84-87 Cradle
I'm considering switching my 1990 Engine-Suspension Cradle to the Early C4 design in my Autocross offseason. So, what do we know about them ? Is the 84 an early design that was improved in the later years ? I I remember correctly the Z-51 Cars have some doubler plates to strengthen them. So, is there any one-year that's better than another? I know somebody who has a complete 84 front suspension I can get. Other than the weird Sway bar ( that I won't be using) Is there any reason I shouldn't use it. Not sure if its a Z-51 or not but I think about 50 percent were. I'm planning on doing some strengthening to it anyway.

I would think an '87 would be preferred and the '84 regardless of $$$ wouldn't even be considered. If it has the GM part # 14093126 on it I believe you could assume it's the latest version of the early C4 member. A later '86 and any '86 'vert should also have that GM#.
*** You could rule out any with these numbers I'd think: 14050090, 14044544 & 14093108

It will be a while till I can have a look but now that I have some part numbers, I have something to look for. Just because they think it's an 84 doesn't mean that it is. Thank You.

true. but for autox / racing, front is better. no loss of camber at high steering angle.

After watching the Video, it looks as though I might be opening up a can of worms. It looks as though the 86-87 Knuckles will accept my 1990 Wheel Speed Sensors. But will my 13-inch J55 Brake Calipers bolt up to the Knuckles ?

There are appropriate brackets for the J55 calipers.

I haven’t seen a set of those brackets in decades. You can probably find somebody to make a set, but it would be easier to just go to the C5 brakes.
I just don’t see the benefit for the average driver doing this swap to get to a Frankenstein setup.

but ..... if a person was insistent on it then I'd think @76LS1BIRD could provide either brackets. the OP can't use any of his '90 parts, shocks, spring and much other very different.
