Does any one know the weights of the MWC bars vs. the Wolfe bars?

Wolfe 4130 - 60-65lbs
Wolfe MS - 80-85lbs

Just shipped a CM 6pt to Alabama... total shipping weight was 45 pounds. The same thing in MS will be about 62 pounds.

1.75 x.083 is 1.478 lb/foot
1.75 x .120 is 2.089 lb/foot

chromoly and 1020 DOM mild steel(we don't use the cheap ERW the other guys do) are the exact same weight by volume.

our bar and cage kits are guaranteed to pass NHRA cert upon correct install procedures.

That's exactly what I needed to know, thanks for making this decision an easy one.

What kind of options for door bars do you guys offer?

I dont think my Wolfe 6pt was that heavy. Maybe 60-65lbs but I never weighed it.

Those were just the weights listed on their website. Weather they are accurate compared to the actual amount of weight added to the car I don't know.

I guess it could be but doesnt feel that heavy to me.

Cool I'll look that up thanks studderin

Edit: that thread is a great resource shows the weight difference of the seats I'm looking at as well.

We can do just about anything, but the normal 1 piece door bar has 3 bends... at shoulder area, around armrest, at floor. Swingout sidebars are optional.

wolfe is 1.75 x .134 wall ERW, and every bit of 80 lbs, mine was 82 I believe, this was in 2004 though...

Eric how much additional is a swing out on both sides?

Paying the extra $200 or whatever for chromoly is the best money you'll spend. After you put in that mild steel cage, try getting 30lbs out of your car for the same kind of money, lol.

I know the chromoly is worth it for a cage because of all the material involve. But are the weight differences worth it on things like torque arms and a-arms? From my understanding the savings are proportionate to how much metal is being used.

For a big piece that uses a lot of tubes, yes, there is a decent difference in weight. For torque arms, k-members, and panhard bars, go with chromoly. For a-arms, especially uppers, the $150 price difference isn't worth the 1-2lbs you'll save.

What safer CM or MS??????? Doesnt CM shatter around the welds easier? Is a tenth or 2 worth it cost and safety wise???

I thought it was stronger hence why you can use a thinner tube and still pass tech, is that not where the weight savings comes from?

If you were to order a 6 point bolt in, does the rear 4 point part of it come assembled. It would be sweet if you had the swing out option and basically had to just connect the dots. I dont have the right stuff for welding CM but want it for the weight savings as I bought all my rear suspension in CM. After seeing how light my TA and PHB were compared to another steel TA I was very impressed.

If that were the case I don't think NHRA/SFI would make the Advanced ET(7.49) rules to use anything but 4130N chromoly round tube and TIG welded.

If the welding process is done right there is no reason for it to shatter.

My chromoly will be here in a couple days. Anyone have exact dimensions or lengths before bending? I'm doing a 6 point in my f-body. Joelster?? Anyone? I will probably measure studderins first but just wondering......

How good is the 6 pt for in the quarter?

9.99 ET

135+ you need a window net (not often checked), so that = halo to attach it (no more 6point)

Can you mig weld chromoly?

something about heating the surrounding metal and then letting it air cool?

You can weld chromoly with a mig, but it will not pass tech. NHRA does not allow it... however in other industries, it is acceptable.

Well I def trust your opinion, since this is what you do for a living. I had just heard that multiple times in the past and just recently from a metallurgist. Which is why I brought it up. He also said the bars in a MS cage would bend more than a CM cage before snapping.

Ms will bend more, that's one reason that it's used in nascar

Might want to check this thread out.

Eric, do you guys do the jig notching like Wolfe does if you pay extra? Seems like it makes the install much easier.
