I just installed a new set of BMR a arms with the spring pockets. Everything else on the front end was on the car before doing this swap, Same Eibach lowering springs and struts. when I got finished with install my car sits 1.5" lower in front than before. I followed their instructions for the install.
Has anyone else noticed this ? I didn"t think a arms would change my ride height.
Thanks

 

Our A-arms are manufactured to have no ride height difference -vs- stock unless you go with the tall ball joint in the lower A-arm. I'm not 100% but i don't believe Bmr's arms have any lowering built into them. As long as the spring is clocked correctly in them there should be no difference in ride height as long as your using a factory height ball joint.

Is it possible your front springs were not clocked properly before the BMR change?

 

can you possibly explain the tall ball joints? or provide part numbers? this interests me greatly.

 

We do a lot of tall ball joints with the A-Body platform.
Not really sure if anybody does anything like that with the 3rd Gen.
Maybe someone will chime in on it.But here's the theory behind them with upper and lower A-arms.

the ½" taller ball joint in the upper A-arm creates up to one additional degree negative camber at full bump travel.


The 1/2" taller lower ball joint lowers the car 1/2", adds 1/2" of spindle height and helps correct bump steer

I put in direct replacement MOOG ball joints. I know the springs are clocked correctly, I don't want to believe it but it's possible they were clocked wrong in factory a arms. I have used these springs in 2 87 Camaro's. The first was my coupe that I took everything off to install in this Z28, the whole suspension, rear end and motor and trans. From the top of the fender wheel opening to the floor was 26 1/2 to 27", I now sit at 25". I like the new stance, I am just trying to figure out why.


Thanks

 

putting a taller ball joint in the lower arm is pretty popular in a 3rd Gen application as well, usually 1/2 to 3/4 taller depending on availability.

 

Phil, We actually have lowers with the tall ball joints, we just haven't listed them yet. Do you see a lot of 3rd gen cars using them?

 

There are quite a few people here who use them, and a handful of people I've run into over the years run them too now. I think a lot of people are unaware of what they are and even of their availability, I think with some spreading of information more people would be interested I these balljoints in aftermarket and stock a arms.


everybody knows what lowering springs are and even drop spindles are a more common key word, but tall balljoints are still a bit more unheard of.

 

Agreed! We have these in stock and I am going to start working on listing and advertising as well as educating on them. Thanks Phil.

 

Omg this! I finally found an answer to my problem! Right before i was planning on purchasing two sets of springs to lower the car just right
