The SE is the "Sport" edition and has stiffer struts than the SLE. If you want a softer ride, I'd be happy to send you my barely-used SLE struts in exchange for your SE struts!
There are no aftermarket struts or shocks for our cars - only COs (Coil-Overs) which are adjustable to lower your car and make it even stiffer.
I'm serious about my offer if you're interested. I have only a few thousand miles on my original SLE struts and the SE struts I currently have are getting worn out.
Cheers,
Jeff
