Hi,
Has anyone run a bmr K-member with the stock upper and lower control arms or at least the upper tubular and stock lower. I want to reduce the weight of my Z28 but think the tube a-arms are mostly for road racing?? please any input would be great.
Thanx

 

My friend is running his with the stock arms; I've got stock upper arms with poly bushings and tubular lower A arms. Both work fine. Great access for service!

 

Great, I was planing on running the K member with tubular upper a arms and stock lower arm.

 

When I changed mine I didn't see any real benefit in going with tubular upper A-Arms. The stock pieces are pretty good. The lower A-arms free up more weight and access.

 

So you have stock upper and tubular lower a-arms

 

Yes. I did install poly bushings on the stock upper A arms with new ball joints.
