Actually weight is something I didn't even mention. Those Toyota
calipers are giant lumps of iron. The Volvos aren't quite so heavy.
For prepared, Wilwood makes beautiful, REALLY lightweight calipers,
nice stuff!
For street use, I was really just clarifying for any newbies or other
misguided members that you can't just pop on the Volvo or Toyota
calipers and motor on. Both modifications involve thought and careful work
and the the stakes are high! Stock is simplest and in many ways probably
safest unless you are completely sure of your work.
If you know how to calculate typical and max operating pressures,
pedal ratio/master cyl size, are talented enough to properly build a
proper caliper bracket and plumbing, go for it. If not, I really would
reccomend some good pads and maybe some of the nice rotors out there!
Motor On,
