Vented front discs / rear drum bias

[ivygreen65]

I've inherited a '74 260 and am in the process of getting it back on the road after about a 10 year hiatus. It won't be a track car, just one that will see some spirited street driving. I want vented rotors on the front, but I don't see a reason to put discs on the back. I vintage race a '65 Mustang and have to run a disc/drum combination, so I know that drum rears can provide all the braking that I'll need.

 

If I upgrade to Toyota 4 pots in the front with vented rotors, will I need to fit the car with an adjustable brake bias or will the stock valve be sufficient? I'm planning on putting a 280zx master cylinder on it.

 

Thanks in advance for the help.

I've got the vented/4runner setup with stock rear drums, and the bias is pretty decent right out of the box. Definitely suitable for spirited street use. I wouldn't bother with the 280zx master... my brakes feel great with the stock master.
