The most commonly used front spring rate you will find on the net is 175lb for the front for the foxbody's so I would think it would be a good place to start with your car. I run them in my 87 with good results, I can't speak to the rear as I use Team Z stock location stuff.

Of coarse weight the car. My guess would be 25o on the front springs
