I currently own a 91 s10 with a 350 and looking to ran a set of qa1 coilovers but not sure which spring rate to use. stock the truck weights about 3100lbs and naturally my front end is alittle heavier with the v8

all suggestions and opinions are weclome

Not sure but I think the GM guys would know better. I run QA1's but they are not coil over.
