You will need a spacer to install this. Not much you can do to tune these unless you get an hptunner or power tunner. Why i recomend the progressive kit. Progressive kits have the knobs on the controller so you can taylor it to your car easier than a base kit. These kits realy help reduce kr on gtp. They should be one of the first few mods on em.
