How big are the rotors on your F-Body?

I have 12" non-slotted/drilled rotors.

 

I'm running 12in.

LS1=12in
LT1=11in.

 

I'm pretty sure that an LT1 has 10.5" rotors on the front.

 

13" C5 rotors

 

3rd: 10.5 x 1.10" (F3)
ZR1: 13.0 x 1.10" (C4 & F3-1LE)

LT1: 11.0 x 1.26" (F4)
LS1: 11.9 x 1.26" (F4)
Z06: 12.8 x 1.26" (C5)
F55: 12.8 x 1.26" (C6) *2 pounds heavier than Z06
Z51: 13.4 x 1.26" (C6)

996: 13.0 x 1.34" (tt & GT3 Porsche)
