I have a '90 SC that has the 1.5" eibach lowering springs w/ factory wheels & tire size. I use this as my daily driver & other than an occasional romp stop light to stop light will not be racing this or have it on any road course. I want to improve the handling on this car & I am going to start with replacing the shocks with the Illuminas. My question is, how much improvement should I expect from replacing the rear sway bar with a larger Addco one. They are available in 1 1/8", 1 1/4" & 1 3/8" and I beleive stock is about 1". It is a tough decision not being able to drive one so any info will be appreciated - what is on your car? How much improvement?
