Frame tie-in

Dave Goob Cook · 11-21-2007, 01:55 PM

To keep the car legal, and to ever restore it to stock, use a good bolt in kit, supplemented with a couple of welds here and there.
NHRA Stock Eliminator requires all the parts to be "bolt on", so you can see what is coming there.

I can't see the point of using Moly to weld to mild steel, but that is just me.

2007 rulebook states: Section 5A Stock Cars.
Subframes on unibody cars may be joined. Maximum-size material to be used is 2" X 3" X 1/8". Round tubing may be used to tie front and rear subframes together and join subframe in straight line extending through the car floor, with floor welded to member.

No where does it state that it has to be removable.

I stand corrected.

Traction devices are supposed to be bolt in only. Weld in the connectors though.

I have found that the bolt in connectors work better to weld in than the weld in type. I think the bolt in are made to fit a litle bit better so there aren't big gaps to have to fill. I would also recomend installing solid body mounts at the same time.
