yeah, i've locked up the back 2 different times on the street with this set up on the old axle ... once the lady didn't actually pull out, once the TJ ate a VW. i can still stop significantly shorter with lock-up then i could with too little pressure, this is why i wish i could get a middle ground caliper piston size. the difference is massive, 2.5x the area. and even though the stock single has more, the big dual is supposed to stop better still due to even pressure.

Total piston area:
Stock D52 ----- 6.78
front wilwood -- 6.28
Rear wilwood -- 2.46

part of me is thinking about taking apart these small wilwoods, having them machined bigger, and making a custom piston ... but that's not really priority.

EDIT:
Total piston area:
Cadillac ('76 -'78) Eldorado E-brake Calipers -- 4.55

EDIT V2:
Total piston area:
79-85 K20 JB7 front calipers -- 7.82 (metric banjo)

Edit again:
GM 1-ton caliper -- 8.90
