All I can say is amazing. They perform almost the same as the HA. Only difference is the SSP is more forgiving on rough roads, but when pushed they are the same. Of course the SSP's are stiff, maybe too stiff for some with the more than aggressive spring rates and upper mounts compared to Jic, Tanabe, and TRD
. For me it's perfect. The body roll just seems more amplified than stock and seemed that way with the HA's. Some Hotchkis anti-roll bars should cure that. (Yeah I'm old school, it's still anti-roll bars for me). If there was an issue with the EDFC fitting, don't even worry (I will take pics). The kit even comes with adjustable endlinks for the front which are far superior to the stock crap. This allows for tension to be put on the front sway bar to accommodate for weight in the drivers seat or passenger or whatever. I have been playing with it. The SSP dampers are even shorter in length than the HA which were shorter than stock. It seems Tein just cut away the helper spring section and now you have the SSP. The back dampers of the SSP being a ridiculous amount shorter than stock. I will try to take pics of everything. Everything is on my car, but when my wheels come in I will take pics of the dampers. All I can say is I'm very happy I purchased them. Well worth the money.
