Here's your previous thread on this subject.

As mentioned previously: if you are already at stock height,not recommended as negative camber is not your friend.

OK, Yes I posted this question in June 2017 Did not get much response, and what I did was very short and not very friendly. Yes I'm very new to the Covair hobby, not looking for anything for nothing. I have been working on and restoring cars for 45 years, and I don't know everything and don't pretend to. But I have always tried to do is help others with ether information, parts, or time.
I do enjoy reading the post and looking at other projects people have on this site, but from now on I won't be asking any questions. I figure things out on my own

To keep the Wheels Camber in spec.... Just Larger diameter tires is about all.

Last time I suggested HD springs.. from our Corvair Vendors.... their Ads are in the upper left of the page.....

Can you post some pics of your FC? One from side and one from rear... That will really help!

After 45 years of Restoring... you sure realize that more specifics are needed when asking questions like this..

Questions are good. That is 1 way we all learn. I suggest get ahold of Ken Hand. He has researched FC suspensions and has come up with parts/kits just for things like this. He did a nice presentation last year at the convention at the annual Corvanatics meeting.
I have questions for you Tony. Where are you located? Are you a Corsa member? Are you a member of the SIG Corvanatics?

This just talking out loud, but the only way I can see to raise the rear with out having camber issues (except larger wheels) would to put solid steel spacers between the rear crossmember and the body of the FC. It would require longer bolts to mount the crossmember to the body. Also the mounting of various engine linkages etc would have to be compensated due to the lower crossmember vs body.

It would raise the back of the FC, but you would not have any more ground clearance if that is your goal.

Correction: "positive" camber.

Most of the people on this forum are friendly, helpful and encouraging. Don't let a couple of jerks dissuade you from asking questions. Also, remember that most of the discussions on here are from sedan and coupe owners so sometimes the rare FC questions don't get as much attention.

If you want to swap out the rear suspension why not use LM Corvair parts? I've heard it's been done.
You could also just make some adjustable front transmission mounts to have camber adjustment.

True. I didn't want the FC guys to feel like their posts don't get enough attention.
I'll try to be helpful with what I'm guessing is the original question.
If the springs are sagged and you are attempting to correct the ride height and camber the easy way out is to use some twist in spring helper nuts

Rubber ones are also available.

But much better to replace the springs. And Matt, heavy duty springs will not raise the rear but will lower it slightly. I have a set that is practically new if anyone is interested.

I know that about cars springs.... but I remember people reporting excessive Positive camber with HD's in FC rear...

I can attest to that! About 15 years ago (good god has it been that longeye popping smiley!) I bought a set of HD springs for my 63 rampside. Front turned out fine but it jacked the back up so high it cambered in the rear wheels and made it super scary to drive with no load. I took them out the next weekend and put my old ones back in.

As you have figured out - raising the rear of a Forward Control is a foreign idea to Corvair people.

As you might have derived, the modification of a swing axle suspension ( especially with an engine attached) has undesired consequences concerning suspension geometry - and its correctly functioning.

Rather than just stating you want to raise the rear, you might add what (perceived) problem you are trying to solve?

Or, what your end use is? Leveling the stance? A swamp buggy?

To me, the only way to raise the rear 2" is to build a 2" sub frame with all the mounting positions moved to the sub frame.

If you are looking for stance, I think people use new coil springs - and possibly cut a coil(?) from the front spring.

I think there are a couple threads here on the subject and a few people have performed the modification.

To bring ride height back up to stock (assuming sagged springs), of course you can get new springs but another approach is to place thicker spring seats (rubber) under the spring. These come in various thicknesses between about 3/8" and 1". Their effect is slightly more than their thickness.

Too much lift and the swing axles will provide unwanted positive camber, which has a negative effect on handling.

If that isn't enough, a taller tire will help a bit too.
