I might be able to get my hands on a set and was wondering about weight savings and possible track width change.

This would be for my '73 Dart.
I'm currently running stock '73 C-body 11.75" rotors, 2.75" dia. calipers and b-body adapters, but I might want to get something a bit lighter.

Track width is usually a problem on Darts as tire/fender clearance limits one from lowering the front end.

I actually 'gained' tire clearance because the C-body discs are positioned a tad more inward than the stock Dart discbrakes.

The added rotor diameter might help brakeforce but not by much I think.
