So I've (finally) been able in finish my first round of mods which can be seen in my sig. Now it's time to look ahead for stage 2. I'll be getting the FE3s in this summer. I've been going in steps because I don't want to introduce any new NVH to the car. What would be a good next mod to tighten things up a little more while still retaining the car's basic comfort? I'm thinking sways but have heard of a couple of noise issues (grease?). Have also read the GM endlinks are actually pretty good. Also any input on what brands have held up over the years? Cheers.
