I installed 96 Extreme Max 1.15 studs with 96 Stud Boy 1.187 PowerPoints on my Vmax-4 last year. I've gone over 1000 trail miles with them. Don't have any bent or broken studs, none have pulled through. I paid $100 for 96 Extreme Max studs, nuts, and backer plates. Paid $125 for the Stud Boys and nuts, no backer plates. I'm very happy with the Extreme Max.
