The big difference that I can see that is somewhat concerning, it looks like on my car the tabs are radiused to match the radius of the tube they are welded to, where on the speed car it appears that they are trying to weld a square boxed tab directly to the tube.

*disclaimer I am not a fabricator, just sell cool stuff for a living :)
I saw the same thing, flat "U" bracket welded to round frame. Radiused on the XX not flat. I haven't a clue what LOF is seeing with his "Wrapped around the bar" on the Speed Car. Since I have an XX I was curious what that similar joint looked like -- thanks !!

That bracket on the Speed car is not a flat bracket welded to a round bar. It is a forging with a radius matched to the bar and welded all around the bracket to the chassis tube.

He only see’s what he wants to see 😂

That bracket is clearly not “forged” either…

Question remains how they welded around the perimeter of a flat bracket to a round tube 😂

Because the bracket base is not flat 😉

Thank’s for pointing out that you have no welding experience at all, but you still insist on being the expert…

Bracket is flat, gap between the bracket and tube is filled with weld. Pretty easy to see in the pic.

Perfect. Thanks for the lesson.

This are tight gaps! Not a bolt to be seen in there 🤣

You’re making shit up. That’s not a forging. Stamping likely but to you they’re the same thing

Like I said above I wasn’t sure if they were all forged pieces or not. 😂.

Making shit up? This must be what it feels like being you!

Here's my only thoughts on this car...
With all the great fabricators/ chassis builders out there, they shouldn't be reinventing the wheel on suspension pivot points. Especially when you can buy them online at tabzone or kartek.

The front end lower arm mounts I'm torn..... while I like how they incorporated it into the front diff I also think it's going to be expensive when it fails. Instead of reworking some tubing and mounts, you'll be buying a front diff 🤷🏻‍♂️.

Overall, it's still a sxs

Rumor has it LOF is working on some forged parts to fix any broken bulkhead mounts.

I believe he is referencing the distance between pivots on a single arm, not the overall track width. That's how I took it at least. Being narrow at those points is focusing the leverage from any lateral stress in a smaller area. The Speed setup is more of a traditional design, and the broader mounts send the stress towards more of the center. Given length of radius arm and weight of vehicle being equal, the Speed geometry should make it stronger.

That said, materials used and manufacturing techniques can also lose what was gained...
Yea this is what I meant. Monkey is much better with the words than I am lol.

Can am for reference. Only fair all the utv's are shown
Pretty thin metal for sure. But not a known weak spot on these View attachment 1155714 View attachment 1155715

It actually is a known failure point, very common to gusset this on cars that are driven hard (actually, the entire X3 frame needs gusseting if you are going to drive it hard). The question that we don't know the answer to is, which vehicle has the higher ceiling in stock form? Anything can be broken if you drive it hard enough, but if you reach that limit sooner on one vehicle than another, I'd rather have the stronger one.

I think that's the general goal, make it as strong as can be given the available parameters. Cost, availability and time are the major ones that come to mind in this scenario.

Many years ago I was on a low buck Class 7 team. Part of our "prep" was replacing every bolt holding the sub assemblies on or together. It wasn't that we ran into damaged hardware at all. Putting the iron on those parts meant we put eyes on those mounting points. Looking for cracks or evidence of potential weakening.

Our worst race day failure was shearing a spindle. After that, we made a tapered jig to check them out. By we, I mean a friend of a friends dad tooled one on a lathe...we weren't that skilled. We couldn't afford the spindles which are now commonplace on sand cars. In those days, I think 2" hallow spindles were whittled out of unobtainium, heat treated with dragon's fire and quenched with unicorn tears.

I didn't go to the Sand Show, I didn't look at RG's preproduction cars from last year, or watch a video of him breaking a car. I didn't argue with LOF. 😁
I just took my actual car, not a number 😉, for ride down to the lake. Happy Sunday.👍

There is a reason they make aftermarket chassis for Can Ams….they are good cars when they are in one piece but damn you just chase broken metal constantly with them as they age.

You have to understand LOF is talking out his ass because his head is to far up RGs ass !!
It’s too 🤣.

Come back when your can insult me without insulting me.

It must be a bit deflating to point out someone's incorrect word usage and incorrectly use a word in your rebuttal.

I figured I’d throw him a bone and give him a chance. But I can always rely on you to sift through my refuse to find something to latch onto.

At least you admit your posts are largely refuse.

Also, you incorrectly used onto.
The correct verbage would be on to in this case.

Why be a hater?
I'm just trying to inform the ignorant much as you claim.

That was just a logical conclusion I drew based on the deductive reasoning you laid out.

Hating? I’m not hating on anyone. I wish you the best.

Pic of the upside down show chassis. I know nothing about fabrication so I’ll let the experts decide if this is better or worse than the one that broke.

Take another look. It appears that bracket on the Speed car is radiuses to fit against the tube.
idk but I’ll be 100% honest if that’s what held the trailing arms on my car, they’d have been cut off and redone day one. My car is 3000# tho but yea those are a weak link at best!

Well most SXS have less than that holding the trailing arms on. So there is that :)
