Yes, there are. And thank you for reminding me because my Dart has them on it. They have two mounting holes for the spring eye, the higher one lowers the car about 1". Which is probably why my Dart doesn't sit as high the OP's car. Oops.:rolleyes:
They do change the spring geometry though, so you have to consider that if you're using the SS spring for the intended purpose of increasing launch grip.
