My "new" '74 Duster- or why I need a project like a hole in the head
Finally, let's get them on the car. In the back, in addition to my 1/2" spring offset, I took another 1/4" off of the quarter lip.
The front was a little more complicated. I added a set of Magnumforce tubular UCA's, which I had bought for the car awhile back and hadn't got around to. I also installed a 13" Cobra brake kit, courtesy of Dr. Diff. That added 3/16" to the track width, which worked with the 18x9's and 35mm offset. The center bores of the enkei's started at 73.1mm like a lot of rims, but necked down to 66mm, still not enough to clear the hubs. So I had my machinist open them up to clear the hubs.
While I was at it, I installed a new set of Hotchkis Fox shocks I picked up from another forum. Not the fancy new adjustable ones, but good enough for me. I also upgraded to FFI's 11/16" solid adjuster tie rods.
They do look nice...
Still working ride height a bit, and the alignment is just roughed, but here she is for now...
So the almost final verdict? The fit. No rubbing so far, but it is definitely close. About a 1/4 to the springs in the back, and no more than that to the cut down quarter lips. I dont think I could go much lower in the back without re-working the inner fender well a little, theres a bump that narrows the well not very far up.
Anyway, final specs-
Front: 275/35/18 on an 18x9 rim with 35mm offset (6.4 backspace). Dr. Diff 13 brake kit, so effective offset 30mm, effective backspace 6.2
Rear: 295/35/18 on an 18x10 rim, 38mm offset (7 backspace). 68-70 B body 8 3/4 (54 15/16 flange to flange) with 1/2 spring offset and 1/4 lip trim
