Warning.. As I understand it, the NB shock mounts lower the car an inch or so. If you combine these with a lowering spring, you might be too low. When I inquired about these for use with my old style FM springs, he told me it would be too low unless I added spacers. I believe the new style FM springs are not as low so they work better with the NB mounts. Not sure about the height of the S-Tech.
