I hate to say it but this definitely isn't a West Coast Drive (WCD).

That being said it looks incredibly solid for a first drivetrain. Adding a bellypan on the entire bottom would greatly strengthen things. Also how are you planning to tension the chains and what wheels are you using?

What do you mean? I thought west coast drive was just a dropped center wheel . if there are other requirements, what are they?

from the picture it looks like the center wheel is dropped but its hard to tell.

A west coast drive typically infers that the outer most point on your chassis are the wheels.

The ones that come to mind are:

Live axles
Typically 6wd dropped center (or 8wd in some cases)
Direct drive from transmission to center wheel
Dropped center wheel
Cantilevered wheels

Thanks I did not realize that.

Looks good! What is the total weight? And are your center wheels along a line perpendicular to the side plates, or are they slightly offset from each other?

Has anyone else noticed that the teams who developed the so-called "West Coast Drive" rarely ever refer to it as such? Strange how the name kind of took off.

Maybe cause they are used by teams on the west cost, so the east coast calls them west coast drives, thus, it just hasn't reached them yet.

Yup that sounds good to me. Im glad this one is not a WCD though per se. It seems that everyone has been jumping on the wcd bandwagon possibly without considering other styles of drive all the while neglecting to implement many of the key benefits of west coast drives.

I agree with you, but I am one of those people on the west coast bandwagon. It's a great system. It combines ease of maintenance, light weight, and depending on how you make it it can be fairly low intensity on the machining end. (of course other drives have their advantages too.)


Back to the drawing....That is a really nice sheetmetal drive. I'm guessing the middle is driven via hex and from their power is distributed to to the outer wheels which rest on dead axles. Are they custom wheels? The gearbox looks custom two, or is a standard andymark gearboxbox modified for mounting purposes?

Great design though, the whole sheetmetal thing is taking off...

I personally owe a thanks to team IFI for some inspiration with sheetmetal fabrication...I love seeing all the new with sheetmetal.

I believe that this is in fact not part of the sheet metal bandwagon... To me this looks like C-Channel is designed to be welded... Hopefully Stephanie will elaborate further on her drive system and it's components.

This is the most famous example of a "West Coast Drive".

Looks really nice! Any idea on weight or thickness of the metal. Also what kind of transmission/gear ratio is that?

I observe no flanges where the apparent bends would be which would make you correct and it not a sheetmetal frame, or it could be a lack of detail by the designer by simply extruding off of a preexisting plate rather than actually putting in a bend.

I'm interested about a couple of things.

1. Are those custom gearboxes? Or are they specific ones you found online?

2. What is the weight of the frame?

Other than that, this is not w WCD, or the definition of WCD that I am familiar with. But the frame looks nice. I'm worried that some of the extrusions in the frame leave the the metal between a little thin, but it looks excellent.
