We like both the TCK and RB studs, both are very well made.
The TCK studs has a rounded ends allowing quick start of the lug nuts and less likely chance of cross threading. Made from degassed, tumble blasted 4140 aircraft steel and coated with baked on dry film lubricant. I use these my personal car.
RB studs allow easy removal when you decide to go back to lug bolts. The typical allen drive(80-90% of them are that way) stud kits out there...you will never get those off without stripping them, then it's breaking out your Vise-grip and destroy your studs in the process.
You get what you pay for in wheel studs as well!
