stock camaro subframe

[paulk68]

when using a stock camaro subframe I have read alot of people say to weld it up to wake it stronger. I assume this means the seam running down the middle of the rails but what other areas are people welding? does anyone have pictures of a before and after?
thanks

You will have to look at your frame and see where the factory missed. Its pretty clear...well you can see through that is.

You need to keep the heat down & skip around or you will warp the subframe. I've heard some horror stories. The frame overlap area can hide oil & mess up weld quality.

Thank you for the great info

I have a spare subframe that needs a little adjusting due to left front wheel side impact. Spec's aren't too far off but it still needs to see the frame chiropractor.

My debate is: Which is correct? Straighten, blast and weld or blast, weld and straighten?

I would straighten first. Adding more welds will add stiffness that was not there during the impact. That will make it more difficult to return to factory specs and could cause some undesirable side effects after pulling.

That's a very nice frame schematic. I'm assuming that all the first gens are exactly the same right? I know they all interchange.

there are a few subtle differences. 67's are closed off inside of the bumper mounts, bump stop in on the frame too.

Measurements are still the same right?

Seig, Blast, Straighten & Weld! By Blasting 1st, you can see if there are Cracks. You might need to Break & Cut, then Straighten, then Weld it up. This is what I've done using a Celette Bench!

Does welding up the stock frame make it comparable to an aftermarket frame? I'm guessing not. Does anyone know how much of a difference this makes.

[rallystyle]

figured i would bump this up instead of starting a new one.

what is the preferred method for welding. i only have a tig and was thinking that should be fine? and er70s-2 filler ok?

[Vince@Meanstreets]

Personal preference.

welding it makes it dramatically more stable...with good control arms, steering box and arms and it is very good, you can run a 10 inch wide rim with the stock frame, on some aftermarket frames you can run 11-12 inch wide rims

[Vince@Meanstreets]

Once you get in you will see how inadequate the factory welds are. TIG should be fine but after it's been baked and media blasted. 70 is good
