Not sure if anyone can help, but here is what I'm curious on. Looking to swap out my still factory saggy springs. 79 Malibu with the 267 and ac. As it sits now the front tires are 215/70/15 and sit at 25 1/4 inches from the ground to the fender opening. The rears are 255/60/15 and sit 25 1/2 inches from the ground to the fender opening. Took it for gas today and on a flat surface she definitely looks like she's been lowered, but with worn out springs the handling is horrible. What I'm curious on is what is the best spring to run. I like a pretty firm, solid feel and will be running these with bilstein shocks. So far I've narrowed down the fronts to moog 5658, 5660 or 5662 springs and the rear to 5413s or 5409s. I don't mind if the height raises a bit with maybe even an ever so slight rake. I've gone over the sticky Moog chart but still just not sure on the best spring and/ or spring combo. With any that you guys recommend would you cut them or not and if so how much. Thanks
