Hi Bill,
Try Moroso wheel studs. They may have 4" long by 1/2". Attached is a link for
studs. I see a stud on the list that is 4 11/32" long but may not work. Item
# 46140. I bought studs for the ITB Alfa from this guy, but only 3" long.
Grade 8 bolts can work, just drop a tack weld on the back to prevent the stud
from turning. Have you considered different wheel offsets? You may be able to
achieve your maximum track with a slightly different offset. Kosei make wheels
with different offsets and come as a blank. You would have to have the stud
holes drilled out by a machine shop. You have to ask for the blanks as they
don't advertise.
Why did you choose to run a flex pipe thru the chassis? Why not a straight
pipe? My father welded a 3" pipe thru the cross member. You knew my father,
did he have too many Black Label Beers when he did this? Or is the flex pipe a
modern design that works better?
