BMR Swaybar Problems On Track (Solved)

After seeing @Badmojo post on a Facebook group that he had the same issue with his BMR Front Swaybar bushings while tracking his car, I decided I should make this post. I think I have a good solution finally, but I will tell the woes of the story.

First of all, I love the BMR swaybars and how they have transitioned the handling and body roll of my car on the track. My buddy @LS6Larry actually had this same issue before me and we had been trying to figure out a solution. His is the pic of the red bar, mine is the black hammertone bar.

When tracking the car hard the BMR Front swaybar bushings can not handle the forces due to the much narrower bushing bracket and the bushings split after a few track days. I myself have split 2 of BMRs poly bushings and 1 GM truck rubber bushing that was a good fit. The rubber truck bushing lasted longer than the BMR poly, but it was still obviously a problem. The passenger bushing is always the one that split for us running CW tracks. (Not sure about @Badmojo)

When comparing the BMR bushings and brackets to the stock pieces you will notice how wide the stock components are for better load distribution. I tried to remove the stock bushings from the bar, but they cannot be removed. Looking at the stock brackets I got the idea to modify the BMR bushings by cutting off the protruding edges and have them fit inside the recess of the stock brackets. Everything mounted up fine the first time, but when i went to the track i heard the dreaded rattle of the swaybar again and thought it failed. When i got home i found it didn't fail, but the bushing stop on the BMR bar was too large in diameter and was rubbing on the stock bracket. With some crude grinding work while the bar was still on the car I think I have effectively come up with a solution to the problem. I have a TNiA Wednesday if the rain holds off to test this again.

Edited to clarify that I have never had a problem with the rear swaybar bushings.
