from what i have read, if you are running a large RSB, 25mm and up, you should either reinforce the control arm, but only if you do not have really stiff springs. when you have softer springs like eibachs thats when you will see an issue. now i have had a steeda rear bar (28.6mm) for 6 months or more now, and i have seen no issues with it and the control arm, i went with stock end links tho so that way it doesnt put as much stress on the contrl arm being such a big bar. i wouldnt imagine you would experience much issue with a 25
