Here are the NF210 Springs that are to be tested on the Prius.

As you can see, this NF210 is a linear-rate spring.

Below, you can see the new Sustec Tower Bar that's to be test-fitted.

The endplates are high-quality, high-rigidity pieces.

Next is the Medalion Touring Exhaust System.

... followed by the Concept G Exhaust System

The Sustec Under Brace is a 2-Point bar that braces the transmission tunnel.

First on the menu is this 2010 Toyota Prius. This R&D Session, we're testing DF210 Springs and NF210 Springs, as well as the Sustec Under Brace and Tower Bar. Before we start installing the prototype springs, it's important to take photos & measurements of the car at stock height. That way, we can easily compare the ride heights in relationship to the original stance.
