chassis help -
hey everyone
The other day when I was out - for some reason I seem to notice just how much the car seems to flex(?) going over our lovely roads. I wondered if there are ways to firm up an '85? I read somewhere 86 and up had a kit but not the 85. I did not know if there was anything reasonable that the avg to less than avg person could put on that would help. I thought about reaching out to a few shops but that could probably get a little expensive - plus I would need to find one I could trust.
Nothing urgent - but I feel like I would not be the only one that could benefit - I would think a lot of 84 and 85 people might take advantage.
anyone ever look into this or try anything?
thanks
Sean

Well, if you don't mind driving across 224 a ways, I will show you what I did to my car and take you for a ride so you can feel how I firmed it up. If it doesn't rain, Aug 2nd would be a great evening to do so. You could come over to the all Corvette cruise-in over here. I know it is a little bit of a drive, but it is basically 224 all the way.

This has been discussed in detail in other threads. If you tighten up the chassis in one place the flex will move elsewhere.

There's way too much flex in the chassis for an easy solution. It would require substantial modifications to make any real change in stiffening the chassis from what I have gathered.

that's a lot of stuff - I will need to re-read and maybe get an engineering degree or 2 -
recook - I came across a post or 2 of yours with a camber brace and harness bar - you seem to like that and it does not seem too intrusive?

the only issue with the harness brace is that you cannot open the little doors in the back, so you can't get the jack out. at this point my spare is 20 yrs old and not under the car. if I can find or build a spare tire delete bracket, it won't make a difference, plus I am thinking of hanging a transmission cooler with fan back there.

to retro fit the cross brace you need to fit nutserts into the chassis, so its a bit of stuffing around, but then any of the options involve a bit of stuffing around !

I would look at the Exotic Muscle harness bar - they tighten the rear up the 2 rear points and up into the seatbelt bolts in the halo

Also consider the C beam plates - if you can find some - they work

Have not heard of a C4 breaking in half yet, flex is something all vehicles have to varying degrees.
No flex means it will find a weak spot and crack leading to breakup, ever looked at a plane how much the wings flex
Forget about it, like that song goes don't worry be happy
