z32 na vs tt calipers and rotors. please help

[coupe4me]

I am doing a 5 lug conversion on my s13, I cant find the tt brakes yet so I figue I can use the na for now. Can anyone tell me the specific differences between the two. I know that the tt are 4 piston calipes but thats about it. I need to know the rotor and caliper size and measurements. I greatly appreciate any help I can get, Thank you in advance.

Also does any know what brake lines to use on the rear to use the z32 brakes on my s13.

The only difference in size is that early 1990 NAs had thinner rotors & calipers. The calipers also were changed from Aluminum to Iron to reduce warping in 92 or 93, IIRC. Other than the early NAs mentioned above, the calipers and rotors are the same between NAs and TTs.
