Hi,

 

I recently purchased new rotors for my 300zx n/a import but they don't fit they sent me 28mm x 280mm front discs

and 16mm x 173mm rear discs but my rear discs are not vented they are solid.

 

I was hoping someone could explain to me why the rear discs are solid and why I'm having so much trouble finding the exact dimensions of the discs

even called Nissan for part numbers but they came back as TT discs.

 

many thanks.

rear discs should be vented like the fronts .. IE Vents inside between the 2 plates

 

regarding the front discs .. there are two sizes 26mm for NA 28mm for TT

NA and TT rear discs are the same size,

 

Paul

thanks for the replies

 

my rear discs are solid ?? could they be Q45 discs

you could of brought discs for the 300zx z31 .. they used single rotor on the back

they may have made a mistake like that is possible are the dimensions I posted for the rear discs correct for n/a import

 

thanks

that would be my guess aswel.

that would be my guess aswel.

 

Mine too....

 

...Rear discs on a Z32 are a slightly larger diameter to the fronts; and they are vented also. Both for NA and TT - rears are, as said, the same for both cars....

Thanks guys

I had a similar issue with my replacement front discs, and ended up replacing my calipers with turbo ones, it was just easier!
