Why I don't recommend suspension bolts:
#1 it's unsafe. the soft metal used in ring terminals is not rated with the same sheer strength as the suspension bolts. you're reducing the strength of that bolt, which is just dangerous.
#2 it's shortening the usable life of the vehicle. when you sand away paint you will introduce rust. rust at the suspension bolt means at some point in the near future you're further weakening that critical part of the car. when that rusts out, no one will want the vehicle.
#3 it's a poor ground point. it is a separate piece that is welded to the body. you're introducing a current path through the suspension components. who knows what that current will do to the gas inside the actual strut. it's a longer path, through more welds and connections, than the frame (which is right below the battery).
i see it again and again on this forum. it scares me that you're doing this to your vehicles. i wouldn't buy a vehicle where someone did that, nor would i want to ride in it. you've introduced a failure point into a very important piece of the vehicle.
when you sand for a ground, mask the area off first, mask off just larger than the ring terminal. so you only remove paint where you are grounding. then seal the ground connection (on both sides) with dielectric grease or silicone.
Ideal Big 3 Ground Locations:
Battery to Frame
Engine Block to Frame
My 2001 Accord
2005 Scion tC
frame ground location
engine block ground location
installed, grade 8 bolts used for grounds with silicone over the frame termination
terminated on battery
