So I’m trying to finalize the spec of my 4S CT, and I’m set on a 4S instead of a turbo, but I’m having trouble with the brakes.
In most literature and posts where PCCBs are mentioned as saving weight they are being compared against the massive steel PSCBs which are undoubtedly super heavy.
The benefits of reducing unsprung and unsprung rotating mass are many, and I won’t relitigate them here, but for those of us who may want to optimize the spec of a 4S the choice is not obvious as to which will be lighter and more responsive. I’m thinking that the PCCBs are much bigger diameter, so they may actually come out as a negative for rotational inertia versus the 4S brakes (goes with radius squared).
Has anyone been able to source weights for each setup, especially broken out into disc and caliper weights?
