I did a search and not a lot of info, some swear by it, but when I asked Rich (GT Guys) he said it only reduced the throw by 15% and increased the shift effort. I put one in my NSX and it reduced the throw by about a third and there was no increase in shift effort, which made it a no brainer. I'm really loving the car, the shift is a little long, but the effort is so nice and easy. Just thought I'd throw it up there for those that have made the mod, and love it, and those that made the change and don't think it's worth it, please post up your impressions, I'm still on the fence!!!!
