Straight Axle - This suspension "technology" was so good it was instantly BANNED

[chopter33]

id like to hear an explanation why the rumley device was allowed and the straight axle was banned immediately.

they were both banned over the "off season" of the year following. i never wouldve imagine it wouldve taken that much work to stick a straight axle under a dlm. i really like the cantilever parts

Yes and no. Lucas banned it before it showed up. Woo didn't until the off-season.

Great video. Really interesting stuff about figuring out the steering. I love this kind of info.

I watched and thought it was a great story. I don't think it was so much about the straight axle as it was the suspension and ability to eliminate bump and roll steer that scared the big fish

If anyone from 80’s era of the Ark area remembers, this goes back to 81’/82’ ---- Crawford County Speedway, Van buren Ark., drivers last name was Felker (uncle of Denny Felker), he drove a wicked home built DLM that had a straight front axle, and was center steer.

AK is my favorite DLM driver. I love the innovation and his love for the sport. His cars not being store bought impress me. It’s no surprise that powers to be banned his straight axle car. We as fans should all send AK some money and help him fund his program. Imagine what he could do with a bigger budget.

Its comical to me that they didnt know why it really worked so good, but it was banned so quickly LOL.

. You got it right. Exactly

Rumley device was same story. Just as Austin said if he understood, he could have reproduced the results, Rumley #6 in 2016 was a failure. If Kevin had a firm grasp of what he had, the #6 would have continued to roll.

@Lurker - Probably Corky Felker.

just got around to watching , I really enjoyed it , made me think of me and my pop,s about 25 years ago , we were always trying something , a lot didnt work , but some did and it was sweet when it did .....

Its been years so you might be correct. I remember one brother was Duane Felker but I don’t remember who was who in the Felker racing family. One of the son’s is still active in Midgets.

Any theories as to why this was better? Maybe that it allowed both front tires to be used over full distance of corner? Whole lot less waiting for the car to turn/push off corner. Not talking about reasons for it being outlawed. WHY did it work better?

It could potentially alter the load transfer and the tire alignment with the ground and with each other during the suspension operation. He could have improved all of these things. The trick is to determine which one provided most of the gain. If you know that, you redesign the independent suspension to maximize that gain.

The front layout of these cars is pretty unchanged since the first tube chassis. The way we race them now, it's honestly a terrible setup. Just like it took Rumley to expose the horrible flaws of the 4 link, the next gains will come up front.
