My 1987 subaru has ripped the bags on its factory air ride suspension. I have sucsesfully converted the front to coil overs, but im having some trouble with the rear. I see many options for rear shocks but I dont know if I actually need the coil spring to go with. Since it was only the front bags that ripped, i have the car set up so I can fill the back bags manually. However, it is extremly inconvienent because the still leak and at different rates so everyother day I have to fill them with air. Any help is appreciated.

In your case...

...Yes, I would install Coil Springs and get rid from the Pneumatic Suspension.

 

Kind Regards.
