OK, I’m curious as to why all of a sudden most of the 1/12th scale brands’ newest kits feature fixed kingpin front ends with no camber gain and no reactive caster. Are there any suspension engineers out there who can explain what might be the benefit of reverting to such a “primitive” design? To date I’ve built 4 of these newer cars (2 different brands) for other guys and none of their sliding steering blocks slid very smoothly no matter what oil, lube, grease, polish, or other prep I tried.
