Who has bmr k frame in here?

Just want to know if it’s true or not that you don’t need bump steer kit with the bmr k frame. Just want to know for reference

I am running one and no bump steer kit. Car was aligned with no issues.

Cool thanks. Yea once I lowered mine got bump steer. Was going to do the kit, then I read that the k frame will fix that

I have no idea if the BMR "K" will fix any bump steer problems or not. I do know that bump steer occurs as the wheels move vertically so since alignment is set at a static height you can have good toe on the alignment rack so long as the ride height is static, but it's possible to have bump steer once you move the front end up and down. You have to move the wheels through their full range of vertical movement [ while keeping the wheels straight ahead ] to measure bump steer.

My car is lowered on eibach pro-kit springs with the bmr k member and i dont have bump steer, even with the stock k member i never had it.

What year is your Mustang? I have a 2011 with BMR K-Member, radiator support and control arms and get the dreaded EPAS shudder due to the poly bushings on the control arms. Didn't have bad bump steer but running 275/35/20x10 up front made it worse. I improved it quite a bit since I installed the Proforged extended tie rods that are much beefier than stock and taller so the angle is improved.

2014. Not 100% but pretty sure the EPAS issue is only on the 11 or 11-12 cars IIRC.
