You can try Google Search "Stockton Wheel" here in Calif., they will do all most any backspace & diameter wheel rim combo you want, they can remove the hoops/outer rims & install new if necessary, if that's the centers you like, they may even have those centers possibly... call them they are in the phone book & on the web...
If you do that, wouldn't you end up with 5 1/4 back space?You might end up with a 5.5 BS and .25 inch spacer.
Don't know how they are these days, but several years ago a buddy used them and it took 3 times and they were still not right and had to use 3/8" spacers. The first time was way off, the second time they came back with Ford centers and the 3rd, we just made spacers and gave up.thank you Budnicks. I used Stockton for steel wheels in the past, but did not think to use them for one piece aluminum.
Yup. Wheel back space doesn't change but if you want less to the inside, add a spacer. No?To measure the B/S on a rim,set it face down and lay a flat bar accross the rim.Then take your measuring device and measure from the mounting surface to the flatbar.That's the backspace:grin:
Your Math is screwed up HEMI-ITIS, I'm with Cranky, A spacer places the wheel further away from the inside of the car, not towards it.
