[Shotimes] my 89 SHO Sr 72 update

-----------------------------

BTW I didn't do all the math below, but if you tally up the 96 set up,
the12.2" 4 pot wilwoods come in about 30 lbs lighter total, 20 of that in
caliper/bracket, and about 10 in rotor (driveline rotational weight) but all
30 is unsprung.

30 lbs is a lot!!!

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
actually1 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 :o)

89 - another 7 lbs lighter!
