Some weights from the 12.2" TCE kit...
note, my scale isn't a $5000 accurate to .001 ounce deal, but I weighed the
stuff against the OEM pieces, so even if it's off in and of itself, the
relative weight differences (from OEM) will still probably be the same (or
very close).
10.1" stock rotor - 11 lbs
96 rotor - 15.5 lbs
89-92 oem front caliper (with pads) - 8.5 lbs
94/95 OEM caliper w/ bracket and pads - 14 lbs
4 piston wilwood caliper w/ TCE bracket and new pads - 5.5 lbs
12.2" rotor w/ alum hat - 10.5 lbs
So basically the wilwoods replacing the stock 89 rotors/caliper are actually
1 lb lighter in total rotational weight, and are about 6 lbs total lighter
than the stock 89-92 calipers (and 17 lb lighter than the 94/95 set-up, 96
should weight about the same, maybe a tad more for the slightly larger 96
caliper brackets and pads).
Only negative is the 12.2" rotors push the weight farther out the axle
centerline, so it's got more rotational centrifugal force, but I'll live
with that I guess. Total unsprung weight is still less.
I'm happy. Nothing worse than putting on an upgrade and having it weigh
more than the OEM part
