Brake rotor sizes?

I tried to search this but I'm not getting the results I'm after. I need the diameters and thicknesses of these rotors:

LT1 front and rear
LS1 front and rear
ZR1 front
C5 front
ZO6 front

If anyone can help, I'd really be happy

im pretty sure the ls1 vettes have the same setup as the ls1 camaros. i have been told the z06 has some different stuff but have not looked into it.

Incorrect hehe

The LS1 F-Body has the same brakes as the C4 Vette.

The LS1 Vette (C5) has pressure cast PBR calipers. The F-Body has the gravity cast C4 style. Z06 is the same as the regular C5.

The C5/Z06 rotors are 12.8". Only difference between the 2 cars' brakes is the color of the caliper.

interesting. i cant imagine another inch on the rotors with 17 rims. after i put the 98 style camaro brakes on mine, the size difference between the 2 was pretty large.

This is a 13" rotor under a 17 inch rim.

I also have firehawk rims as you probably noticed. You're talking about the difference of an inch, its hard to notice.

you may say its the drugs....


but i noticed. The single piston cals looks small as hell, along with the small rotor.

Anyway, just a quick question, have you ever seen something like the gorilla locks for these wheels in black?

I was until the Wilwood install using the Gorilla chrome lugnuts. I know they sell a black chrome. I broke the key though (my fault) so I just haven't ordered a new key yet.
