So i decided to install my front control arm prothan inserts and noticed zl1’s have the z28 control arms. That was a surprise to me. Z28 was stamped into the arm. I also put one bronze wheel on to check it out.
If anyone is wondering the weight of a factory zl1 rim with a tire and a race star 18x8” rim and tire. I weighed them for comparison.
Zl1 rim 61.8lbs
Race star 54.4lbs
