I ran a RST 23 spline dual setup on the street and track behind 525+hp and it was perfect. I just took it out and it looks like I just bought it. Never slipped at all.

I'm probably going to sell that unit soon....because....

I just upgraded to an 18 spline setup and obviously needed a new clutch. I got a clutch with my purchase and I like it on the street so far, but haven't been to the track yet.

The RST should be good for the 800hp like they claim. Great clutch!
