Rear sway bar vs IRS

[datO)))]

So just did a bit more research. I'd like to upgrade my 411 in all areas.

One being suspension.

So I'm told that an IRS from a 240, 260 or 510 will work provided

I fab some mounting brackets. I'm also told that it will bolt up using

Existing factory mounting holes.

 

Now this may be a bigger improvement than I need for scooting

Around Portland .

So I did some digging and thought why not a rear sway bar?

Could I get some opinions on the matter. Pros/cons

It will be for my 1967 411 wagon.

Thanx

Why not fit IRS and a rear anti-sway bar?

There's no way any IRS will "bolt in" to a 411 ... and those cars are alot wider than a 411,so you would need big flares too

Stick with your leaf springs? Add a leaf to firm up the ride. Straighten the leaves or use blocks to lower... so much easier. Lowering IRS adds toe in and camber a total headache.

Why would you need either a bar or IRS for that?

Ok . I guess I'll focus on other Areas for now like brakes lol and tuning. And well everything. I don't know we're to begin with this thing somtimes. Thanx dudes.

As already mentioned, to get it lower start with 2 " blocks in the rear and either cut the stock front coils or track down some front springs from a roadster. If and when you do this invest in some new shocks as by now they have reached there usable life. I thought I have heard that the rear springs from a early z car might be a good substitute as well but that's on your time to research.

The. 411 drives very nice when the suspension is dialed.

If you don't already have front discs, Mike Klotz made a kit to convert I think.

Be sure to use DOT 3 or 5 brake fluid in these cars.

DOT 5 is silicone based and should not be used. 3, 4, or 5.1 should be used.

I lowers with blocks . I feel like the rear suspension could still be a smoother ride. I'm a newB so I'm not sure what a good direction would be to go . I put in new bushings and new/used/modded air shocks but the air lines are cheese Dick airlines and leake.

I'll researc more in the leafsspring department. Thanx mang!

Agree!  DOT5 brake fluids violate what you learned [if you were listening] in High School Physics.  "Fluids are incompressible".  It is, thanks to the lenghty involved silicone molecule, a compressible fluid and will give a "mushy" pedal.  Perhaps OK for autocross [although I doubt that] but a No-No for ordinary road use!  Simple molecules are stable and do not compress while long chain molecules deform upon themselves and so the volume compresses i.e. decreases under pressure.  DOT4 fluids are compounded to be effective in disc brake systems and have a high boiling point, so why waste time with DOT3 fluids?
