After a very long search I've finally found the stock spring ratings. Pretty useful when you are considering upgrading your suspension.
Please note that I haven't included "non-linear" or "progressive" springs (like the TTE/Eibach or H&R springs). However, I have heard from several sources that the TTE/Eibach have exactly the same (average) stiffness as stock, and the H&R are on average slightly softer that TRD Sportivo springs....
Personally, I have opted for the TRD Sportivo coil springs together with the TRD WayDo (KYB) 4-way adjustable struts and the results are FANTASTIC!
Enjoy! s:wink: :wink: s:wink:
