A Arm funnycar suspension

My question deals with the front A arm suspension of a funnycar chassis. What is the size of tubing used in the fabrication of A arms front suspension in a funnycar chassis?

 

I'll check on our car. it might take me a day or so, the shop is 20 miles from me.

best route to your answer is SFI...

ask Rooman....he might have an idea since he builds TF cars

 

Or you could run aluminum A-arms.

 

Thanks for the response ,my chassis is 85% done but still needs the front suspension and rear 3rd menber to be fabercated .I was useing a straight axle but trying to the a-arm set up thanks

Actually SFI could care less about what holds the car off the ground. All that the SFI specs cover is the construction of the part of the chassis that surrounds the driver (and a few other sections in the case of Top Fuel).
Most floppers that I have had anything to do with use 1.125" or 1.25" for the upper leg and .875" for the lower (double) section.
