A really bad idea...

I don't even eat Wheaties, and I agree with everything Lurker Mick said. This question was just asked a couple weeks ago, the conclusion was it's a bad idea, the car will be more than uncomfortable, it will be dangerous, that may not matter to you, but it does to those who share the road with you. A car with no suspension will be all over the road unless that road is perfectly flat and straight.

 

I think he takes you for a ratrodder, which is understandable. You come off as both clueless and arrogant. There are plenty of cars built with solid rear ends; they're called purpose built drag racers.

 

If you mounted the rear solid and then ran it without tires, you'd be the Rat-Rod KING!!!

Hot Rodding is about overcoming obsticles, not making stupid compramises.

 

In Sweden during WWII all wehicles were confiscated by the goverment.
The only way to keep it was to modify it to a tractor.
Cut the body off, and weld the rear axle solid to the frame.
Ok! It works , but you will get a VERY bumpy ride.
Belive me i´ve driven this kind of vehicle, i´s a killer.

 

With a solid mount, the spring rate goes to infinity.

That is a recipe for snapping axles, bending frames, and breaking wheels.

The hard tail Harleys at least had the small amount of spring+stretch of the spokes to dampen it a little, but they were still very harsh. I cracked the frame on my hardtail Harley dirt track bike several times. Each time I fixed it, it found a new place to fail farther away. I don't want another one.

Dragsters run on the smooth with no potholes, washboards, or RR tracks, and have huge ballons to give a little bounce to it. Their frames are made to bounce and give, then are retired after enough runs.

Car tires with no suspension will have to find another weak spot to use as an outlet. What would you like to break first?

Think of your head hitting the dash in a 30 mph accident.
Steel dash= 30 to zero in much less than 1/32 of an inch.
Padded dash = 30 to zero in about 3/4 inch.
I choose the one that gives.

Even a really really stiff spring is many many times better than something rigid.

 

great line!

 

I have a cut off pickup that I use for a snowplow. The rear end is attached solidly to the frame. It will lift a wheel now and then if you go over rough ground. It works but it never goes more than 10 or 15 miles per hour, and not on the road.
Another truck I have had 14 leaf springs on each side of the rear end when I bought it. It had some give, but not much and was okay on good roads. I hit the mother of all pot holes at 65, and broke the frame. Now I have 5 leafs on each side, and replaced the back half of the frame.
So if you don't want to bust something I wouldn't do it. Not to mention all of the added bounce that the front end gets because the back end has no give. Watch a tractor trying to go 25 or 30 down the road and you can see how they bounce.

 

One more vote. Bad idea.

We had a 86' Dodge 3/4 ton pickup at work that the rear was so stiff you really had to watch driving on secondary roads. That thing loved to get loose and washboard on gravel or asphalt. Not good.

It was replacing an identical one which was totaled after it started washboarding on asphalt and the guy lost control and laid it on it's top.

It should have been a tractor. It had the power.

 

Yeah, that's what I was thinking. I had already mounted the springs outboard of the frame and it lowered it about 4-5 inches. I still need another 10. So now I gotta cut out all the springs and mounts and try a transverse set up. To get it low enough imagine the center of the axle sitting in the cargo/bed area. The rear yoke needs to sit at about floor line (Ford 9-inch). If the axle was sitting directly on top of the frame rails it would be perfect. I just cut some of the body to get an idea how it'll work.

Guys that are freaking...relax, I haven't actually welded my axle to the frame, just asked. It's not the end of the world. It's a website thread with a dumb newbie question that apparently has come up before. Those that offered up usefull advice, thanks.

 

What you are wanting to do is not safe... and is lazy... You should have your car taken away from you..... When is everyone gonna realize that cars cobbled together from junk and primmer in an unsafe manor isn't cool.....I hope its soon...

 

my dad had a 1932 chevy coupe in the sixties that was a drag car before he bought it and the rearend was welded to the frame. He was taking off one time and dropped the drive shaft at the trans rocketing the rearend of the car into the air, and ripping the rearend out. After that he installed leaf springs.

brent

 

Uncertain T was underslung out back, with parallel leaf springs adding the bounce.
There was a picture of it on here just a few days ago...interesting setup!

Here it is!

 

Compressed spine and a really ugly look on your face while driving. Not a cool thing.

 

That car cannot be considered a "driver". It looks like it would work, but not enough to be comfortable.
