I buy all my steel wheels from "The Wheel Smith" in Ca. He knows the rules for LSR... the wheels are fully 360 degree welded, he also has my 15" Mooneyes Jig and can weld the tabs on for you. He can do 5" to 10" Smoothies for you,,, I would have him do the full 360 weld and tabs,,
Order the Moon Discs and Dzus Tab Kit from Mooneyes,, Tell Chico to ship them to Bob at The Wheel Smith.
(Bob Sage is the Owner... )
FYI - When I order my Wheels from Bob, they also have them powder coated for me. If you prefer you can save $30 per wheel and paint or powder coat yourself.
Hope this helps
Charles
