I have both of these clutches for sale. Both of these clutches are for an R32 GTR. I am asking $700 for each clutch. The Tilton twin disk is fairly new has plenty of material on the friction plate. The OS Giken clutch originally came in a buddys GTR and he drove it perfectly fine no slipping. OS Giken does have a little bit more wear. He drove with this clutch across town and three states. If you have any questions please let me know.
