Hey Matt, do you have the insight or hf ones?

how much of that is rotational mass? rotational mass is what multiplies in value.

reduced unsprung weight is just better for handling but an equal reduction in sprung weight is just as good for fuel efficiency.

rear discs isnt blasphemy when your rears dont lock up as easy without abs.

I meant blasphemous in the "why upgrade and add weight when you can decrease weight" mentality of RPR. Personally, after several drum/disk brake jobs, I'd swap disks too to avoid the hassle of changing shoes vs. pads. It's sometimes a breeze, other times ridiculously frustrating.
