DO NOT BUY! Magnum Farce 2" drop spindles are junk

I ran Magnumforce 2" drop spindles on my Challenger for years. And tens of thousands of miles.

They don't move the spindles any more than the 73+ disk spindles do. I have the same wheels on my Challenger now as I did with my Magnumforce drop spindles, no change in offset. I am running them with 11.75" Mopar rotors. Same set up with the drop spindles as with the 73+ spindles that are on the car now.

The wilwood disk set up is likely what makes most of the offset change. The change to 73+ disk brakes is more like 3/8". But that's not unique to Wilwood, a lot of the aftermarket disk kits change the offset in one direction or the other. The 13" Dr Diff kit on my Duster moved the track with out about 3/16", and that's in addition to the 73+ rotors.

At any rate, what size tire are you trying to run up front? Even with a 17x7" and 4.5" of backspacing, you should be able to get a 245/45/17 under there with the stock 73+ brakes. If you want to keep your rims, you should be able to ditch the Wilwoods and just go with the regular 10.8" mopar disks. If you want, I can even ship you a set of caliper brackets for those brakes. Free of charge. Then you'd just need rotors, calipers, and bearings.

***edit***

Sorry, I realized you're probably trying to run the Wilwoods to stay SBP. In which case, switching to BBP 73+ disks won't help.
