The ST stands for STREET CLUTCH! The thing that separates this clutch from the competition is TWO SPRUNG discs in the organic version clutch. These sprung discs help to dampen harmonics, and quiet the overall manual transmission driving experience. This is why most OEM cars clutch discs are sprung. This feature makes it the most friendly street twin disc ever. Sprung discs not only soften the initial hit when starting out from a stop, but also dampen noise while driving. They also help dampen engine to transmission noise during lugging conditions.
These clutches come with two pressure plate spring options that will change the clamping power. The standard "grey" spring is what the guys with big power street cars will want. The daily driver "orange" spring offers a 30% reduction in pedal effort over the gray spring but also reduces torque capacity by about 25%. Both organic and cerametallic clutches have these options.
The ST-215 features a BILLET pressure plate with heavy duty strapped floater, which also helps to decrease chatter. Compare this clutch to some of the other overseas stamped steel options out there and you can not beat it for the price!
The quality / value on these clutches is unbeatable. They are fully billet, no stamped steel overseas stuff on these clutches! The parts are 100% MADE IN THE USA!

- Organic Sprung disc with "Daily Driver" orange spring
