DO THE 300ZX (twin-turbo) breakes fit the z?

 

Don't know, but you probably mean "brakes"

 

I am sure they do. but check this site out
www.arizonazcar.com
they explain why you shouldn't use them. but of course they will tell you that if they are trying to sell a product

 

i would say no. completely different specs, size and application. heck completly different cars altogether.

 

you could easily make them fit so long as they have the same number of bolts on the rotors. . but are they even better than the stock brakes?

 

300zx = 11", four-piston discs in front and 11.7", two-piston discs in the rear.

350z = 12.6" x 1.10" vented front discs and 12.1" x 0.63" vented rear discs.

350z brembo = 4-piston caliper with 12.8" x 1.18" vented front discs and 2-piston caliper with 12.7" x 0.87" vented rear discs


So the non-brembo models don't have 4-piston calipers.
