My brother has some 2 piece IMPUL's for his S14, and he took them apart to clean them up, polish them and repaint the center part of each wheel. There are 40 little bolts around the outside of the wheel that hold both pieces together. Both parts of the wheel and the bolts are aluminum while the nuts are steel. We just want to know what a safe amount of torque for these bolts so we dont strip anything or lose a wheel in the middle of a mad tyte drift or something.

thanks!
