Hi Guys
I have a 67 camaro with one piece oem type rotors up front. I will be installing drum spindles and turned down hubs to be used with touring classics c5/c4 hybrid disc setup.

Will the front wheels move in or out? Just trying to figure out if the track width will change and by how much. Need to know what back spacing to order for frt wheels.

Thanks, Ray

Ray,
If you will use drum hubs they have 9/16" less offset than the rotors, but the 13" rotors have very thick hubs, just under 1/2" thick, so your wheels will only move in 1/16".

Thanks david! Thats good news. I can pretty much stick with the same back spacing I have working now.

my C4 front rotors were 1/4" thick, not 1/2" thick. that might affect wheel fitment if you are pushing things.
