I'm currently on stock springs, koni yellows. Are there any issues i should be concerned with running the soft stock springs with the larger diameter bar?

 

I have not run a setup like that before, but if the springs are really soft then you would have to worry about body roll. I had those sway bars on my car at one time and i loved them, i also was runnin tein ha's too but still. If you are worried about something like that, go for your springs next, then get your sways. You should not need to worry about doing certain mods to your car. The eibach pro kits is pretty good from what i have heard, and i think it is like 160 or a lil more. Do that and see how oyu like it
