Wilwood kit vs Dr Diff Wilwood kit, help??

[Ozyduster]

I have the Wilwood fronts on my Charger. I love em. I’m running a 1972 A body MC with the 15/16” bore. No power. Brings my 4100# down from 122 mph nicely.

Never used the Dr. Diff. Stuff so I have no comparison.

I’m going to go right back to Wilwood for the same thing on the GTX.

Does the wilwood change the offset of the front wheels at all?

Their kits have changed over time. I think the one I was looking at most recently was something like an 1/8”

I am going to run Wilwood front brakes on the duster who has run the Wilwood kit and who ran the Dr diff kit as the Dr Diff kit uses a standard mopar rotor from a later 78 model car and uses custom steering knuckle as opposed to the Wilwood kit where it uses hubs etc to adapt the kit to standard steering knuckle

Any pros and cons between the two as similar price points

I don't know if it is true for '74 cars, but the 67-72 care drum knuckles and disc knuckles are different, and the 67-72 wilwood hub only fit the drum knuckles, because there wasn't much of market for swaping out the OE K-H disc brakes for Wilwoods.

Just a "buyer beware" to OP. The last time I checkled with Wilwood, which was about 10 years ago, the Wilwood hubs might not fit your knuckles if you currently have OE disc brakes. I don't know if it is true for '73s and newer, but for 67-72s, Wilwood only made hubs to fit the OE drum brake knuckles. Apparently, there were not enough potential customers who wanted to change out their OE disc brakes.

It looks like Dr. Diff's kit comes with or without new compatible knuckles

Oooh crossdrilled rotors .Kewl!
Does anyone hate crossdrilled rotors as much as I do?
Every race car I ever worked on with steel rotors and crossdrilled holes would run a very short duration & have micro cracks radiating from the holes. For this reason I prefer slotted w/no crossdrill & I'd be willing to bet you'd have to order them special, IF they'll even sell them that way.
But they look like you know what you're doing, so they're cool!
