@mark.
ive been experimenting with a steel wheel i had spare, ive always wanted banded steelies, minimum 7 inches.
done lots of research on the subject and done lots of practice welding,
anyway this is what i came up with, its the standard 5" steel cut in half, the center taken out and a 2 inch band welded in.
i did a few calculations on paper at roughly what i wanted the offset to be, i calculated an et+50 on the front would be best, as it is easier to measure from the front lip to the centre i calculated that the "front spacing" needed to be ~35mm.
so i pressed the center back in the now 7" wheel to get the 35mm, fitted the wheel back on and it looked like this
wasnt impressed, not enough pokey outy, thought, needs another 10mm, back in the press
press in another 10mm.
refit
alot better, could go another 5mm maybe, but ill blow a tyre on at some point and have another look.
right onto the rear, fitted the same 45mm front space wheel, looked lost in there.
oh that needs another 20mm at least i thought, anyways back in the press
out it came with a front spacing of 90mm
trial fitted that.
lookes better, again could possibly go a bit more, but ill blow on a tyre and re-evaluate at the weekend hopfully.
couple of pics of the 'dish' on the back one
the et's of the wheels in the pics are as follows,
front +39
rear+14
ill probably end up with something like,
front +35
rear +10
