Ok, I am kind of debating on getting rid of the TRD coilovers and getting some Tein SSP's. I am curious though as to whether you use the stock suspension mounts with these or if those are discarded completely. It looks like on the install I read that the person who wrote up the install did away with the stock suspension mounts, or the black thing that the coilover assembly goes into while the suspension mount and coilover assembly mount to the car. Does that make sense? Can anyone shed some light here. Thanks.
