We anticipated this question and below is our response.
The cable height of our shift arm is only 3/16" (see pictures below) higher than the OEM. This is well within the safe articulation range of the cable. We have no personal experience with the Breedt arm so, I cannot comment on the difference with it. We do know several people with the Breedt arm that have never had any issues.
It's our opinion that there is no real issue with the Breedt arm. We do however believe many of the issues people are experiencing with it and other adapters are two fold. First, the method used to remove the cable from the OEM arm is one. Prying it off with a screw driver often leads to damaging the tabs that secure it to the mounting stud. Also, the use of the needless replacement bushing is a major contributor to the problems people are having with the Breedt arm or any arm or adapter. Removing the factory cable end and replacing it with a replacement bushing should NEVER be done. The cushion and subsequent play in the OEM cable end is there for a reason.
There is some validity to the issues people are having with adapters that mount on top of the OEM arm that significantly raise the cable height. This is one of the main reasons we went with a complete arm.
The OEM cable should be removed properly by depressing the center with a tool such as a philps head screw driver while lifting the cable off, either by hand or with a flat head screw driver. This procedure properly spreads the tabs inside the cup and releases the cable without force.
We have thoroughly test our arm and have never had any issues. Typical test setup consisted of the arm with varying counter weight configurations, solid shifter base bushings, solid cable mounting bracket bushings and a heavy shift knob.
Cable height differences...
OEM is at 1-5/16"
JBR is at 1.5"
The cable should only be removed using this method...
