads but maybe a bit stiff for the bumpy stuff. If comfort with decent handling is what you want id go 225-250.
