Hey guys.

I'm having my sedan project beated and rust cut very shortly. And I'm considering seam welding,
As I may remove it from the road and use it for hill climbs and track days a few years down the track(no rally).
The question I have is what should I look having welded?

Everything stitched both sides of every overlap. Rails ect

Bugger sounds like an expensive way to go.

So there isn't just specific areas that need to be done without going overboard??

Firewall where it meets inner wheel arches and footwell stich up the chasis to inner wheel wells too rear same from what I look at. Try strengthen brace across rear seat area.
Anywhere to strengthen and reduce flex

Bung in a roll cage too ... That will help stiffen up the back

Not looking at putting a roll cage in until she's no longer on the road. As I'm having the rust n dings fixed, it is easier to have the seams done now, if I can afford it. That's why I'm asking, as the body work is already setting me back the better part of 3k.

dude all i can say is good luck. I've decided to go the other way cos i feel i wont use the car enough. track car --repairs, welding[which i can't do]drain tanks[fuel] when car is standing plus plus plus.buggered my doors by removing inner panels [weight]Lexan windows removed and put glass back. In general datsuns sit on the road so yeah it's going to be quite a job.I kept on changing before i even finished the car --still have not finished. throttle bodies [zx6 bike] and gotech mini x management etc made almost 100kw on base map with leak by exhaust and lsd which was not welded [blocks it rests in [alfa diff].Every time you strip you replace it --strip int replace with cage and fire ext --yeah so lots of respect for those building their own cars.

Stitch welding is a good way to start stiffening certain areas, the entire engine bay is a good place to start, then connect the front frame.rail.to the rear frame rail, then start at the rear suspention mounts and start stiching away from them, over all the best results you will get is connecting the fram rails, best return for your $

If they are already doing rust repairs and have the welder out it should only cost you another day to have it all welded up.
