What size disc rotor ?

[vpittman]

I've got a '73 cuda, gonna make it a daily diver, but still with a bit of performance. It currently has disc front and drum rear brakes with 14" wheels. I want to upgrade the rear to disc and rebuild the front.  The suspension is shot so I have to replace all that anyway, and since I'm under there...

If I go with 15" wheels, what size front and rear disc rotors should I go with ? Any suggestions on what brand ?

Thanks !

Upgrade the fronts to the larger rotors.  I question why people put discs on the rear, it does look cool, but that's a lot of money.

I have those brakes on the nose of mine. They work out alright. As far as rear discs, I will be doing that to mine for the cool factor. they work a bit better, and are less likely to lockup in moderate/hard braking like drums. Also they'd look killer behind my 18s

I would think the money is better spent going to larger discs on the front.  I bet the rear discs aren't needed until you go to at least 13 or 14" discs up front.
