I think the lug bolt pattern will be an obstacle.

For '67-'73 the lug pattern is 5X5 inches. Plenty of GM mid and full size cars built with this lug pattern. Save the wheel hubs, just press the lugs/studs out and discard the used rotors and find some with the back spacing you need. You will most likely end up fab-ing new caliper mounts but you are going to want to go big on the calipers anyway, so all in a months work. Good luck and keep us posted on your progress. Check Wilwood as they have an assortment of hat depths and a choice in rotors. Maybe something will be close enough to work for you.

I'll get it now. What is the exact title? I called brembo and Wilwood. They both laughed at me.

With great respect for AndyF other than the caliper nothing else there will work(I don't think). Been awhile since I messed with these brain cells but for sure the Imperial used larger wheel bearings than the C bodies as well as different ball joints and if that was not enough I don't think you can get a Mopar Al Wilwood hub with enough meat on it to drill a 5x5 pattern. Now, if you don't mind running 4.5x5 in the front and 5x5 in the rear you might be able to fake it out and replace everything between the upper and lower arms in the front (might have to change the upper arm??) and then you would have "normal" C body brakes available to you. You would want to use late '72-'73 C body stuff, the non-Budd brakes. But then you are back with just factory brakes and still going to have to work hard to put something more/better/bigger together. Add a rear axle shaft and rear brakes swap out to the list if you want everything at 4.5x5. Check out Imperialclub.com and here http://www.imperialclub.com/Repair/Brakes/mike.htm for a Toyoda Supra brake rotor ideas. Still not big brakes but you might get some ideas.

Pick up a copy of my B-body book on Amazon and it will show you how to build a custom big brake kit. There are a lot of ocmponents available to pick from. Viper calipers would be an obvious choice but you could go with other OEM calipers or Baer if you want to go aftermarket.
And you just missed the sweet 3rd gen red Viper front calipers I was trying to get $265 for here. I sold em for $410 on the ebag.

As stated earlier, no front suspension parts are shared between the C bodies and the Imperials.
Guys need to remember that not only are the bolt patterns larger but the hub diameter and center register are larger as well.
Going larger on the brakes is easier on a 69 and earlier than my 72. His car uses a separate hub and rotor. The rotor itself bolts onto the back of the hub using a 5 x 4-1/2 bolt pattern. If he can find the proper offset rotor (like the old Supra mentioned above) he can simply bolt it on and go. Naturally, this does not address the caliper. That mount will have to be fabricated.
I haven't looked into it a great deal but I did scare up a 69 front hub to check things out.

Andy, those are good points but instead of going through all of that he can get the specs of a wheel he likes and search rotor sizes that will bolt to the back of his existing hub.
Much cheaper way to go.

That's the route I'm going to go with. A big brake kit from an aftermarket company. Using the stock hub. Viper calipers would be killer.

Remember that your biggest problem with wheel fitment will not be diameter. The fixed calipers with multiple pistons stick way out past the wheel mounting surface of the hub. In fact, the calipers on my hot rod stuck out farther than the lug studs. The back of the wheel has to poke in far enough to reach the hub while the spokes sweep outwards all the way to the rim of the wheel.
My Boyd Coddington Smoothie II wheels had to be cast with an extra 1-1/2" thick pad on the mounting surface. The centers were then welded into the rim and extra 1-1/2" farther out to make the backspacing work. That didn't give me much clearance but it worked.

My 69s had the 4 piston calipers.My 70s had singles.I know for sure my one 70 had a GM rotor on the front.It was there when I got the car and was still on 3 years later when I sold it.One of the hardest things to find especially on 70s is unbroken front turn lens.Seems they got broke a lot.I saved a set for my 70 and a set for my 69.Still wish I had the cars.Rocky
