Rack and pinion steering.

This thread is for my drag car.
On a 8.50 roll cage, they don't do any of that x-ray or destructive testing. they check thickness of the steel tubing.
That's legal to 150 mph.
What I'm saying with this example above is when a welder knows what they're doing they trust their welds.
Also drag race track pits have a lot of space to make wide turns.
I put about a ton of force on the tierod end, and nothing moved or bent. Good enough for me. But being sure a welded steering Arm is good is about as important as it gets . A better way came about on another build i did. I used two by half inch bar stock to add the steering arm, using longer bolts. That worked well for a street car i built with rack and pinion plus coilovers.
