i'm curious on what front brake rotors will fit the 77 GC210 skyline? i've hear that the 240z rotors will work, but would like to get this verified. Also...my GC210 has rear brake drums. Does anyone know what brake drums can I use of my GC210?

Get some accurate measurements.

Diameter of rotor, centre hole size, depth of 'hat' from back of rotor to wheel mounting face.

They MAY be the same as HGC210 (Oz market) in which case new rotors can be sourced from DBA, Brembo and others.

Rear drums - inside diameter, width of operating surface, depth of drum and diameter of centre hole.

I've heard of 240/260Z drums being used but suspect that offset is different so backing plate from 260Z would have to be adapted too.

I used finned drums on mine - had to modify the backing plate but it was fairly simple to do. Not sure if the upgrade would be worth it, but they're a fair bit lighter.

The Z finned aluminim drums are supposed to dissapate heat better and were a popular upgrade. There are also finned iron drums that are not as efficient as the aluminum ones, but better than the stock ones. I am going finned aluminum drums once I get the car back to Hawaii. If the C210 and C110 are similar, the drums should fit.

so if i wanted to upgrade my 1977 gc210 drums, what year/model should i look for in getting the z finned aluminum drums? 240z?260z?280zx?

My car's a Hakosuka, so I was going with 240Z. Lachlan's C110 is closer to yours, so maybe he could help.

Well, you can rule out the 280ZX as it had discs on the rear.

Mine were from a 240Z, which I had lying around anyway so I thought, "Why not?"

Like Art said, you need to measure some things and do some research to find out C210 is unfamiliar territory on these boards. Some of the guys at www.skylinesaustralia.com (Classic Skylines forum) may be able to help.

i joined up that forum but for some reason, i'm unable to post or reply to the topics. i sent a notification to the site admin, but i never hear from them...

Have a look in The Bible.

C110 and C210 use the same 11" discs. 240Z are almost the same, but not exactly.
