I have a set of the leather Ronins that I havent had a chance to put in yet. They are very well made, but they dont have any ass time yet so I cant comment on durability. The 'universal sliders' are bacically part of the seat, no problems with those. The only pain in the ass is you have to get DSM-specific brackets to bolt them down to the floor. I got a set of Weapon R brackets and Im going to have to modify them a bit to line up with the mounting holes on the seats.

I like the fact that they are real leather, all black, and pretty much direct copies of the Recaro SRD seats without any of the gay logos a lot of the knock off seats have. Also, a little birdie told me that if you catch Street Imports at a show, they sell the pair at a SIGNIFICANT distount as a 'show special'.
