stitch welding the chassis...FC

im in the process of removing all the "tar" to stitch weld the chassis of my FC. this wil be a full drag car when complete. im looking for tips/info on doing this. i am a certified welder, so no problem there.

what points need to be taken care of? do i tack weld every inch or so, or weld every seem in tight in the whole car?

also, the hood gaps on my car are off making think the front end isnt exactly true. should i take it to a body shop and make sure the car it strait first. or can it be straitened later on after the stitch welding and cage have been wleding in?

thanks ahead of time.

Have the car looked at before you start welding on it.

You will want to weld the seams 3/4" to 1" long with a few inches between them. There isn't an absolute number.

It is worth mentioning, as a certified welder I am sure you know to move around the car while welding in order to not build up heat and warp the chassis.

yep, just tack it every inch, then keep filling in the gaps as it cools down

On my RX7 we removed all the tar and filler in the seams and welded every seam we could find. The car is a 1985 GSL-SE mini-tubbed and when we were done the car was very rigid. Not a lot of flex and leaves much harder off the line now. I would recommend this process to anyone that is serious about drag racing.
