The stud set came with instructions that made it very easy to install, and even mentioned what thread lock to use too. So start to finish it was an easy process.
Amazing quality and craftsmanship. These compliment my new Klutch Wheels SL5's perfectly with stronger solid studs and conical seats. The costs is worth knowing your wheels will stay on the car and have adjustment ability for security with a T40 for the stud and 19mm for the nut. Highly recommended.
