My 06 EX sags and occasionaly bottoms-out over bumps when loaded (not overloaded). I am considering new rear springs and noticed the SI rears have a much higher spring rates.

Will swapping the EX for SI rear springs be a good choice, leaving everything else stock?
EX P/N: 2325360
SI P/N: 4886895

I do not want to lower my EX or create a poor handling Civic. This is a commuter which pulls duty as a kid+gear taxi on the weekend.

Thanks!

 

just get all 4 if your gonna do it. front and rear springs.

i happen to have a set. pm me if interested.

 

If you want to do this and need the suspension, let me know. I have a complete SI suspension (strings, dampeners and struts), with only about 10K miles on them. I will part with them very cheap.

 

so is the SI strut setup stiffer than the ex set up?
