Rear Crossmember

Post by MarkReidHRC » 09 Jan 2018 18:05

Restoring a 72 4dr 510 and going to install the Byron brackets.
My question is if I am planning to lower the car why would I not re/re the outer bracket also? I know the instructions say that the outer bracket stays and you weld on the new Byron bracket. Why not install both of them 1" higher on the cross member? Wouldn't this help eliminate some of the camber when lowering the car?

You can't use Byron's brackets set 1" high than their intended design unless you do some cutting and grinding on them and why would you want to after spending the cash? Best bet is a Penultimate crossmember where all brackets are set higher.

Yes, I understand you would have to modify the Byron brackets. If you go with the Penultimate cross member how do you get the toe adjustment that the Byron bracket offers?

By adjusting the inner pivots in or out on the threaded piece, no?
The IDx 10 concept is based on the 510 in the same way that the urinating I was doing last night was based on a 30 yr old single-malt scotch.

Not really sure. Doesn't seem like it would work though. A lot of force on the bracket and bolt?

Inner or outer I believe by placing shims between the bracket and the crossmember. Both inner and outer brackets swivel which is a really great feature especially if your running poly swing arm bushings.

So if you need to make a toe adjustment you would need to slip a "U" shaped shim in? The bolt in the middle of the brackets has the advantage of swiveling but may flex and fatigue over time as it is not connected in the corners. Maybe over thinking this. Thanks for your comments.
