How many Vettes were produced with the Z07 option '91-'95? Did it specifically include the J56 brake option as well as well as the ZR-1 suspension parts?

3935 C4 Z07

1991 733 coupes
1992 738 coupes
1993 824 coupes
1994 887 coupes
1995 753 coupes

Did it specifically include the J56 brake option
It included the J55 13" brakes, faster steering rack ,oil cooler
ZO7 was basically the available previously Z51 and FX3 packages combined together

Did it specifically include the ZR-1 suspension parts?
There are no ZR1 suspension parts

ZR1 had same suspension as regular ( with softer springs than Z07 pkg )

Spring rates '91
front rear
Z07 115.5 57.2
ZR-1 96.2 39.9

In later years the ZR1 had softer rear springs than base cars
