Getting ready to help a friend stud his Viper with Stud boy 1.187's. What are you guy's running in them. They look like they stick up about 1/2" ,which is on the long side. Here's why I'm a bit concerned. On my S/D track(.880) they don't sem to stick up as far. Aren't Yammi tracks .91 which would be a taller lug? Or does Yamaha measure thier tracks differently? Thanks for any imput, Butch.

Also, does anyone have a good clutch set-up for studded stock Viper?

I believe the track on the viper is .98 so your friend should go with 1.075s ,the yokohama track are junk and dont take well to to much stress from my experience. Also my friend runs a Maxium clutch kit on his works good.
