Do not use the extended bolts on the rear ! The additional length (even just 7mm) will likely protrude into the e-brake assembly and damage the spring attachments. In turn, this will cause the e-brake assembly to come apart and fall against the rotor. In addition to hearing an awful "dragging" sound, there will be a continuos clicking noise that will increase with speed . This is caused by the extended bolt constantly getting hung up on the spring attachments during each wheel rotation. Needless to say, I learned this from experience.
