73 Dart front Hub to Hub measurements ??
Yes but keep in mind, that is hub face to hub face
Right. But the track width shouldn't be very different? The offset on the stock rims is only +6mm, tires are centered on the rims, so, the track width should only be about 12mm = .47" different from the hub face to hub face distance. Alignment plays a small role, but given the factory alignment specs it should be negligible. Unless I'm forgetting something that's all that would change from the track width to the hub width, wheel offset (from the centerline of the wheel), the camber angle, and if they did the track width incorrectly the toe. But again, those should all be small differences on a factory car. Call it a 1/2" for the offset, 1/8" for the toe, pretty much nil for the camber on a stock car, so like 60"-ish.
The ride height is probably a bigger difference than any of those, the closer the LCA gets to parallel with the ground the wider the track will be. But that changes the hub to hub too, which is why I asked about the suspension being loaded or not. Lowered cars will have a wider track than a car at factory ride height. I haven't physically measured the hub to hub on my car, but it calculates to about 61", correcting back from the toe plate measurement.
All I'm saying is, I would expect a 73+ disk car to be a lot more like 59" to 60". A hub to hub of 57.5" is less than a SBP brake set up.
