Kind of dealing with this in the future. I have the SPC front tensions and will be replacing the bushings with my Nismo's. As for the rear, they look a bit ready for replacement and I was wondering if the Nismo size was the same.
Disappointed to find here that they are too small. I'm guessing a machine shop would have to make and press in some bushings to 'shim up' the hole so that the Nismo bushings would work.
Let us know what you do or find out. I'll need that info in the coming time. Thanks, Vinnie
