Hi Guys,
Easy one for someone to answer hopefully. Internet searches have not beeen fruitfull.
I'm looking to do either an SR20T 280mm * 22mm sliding caliper brake upgrade or R32 280mm * 30mm with 4pot calipers upgrade on an S13 knuckle.
Just want to compare the unsprung weights becuase I have both sets of calipers and SR20T rotors but it's going on a 1000kg car so either setup with good pads will be enough brakes.
I need to know how much the R32 30mm rotors weigh so I can compare the two setups.
Interestingly I weighed the single piston SR20T calipers at 5kg ea and the 4 pot R32 calipers at 3.5kg ea on bathroom scales with a min increment of 0.5kg so weights are a little rough.
Surprised me, if the R32 30mm rotors aren't ridiculously heavier than the SR20T rotors (which I fear they are) they might still be a viable option.
The SR20T rotors weigh 6.75kg ea.
Thanks in advance!!!
