MX5 high low absorber spring swap

My 1992 MX5 ride is not very comfortable  I have Cusco hi-low absorber on my car. I notice that the spring for the rear assembly is shorter, thus the harsher ride. So what I did is to take the from Cusco spring and put it at the back. Picture below (right to left) show MX5 OEM rear absorber/spring, rear cusco/front cusco spring, rear cusco absorber and original cusco rear spring, front cusco absorber and cusco front spring.
The result is: much improved and comfortable ride. What about the front? I put back the OEM spring and absorber for now until I found replacement cusco spring..
