Suspension Strength: Maverick R vs. Speed

[sand shark]

Not sure how those people managed to break the lower arm on the Maverick R. It is an odd place to break.

Here are some pictures I snapped of the arms at the Sand Show.

They look pretty stout in person.

your not serious are you. those arms look weak and are super thin. the Pro R has some beefier lowers but not the mav R

Thin as F### though.

It is made from sheet metal stampings, and your picture shows a crack in the weld.
just saying...

You have some eagle eyes. I don’t see any crack in the weld.

So have you seen them in person?

It’s pretty obvious, blow up the image and look closer. Also, you can look inside the holes in the arm and see how thin the steel is.

Look at the connection from arm to bushing.

I don’t see any crack in the weld where the Arms broke in the other pictures. Those were the arms on the cut away car.

Here is a picture of an arm off another Maverick R

On that one you can only see how thin the stampings are.

yes. lots at the SSSS

Did the ones that break, break at where those holes are drilled? Those holes might be the planned weak point.

The two I seen looked closer to the bushing, but I'm not certain.

The bend would be the weakest area.

The bend would be the weakest area.

I am just curious why 2 holes. One to vent welding gases/pressure I could see. 2 I am thinking it's for a reason, maybe accessories can bolt there. And having the holes on top would introduce water/moisture into the a-arm.

The ones that broke are more in the bend area.

Speed uses holes to e-code the interior of chassis and suspension components...?

I posted on here and RDC that I was talking to two guys from Can Am. One who was some sort of engineer, said that it’s basically and engineered fail point (like the X3 arms) so that the arm would break away and not rip the pivot points out of the chassis.

My smart ass comment back was so you break the arm, and take out the ball joints, shock, the rack. Lol. He’s comment back was those unbolt and are a lot easier to replace vs the whole chassis. I agreed and told him I was just being a smart ass.

The fix as you know Shark is going to be a weld on gusset plate to strengthen that area. In 3 years they will release a new 15% stronger arm.

Shark what do you think the cage tube thickness was? I was thicker than the OG X3 cage. I tried to get a feel of the thickness through those rear beauty bars, it seemed more than .065, but not .083. I don’t know the standards for dual phase materials, so maybe they have an Im between or maybe it’s metric?

That (idiot engineer, in my opinion) should consider that the failure would most likely happen at high speed or impact, and that these cars are not remote controlled drones but have onboard operators; so, the lives of operators in the car should be the first concern.

I’m not going to question the intelligence of the engineer, he seemed smart to me, and I have no idea what he’s an engineer for? Might be for the plastics or for electrical. Who knows? He never claimed to be the person in charge of the Mav R suspension. The first guy was a parts distribution manager. He’s the one who suspected a rock or something hit the arm. He waved the other guy over who said, like the X3 the arm was designed to have a “fuse” to protect the chassis, and that the breaking point was extremely high, which I assume it would be. Both arms that have broke were not at super high speeds. Atleast the yellow arm was not from what the Rep and the guys at Veys Motorsports who was driving it. They were not even sure what they could have hit to make it break?
