rear springs

[85cutlass]

sorry guys for asking this question again. i recently got a 8.5in. rear and im putting it in next week. i need a set of moog springs. i have the 5658s as the front springs. the tires on the front are 225/60/14. the rear tires are 275/60/15, what spring should i go for. i want a stiffer ride then stock, but not overbarring. if i go with the 5391s rated at 142lbs, is this going 2 be 2 stiff? is the rear of the car going to stick up to high? Or should i go with a set of 5379s rated at 121lbs? i am looking 4 alittle stance in the car but not to wild. i also want a better handling car with less body roll. Really need inpute. thank you
