We appreciate you looking at UMI.
It's pretty easy for a company like us to buy springs in bulk and label them. One phone call and BOOM, new springs are ready to roll.
On the other hand, it's time consuming and more expensive to do it our way. We design our springs in house by buying prototypes made to our specification and testing on our actual cars. If the rate isn't quite right or the height isn't where we want it, we do another prototype set. This makes it take a year to introduce a kit instead of a month.
We know our rates and materials because we designed them. It's to the point where we can even trace the batch of wire the springs were made from (not that we would need to, but our winder has that capability). At one point in our development process we even changed the rear spring material to the next higher grade to ensure no sag.
This summer we will be testing our Green Machine a few thousand laps across the east coast to make sure the springs work great. The rears already have a season on them with no ride height change.
