Can i run BMR Adjustable "Race" control arms on the street also or are they strictly for race use?

 

You can use them on the street. Since they have no elastic bushings, they tend to get noisy as the rod ends start to wear. A control arm with a poly bushing on one end and a rod end on the other is a better compromise for a street car.

 

how long do they usually last before they start to wear?

 

I'm not sure, but I would quess weather would have some part to play in your question.

 

Do you already own them?
I wouldnt run them on the street if you put any decent amount of miles on it.
Now if it sits in the garage and comes out on friday and saturday night thats another story. But ya, as stated, they will wear quickly.

 

How quickly they wear is dependent on lots of things. And how much noise you can tolerate factors in too. I'd get UMI poly/rod arms and plan on replacing the rod ends once a year.
