72 Pro Street Dart

I kinda just have to sum up the brake system for myself;

Front:

redrilled to 4.5" sbp pattern drum brake hub

1990 mazda rx7 turbo II front rotor

Willwood dynalite calipers mounted on custom brackets.

Rear:

Willwood dynalite calipers

2005 Nissan Maxima solid rear rotor

Aerospace components bracket

What about bearings and seals?

Any machining to anything,other than redrilling hubs?

This is looking like a really economical way to get 4 wheel disc brakes and a 4.5" bolt pattern!

I have sbp drum spindles etc..
U got it right, no other machining other than re drill the front hubs, in the rear i got axles from Moser Engineering so they are already 5 x 4.5 and yes i have to open the holes from the rear rotors to accommodate the 1/2 inch studs remember they are 12mm from factory, as my axles are custom made i order em with the hub centric to the Nissan size, but you can grab a die grinder and open the center hub a little is not that much of a difference.

the bearings on the rear are green bearings
