Installing Steeda LCA Bearings

[DAVECS1]

Hey I never got notified of further posts! At any rate Eric, I agree with your statements 100 percent. I did not even notice the off axis pivot point until you said somenting. My gues is they are tying to regulat the car's instant center for weight transfer. Your point is well taken though, that design really makes the mounting point complicated.

As for a happy medium for IRS. If you want my honest opinion, the best ever made was the C4 corvette. I will go hide under a rock now :-)

I have delrin cradle bushings. The BMR cradle lockout. Boomba billet verticle links, and now the LCA bearings. This not handling related so much but I just added the GT350 halfshafts, As I snapped a stock one launching my car.

DAVECS1...Did you mean Cradle lockout or diff lockout? Looks like you have the BK048 like I do. Wondering if you have something on the diff. Touching the diff bushings seem to drive a ton of NVH on these cars.

Thanks for the clarification on where you posted. Super helpful info.

I did Delrin for the whole cradle including the diff. Then I installed the lockout as I liked the Frame tie in pieces for the cradle. I had to do some dremel work on the front cradle bushings. With the bushings alone, NVH was not much more noticeable. With the lockout, it became a bit more. I added the vertical link and did not notice anything. Then I added the half-shafts and LCA bearings, and that is when I began to notice spring and shock deficeincies

If the diff was left alone do you think NVH would be more tolerable?

I'll chime in. Doubt it.

I have the LCA bearing and I originally had BMR spherical vertical links. Tried Steeda vertical links (which are big delrin bushings) and objective harshness was made a moot point. I don't have the same differential work as the OP, but I'm pretty sure since the diff is really mounted independently of the rear suspension articulation, it won't matter.

I would say no also. When I first put the Delrin in it was not that big of deal NVHwise. Definitely the small amount of NVH was worth the huge handling gain.
