Anyone running 300zx 30mm calipers on a 510?

Recommended Posts

Need help finding correct rotors for the 30mm calipers. I'm running a Infiniti m30 strut setup.

Redrilled 300z rotors seems like the most sensible option

I actually bought a pair of redrilled ones but were way too thick to fit in between the pads. Just wanted to see if possibly someone can send a link to a pair of rotors they're possibly running.

sell the 30mm calipers and get the 26mm calipers and put the matching rotor on from a 1990 n/a 300zx. Thats the setup I have on m30 struts,all bolt on.

That means something is wrong. They are called 30mm calipers because the rotor is 30mm thick. Measure your rotor. If its 30mm thick then you either already have 26mm calipers or you have pads that are too thick and need to be ground down or replaced.

 

You could easily have the same problem with 26mm units. They are interchangeable fit on THE EXACT SAME CAR. Swapping the whole kit out to 26mm will likely fix it because you are replacing the incorrect piece along with perfectly good pieces. Not Because the 26mm magically bolt up but the 30mm doesn't.

 

You can't have 30mm z32 calipers and 30mm z32 caliper brake pads and 30mm z32 rotors and not have them work together. One of those three HAS to incorrect.

 

Here's a site with fantastic z32 brake parts comparisons.

Find the problem, don't just throw money at it.

I have the 2 piston Z31 setup, but I'm also running S12 V6 struts with Z31 5 lug hubs. I have the matching rear disk setup in the back with a 15/16" MC and a Willwood proportioning valve. They seem to work well enough, but I have yet to test them hard enough to lock them up.

26mm calipers should be cheaper also.. because the 240sx guys want 30mm.. same with the z32 guys.
