I'm not sure what you're going for. Tein makes a great coilover for our cars. The SS-P can be found for $1250 or maybe under that's the only configuration that will work with the EDFC. If you're into changing damping on the fly or want an electronic device that actually does something (1/2 din) and also for show. Then it can't be beat. Ripping out the back trunk plastics everytime you need to change or experiment things is a hassle. The EDFC does this changing for you in the seat. Now for that money. If your into auto-X or racing I would invest that money into JIC. Look here... JIC FLT A2
. Their quality is amazing. If the FLT isn't enough you can always get the FLT A2 RS where they custom tune the AS to your needs. I'm sure Tein will do the same and the EDFC is in high demand. I'm thinking of either changing to Jic or the SS-P and the EDFC myself. I'm sure you will be more than satisfied if you went with Tein and the EDFC.
