It's not much of an issue with the plugs, well no more than with shorties. The problem lies in the starter more than plugs, They wrap around the starter so it gets REALLY hot i had trouble keeping a starter in my car, so i went with shorties, power loss was TINY and i gained more torque so i'm happy with it. As for the braces someone else can chime in i'm not sure but i've never heard of anyone having problems with them.
