Can be used to lower street driven car

Used these with 9.5" coil springs to lower street driven car at a lower price than lowering springs. A big plus is they can be adjusted to exactly the ride height you want.

great testing tool

I run these on a metric car (street stock). they were a little to tall to start with, I cut them down to fit in. after that they were great.

As it turned out I didn't have to in stall the spring shim. I ordered this product it looked like it would be a better way to get the ride height over using a rubber shim.

It would be nice if a second threaded flange was provided to lock against each another. I'm not sure the adjustment could change over time from vibrations, but it would be nice to be able the lock the flange in place.
