i did, i just karate chopped it in half.
actually you need to set the collar locks to fit completely flush -0.5mm with the bar on both sides. ive not had the bushing push out since. but ive not tracked the car so dont know how well it hold ups on a road course.
that said, if you only want the front bar, i suggest you get the stillen swaybar set and just use the front bar + stock bushings and clamps.
