Has anyone figured out a good leaf that can be made to fit an FC?

You could probably have one made by a spring company, however, you will need to supply them with all the proper dimensions. The 1964 FC differential has the mounting bosses just like the car differential. How you will attach it to the lower control arms, is going to need some fabrication work probably.

Have one made! or make it yourself...see U-tube

Remember... you'd want a '64 Diff case..but a '65 has bolts to hold a bracket...just no Speedo drive.

On cars.. Coils are 40% SOFTER and the leaf takes the rest of the load.

How about a Corvette spring? Use the long one and remove as many of the others as you want to for as much lift as you want.

I would guess a Corvette spring is too short also. I'll have to check.

Fabricate a Z-Bar.
Another critical component when adding this spring arrangement, to a greater degree given the FC's higher CG, would be a fairly stout front stabilizer bar.

I have to ask why are you considering the rear leaf spring on an FC? That will more focus the answers in the direction you want to go.

Don't know about the OP but I would do it for better handling.

For better handling add a front lower spoiler. And make sure your suspension parts
and alignment are all in good order.

And low profile tires, a large front sway bar as Jerry mentioned and faster steering and...

FC's are 4 turns factory... just add a smaller steering wheel.

That's still pretty slow. Shorter steering arms would help clearance with wide 16" wheels also.

The 1965 FC differential looks like the Late models, but it "Has" the Early speedometer drive on the side of the case and Early internals, just like other Fc's.

I have not seen any examples of a transverse spring mounted on the rear of a Corvair FC. But there were aftermarket stabilizer bar kits available. It my be easier to find one of these or make up one like I saw here on at least one post.

n general, I also feel that I can only expect so much handling from a brick. So Like Timothy said... Add a front air dam and tighten up mounts, bushings and correct the alignment. My Brier has performed quite well for more then the 300,000 miles I have personally driven it.

300K miles??? that's a long distance "procession" hot smiley

Why would you only consider one end of a vehicle?

Rear control arms from a '64 will fit FCs.

As other said - the FC front suspension is more critical. While adding a 64 car style leaf in back would limit axle jacking - you are still going to end up with the rear inside wheel in the air on a tight curve if the front suspension does not have a "heafty" sway bar.

Take a look at some of the autoX pic. FC front end is down low and rear is sky high.

The FC's were designed to ride well, and compared to the other FC vehicles back then they do ride well. If you want better handling, you'll have to install shorter and stiffer front springs add a big front sway bar and lower the rear as well.

I agree on the stiffer springs and big sway bar but the rear needs to be addressed also as Matt said.
Are you sure about that Chet? I've just assumed they were different on the FCs but never actually compared them. That would be nice to use stock components for everything but the leaf. No problem to punch holes in a leaf to work with the stock mounts.

I’m not sure where this going but I think it’s trying to improve handling. I’m no suspension expert, or for that matter any other kind, but I can tell you what my 64 GB has. I have both front and rear sway bars. I have a front spoiler which about 5” high. I have 17” wheels with Bridgestone 205-45ZR17 tires which end up close to stock outside diameter. It corners very flat, no sway, no pitch and roll.

Standard steering gearbox on FC’s are 5.5 turns but I believe the steering geometry on FC’s only allows 4.1 turns. I just installed the EPAS (electric power steering) on it and steering in parking lots just became fun. It’s adjustable too so I can dial in as much or as little assist as I need. Sometimes we have 9 people in the GB and steering was a strain with the extra weight.

I would think before trying to modify the suspension with adding a rear leaf spring, it might be better to inspect all your current bushings, shocks, ball joints and steering linkage first, repair as needed. But maybe you’re trying to use it in a more aggressive manner, not sure.
