hello, i bought rotors from some guy but they're too small. he said they were for a g35 but are there any difference in rotor size on different years?

 

03-04 Brembos, 03-04 non Brembos/05 Sedan AWD, and 05-06 Sedans/05-07 coupes are all different sizes. What car do you drive?

 

This should help you.

Your 2005 is supposed to have centric part numbers 42080 and 42088, the ones that you were sold were 42074 and 42077, smaller rotors.

how did you know? so what models are the rotors i have for?
thanks for your help everyone.

 

I knew because there are only two types of rotors he could have sold you. And you got the smaller ones, so I determined the parts from that. And I work for a brake company so I should know my inventory items and cars that I sell to

The rotors that you have are made for a 2003-2005 non Brembo 350Z and a 2002-2004 non Brembo G35 and 2005 AWD G35

man thats confusing, thanks for your help, appreciate it.

 

Yes it is confusing at times, next time you're in the market for rotors/pads and don't feel like dealing with getting the wrong parts, let me know, we keep parts for your car in stock, centric rotors, dba rotors, stoptech pads, hawk pads.
