im pretty sure the msp calipers are the same as a certain 626 caliper or a mazda6 caliper. which one i dont remember, but i know its not specific to the msp.
thats why you.... collect the coolant!
its just like changing oil people. you collect it in a container and take it to a proper disposal facility.
why is that so hard?
ive never had any WOT noise in any rpm. hell i hit the rev limiter like 12+ times at the track, always had the rpms above 4.5k
so i guess there was a different source of the sound.
