Hello all; I am looking for a solution for the rear springs on my 1990 Acura Integra 4 Door. The problem is that carry about 225 pounds of extra weight in the trunk daily between stereo equipment, deep cycle battery, tools and equipment for work. I was running an air suspension with 4-inch cylinders on the rear to compensate for the weight and it worked well but the roads I drive are too hard on the cylinders and in the winter they tend to leak on the colder days so I am switching back to springs. I have not been able to find any stiffer or higher rate spring out of the box unless it is a lowering spring; which I do not want to do, I just want a normal ride height. I found custom spring manufacturers on line and I was wondering if anyone could recommend one that they had a good experience with. Another thought I had was installing a set of Front Suspension springs on the rear, Does anyone have any kind of specs for the factory springs such as free height and rate? Does anyone know if a set of front springs could be installed onto the rear struts? Any info would be appreciated.
Thank you: Michael
