Try calling SSR or Signal Auto on the weights for your particular sizing, either can be helpful in getting the weights. If i remember right, they told me a while back that the fronts were like 24 lbs and the rears were like 26? lbs.
It was either the SSRs or i was considering Work wheels as an option too. But, i tried e-mailing work 2 times for wheel weights, and they never responded
