I am looking into restoring my vr4 what can I use to upgraded all the lines on the car
you mean like brake lines? I know 3sx sells steel braided lines for that
I am looking to replace the brake/fuel/power steering lines
I am pretty sure 3sx sells those. Not sure if these are what you are looking for.
