i've run JB6 and the small wilwood in the rear of a jeep, and JB6 and the 1-tons on the front of jeeps. never got my hands on the D52 JB7, and i'm really thinking next time i'd get the large wilwood for the front to try. my '55 is getting the 1-ton front and JB6 rear, but i'd also love to try the 76-78 cadi rear d52.
Total piston area (sqin):
Front:
JB6 D52 -- 6.78
wilwood dual -- 6.28
79-85 K20 JB7 -- 7.82 (metric banjo)
GM 1-ton (slide mount) -- 8.90
Rear:
wilwood dual -- 2.46
Cadillac ('76 -'78) Eldorado E-brake Calipers -- 4.55

I’ll be sure to post my impression when I get the truck back on the road. I have enough miles on it to make a valid comparison.
