Jrlegacy23's 72 Dart Build, pro-touring style

Idaho said

Thanks for the helpful response. I also have an 8.8 4:10 posi waiting to be shortened, will relocate springs and tub or mini tub.

For the front, I just want to do whats needed to get the fender at tire top level or a smudge lower with an 18" wheel and rubber thats proportional to about the same profile (35) you've got. Not sure yet if I'll even need drop spindles.

Any reason you're not using up the tub space?

I am looking to do pretty much the same thing, I just have an infinity to new technology for some reason. I am goint o run the 275/35/20 (27.6' tall) in the rear and 245/40/18s (25.6' tall) in the front. This yields me the same amount of sidewall front/rear and still have a staggered look. This page helped me get dimensions, just pick your tire size and click specs. :

As for why I am not using the full potential, I minitubbed to get something a wider than a 7 or 8" tire in the back. I looked into a 12" wide wheel, which will fit and maximize the space in the minitub, but my wallet did not like the price of 12" wide wheels. 10" wide are much more common and a couple hundred cheaper per side.

If you like the torsion bar set up and want to go that route, there are a couple options for you. If you want handling with a drop look, I would run a Hotchkis (or similar) 1.03" torsion bar. You will get the handling from a stiffer bar and be a little lower to get the stance you want. If you do not care about the handling, and like the stock ride, then I would go with drop spindles. Just remember with the drop spindles, to clear the tire rod ends, you either have to run a 18" wheel or have less than 5.75" backspacing on 17" or smaller rim. The only thing that I would not do personally is run stock spindles and just turn the torsion bars way down, other wise the car will lean like a bastard around corners.
