In the next couple of months I going to replace my whole suspension and steering parts (most of them are original parts going bad) but everytime I see suspension kits they ask if I want a 1/4" or 1" insulator. I was trying to find out what the difference is between them and what they are for. Which should I use for street/applications. Here is the link of the suspension kit I was going to get and other parts.
