I just like vertical ball studs being an on road guy by nature. They allow much finer tuning of roll centers and camber gain. The thing I don't like about the Losi camber link locations are if you want to raise the inner camber link to lower the roll center, you also have to shorten it too which gives a lot more camber gain and raises the roll center again, pretty much canceling out the lowering effect of raising the location. (I bet that's confusing huh?
) So really all you're adjusting is the camber gain. Roll centers can be very useful when you're trying to fine tune a setup. Having the vertical ball stud on the caster block, you can raise your roll center by adding shims or lower the roll center by taking out shims under the ball stud. That's what I liked about the look of the Trinity rear hubs too.
