So i just installed this aftermarket momo steering wheel. I believe hicas won't be activating now.
The question here is do i still need a hicas elimination bar to stop rear wheels from steering?

 

swapping out the steering wheel has nothing to do with the hicas system.
and yes if u want to keep the hicas system from functioning you'll have to disable it and install an elimination bar.

 

Wrong, Riz. The Super HICAS system requires input from the steering wheel, and aftermarket steering wheels don't provide this input. Not only does the HICAS system need to know which direction you're turning the wheel, but what makes that system unique is that it considers how rapidly you're turning the wheels, so that it can handle the rear wheels appropriately for defensive maneuvering.

Why do a HICAS eliminator bar if you've already disabled it by changing the steering wheel? Department of Redundancy Department is looking for new hires...

 

Excuse me ?

 

Your aftermarket steering wheel already disable HICAS... why are you asking about installing a device that disables a component that was already disabled? That's called redundant.
