2" dropped spindles
Posted by: tknobby ()

And now for something different.

I wanted to lower the front of my 64 Spyder but didn't want to cut the coil springs as this would make the front ride harder. I like the way the stock length springs ride. So I tried reworking a set of S-10 2" dropped spindles for this car. I got all the way to the point of fully installed but when I tried to turn the spindle to full lock I found the caliper hit the crossmember before hitting the lock stop. And since I had just had the crossmember powder coated I wasn't going to grind away the offending area. So I stopped.

After a little research I decided to just fab my own out of steel. These are the result.

They fit onto the stock ball joints. The upper control arm rises 2" to help increase the negative camber gain during suspension movement. The bearing is a hub unit from a Corvette. The stock steering arms bolt on just like on the stock spindle. They require an upgrade to disc brakes as the drum assembly will Not fit.

These pictures are of my 65 Monza but the Spyder has the same setup.

My next set will have steering arms built in. These will be the same length as the original GM quick steering arms.

Thanks Don! I'm beginning to fab these for sale.

Late models will Not be able to use the speedo cable so an electronic speedo will be required.

Is that a Front Wheel Drive hub you used there?

Tom, that's not technically a spindle as there is no shaft for wheel bearings. I think the GM term of art for that device is the "steering knuckle housing". This would be the American Flat Six dropped steering knuckle housing thread.

I believe it is a C5 Vette front.(Tom can confirm) For reference, the aftermarket VDO electronic speedometers can be driven by a Hall effect sensor, which could be hooked up to the early model drive at the transaxle, (or maybe under the dash?) or a magnetic pulse, which should be available on the ABS output wire from the above hub, or a small add-on GPS based sender that you would mount on the dash. You have lots of options.

No. Front wheel hub, no drive splines on this one.

Correct Seth. This hub does have a wheel speed sensor. I bought the harness that connects to this sensor off ebay for under 10 bucks. This sensor provides the signal for my Autometer speedo.

Autometer said they needed a Hall effect pulse, not a magnetic pulse. Have you tried that out?

My dash isn't quite finished so no, not yet. The Autometer instructions I have said their speedos work with numerous types of sensors so I'm going for it.

Nice work Tom and lots of great tips here for us all. I definitely like the idea of drop spindles versus cut springs and your disc conversion is really clean looking too.

Also to add to your other posts of your cylinder head work that’s some nice work too. I can only imagine how much time you have in a set of those welded chambers and all the big valve work but I know it’s a lot. I wish I had more time to do that kind of work but I just won’t until I can retire. For now I’m enjoying the 4 spider diff mods as they are much smaller projects time wise that I can fit into my schedule and actually get done in a reasonable amount of time.

Thanks again for sharing and I’m curious if you have made any strides for the rear disc set up yet or is that the next chapter?

Are there clearance problems with the wheel being 2" higher in the wheel well?

I'm running 15x7 Superlite wheels with a 5" backspace, 205-55 tires. No rubbing anywhere, no clearance issues.

You can do a procedure on the 65-73 Mustang to change the angle of the upper control arm and increase handling; it's call an Arning (or Shelby) Drop.
The Shelby Drop is only 1-inch because anything more creates ball joint binding which will cause the ball joint to break.
The binding is fixed by installing a wedge kit on the ball joint along with the increased drop.

Have you checked to see if by raising the upper control arm, you aren't putting the ball joint in a bind during suspension travel?

Full travel in both bounce and jounce has no ball joint binding.
