That got a 340?

Well then, I got a one of one,I guess.
I did have to offset the springs with the hanger business. And I narrowed the rear so I could run 4.5bs deepdish wheels. And I moved the axle back just a tad. And I had to center the rearend from side to side.
Then I went for a roadtest to see what would happen in the turns, and adjusted the inner walls of the tubs with a lil pounding. Then I lowered the car, and repeat until I could drive in traffic without rubbing. Then I lowered the pressure to 24psi, and repeat.
Looks real nice. Yes those 325s are in the wheelwells. Way up in there as high as I could put them without rubbing on that outter bulge. And I did not cut the lips either, altho I did bend them up just a little across the top.
Those 325s on 10s have a section width of 13.25 IIRC,(and about 27 tall) and the tubs are about 3/4" bigger, so there was just enough room. And because my springs are nearly flat, and the shocks are pretty stiff, there is very little body sway, and I can drive it normally. But I can't do any aggressive cornering.

Like I said ; "carefully"
In the end, it didn't much matter cuz the 325s have about ZERO more traction on the street than the 295s. The 367 wastes 'em same as 295s. But they sure look intimidating.In 2005ish bought a couple of sets of 295s in case they went obsolete. But they got so hard in the second summer, and she is no longer my DD so the first set of 295s are still on there, and sliding around predictably perfectly,lol.

295/60-15s you say? I might have to get me a pair. Fifteen years ago I didn't see those in the tire catalog.
