Just so its stated, the tein flex is a slight softer ride than most other coilovers of the same price range. I personally have the D2s, and have ridden in a Del sol with the tein flex, and they still allowed more bodyroll than id like, while the D2s, i have kept me nice nad flat through turns. Its not as comfy on longer rides, but thats up to you.

But i agree with the man above, if you get some GOOD threaded body coilovers, with all independent adjustments (preload, height, dampning) you will be much better off with your setup than just springs and shocks that you MAY have dampning adjustability.
