Banana Connectors

I just installed my first prototype subframe connectors into a friend's car. These will be available for sale in the next month or two as soon as I work out a few more details. The ones I made today are welded, not bent. I plan to get dies for the bender for the rectangular tubing, but I also plan to have welded vs. bent tubing tested to see which one is stronger. With the proper reinforcement, I think welded may be stronger.

Here's a few pics of the install...

Finished product.


All alone.

Any comments positive or negative are welcome!

Nice Tom. I would add gussets to the seat angle.

Good idea. I was thinking about that also, but the load at that point is in twisting so it should be pretty strong as is. Doesn't MM use a channel instead of a piece of angle? That would give it support on two sides instead of one.

If I stick with the weld instead of bending, I'm going to add gussets to the rearward weld at the top of the connector. I could tie that in to the seat brace. hmmm.....

Hey, if anybody wants a set of connectors at my cost (about $15), bring me your car for half a day and I'll put a set on. This offer is good for ONE person only. First come first serve.

Damn, your phone should be ringing off the hook. I should give my stuff away on the "For Sale" forum.

That's was actually an accident. The guy I put them in for didn't care what color we painted them, and low and behold, I just happened to have some yellow paint lying around.

The final product will come in bare metal.

Looks good, Tom.

I think I would consider using a u-channel piece for the seat mount (simular to MM's), I think it would be stronger and no harder to make.

What size tubing and wall thickness are you using in compared to MM, Griggs, ect?

Sounds like it's unanimous for the channel seat brace. I'll look into that.

I'm using 1" x 2" x .120" tubing. It's the same thing MM and Griggs uses as far as I know. MM actually uses 1.25" x 2" x .083" for their full length. I guess the larger size offsets the thinner wall. I'm thinking about using the same thing, but I want to test each one to see what the difference is.

I'll try to figure out when I can run down there. I'll give you a shout this week.

Thanks man!

Your trademark should be that you paint every set that leaves the garage yellow!! They look good Tom.

Any chance you'll be making any Focus chassis stiffening pieces?

I thought about that, but I weld much better than I paint.

I'm not even sure if the Focus needs to be stiffened or not. If I ever get mine back out of the shop (horns died) then I may put it up on the lift and take a look.

Tom,

Looks great! Looks as if someone might be able to run a side exhaust with better clearance also.

I do have a question about the rear attachment points, based on the above yeller picture. The passenger side looks a bit skewed (camera angle?) Would tabs on each side be beneficial? {edit: oops, that's front driver's side, looking back at the pic....}

When you work up pricing, call me a player (not mine, my pops new 03). While I'd like to have em for side exit clearance, I'm just not up to removing the MM FL's.

Steve
