im looking into buying some ws6 snowflake 15x8 wheels for my 84 grand prix. there is a complany that widens wheels and im going to have them at 2" to the width. 1' outside 1' inside so they will be a 10" wide wheel with 5.5" backspace. i have a 600 horsepower stroked 400 and i want to know if i can trust these wheels to handle the torque when i launch on the strip. the company stands behind their welding and machining so it could care less if their modifications break. i just want to be safe to know that 40 yr old cast aluminum will stay together.
