A arm material

[bzrse7en]

Hi Justin
I have design approval on a Lotus 23C. LVVTA has specified A arm material as a minimum of 22x2.5 wall.
As far as I can tell, this size doesn't exists.

I can either use 22 x 3 ERW, or schedule 30 21.3 x 2.41mm line pipe.

I used the schedule 30 line pipe on the last car I had certified and it was approved for that, although it falls outside your minimum specs.

I would prefer to use the schedule 30 again if possible, is this OK?

Thanks Patrick

Hi Patrick

The minimum specs for custom a-arms are all contained within the NZ Hobby Car Technical Manual.
If the TAC have allowed a variation to this, then 22x3mm would be the best option.

Thanks, Justin

Just as I thought you'd say .
No problems, thanks for your time and efforts Justin, have a good Christmas.
