Max tire size - 68 dart

And there's a few more options for tires in 275/35/18 too. I know on my car I'm pretty close to having the same offset front and rear, but the B-body rear axle, body style, and brake choices play a role there. My rims are actually a +35 in the front and a +38 in the rear, and I'd be better off with a +35 in the rear. The 13" brakes and a 3mm spacer make my front offset 27mm effectively if you compare to a stock 73+ disk set up. It's certainly doable with the right combination especially if you're willing to consider a small spacer to make up any difference.

I think I have a plan, it's just when to pull the trigger. I want a couple hard runs, possibly through the local hills, to feel out the fronts and rears to see if they're still rubbing after it's bfh treatment. But if I pawn off my MP shackles and buy the Dr Diff shackle, I'll have offset shackles that will accept the aftermarket leaf springs and retain my 1" drop. Not only that, but it will center my 8 3/4 as mine favors the passenger side about 0.25". I was going to also borrow a buddies helper springs he had on his '72 Charger to help reduce compression. On the fronts, while it would be in the shop, I was thinking about upgrading torsion bars to something thicker than the 1.06" bars I have right now.

At that point, I could just remove my rear +5mm spacers and run the car as is. The only problem is I wouldn't really pass tech at any racing events as the front tires are cut up and the rear tires had their sidewalls rubbed away. But I could run the tires as is on the streets and just have fun.

Luckily, when I go to the tire upgrade, I don't think I'll be paying a pretty penny in wheels. I found out Summit still offers the offset I have up front. So, I could just buy 2 wheels for less than $400 and I have all 4 corners matching. The only thing I'm worried about is the section width. The Michelin's on an 18 x 9" are 10.2" wide. The Bridgestone RE-71R's are 10.9" on an 18 x 9.5" wheel. So, I'm hoping by having a wheel that's .5" shorter it would bring the section width down to about 10.6-7". Looking at RimsnTires.com, with my +5mm spacer on the back, I'll be the exact same distance to the fender as I am now and I think I'll be able to clear the springs. The loss in 0.4" in tire height may help me.
