Looking for some advice on what gauge mild steel tubing to use for reinforcment of my 914-racecar project.
The rear truck will get an X brace or like, and a bar side to side.

The frt truck where the gas tank was removed will get a brace between the shock tower.

The rear trailing arm ear will get a bar from the trans support to the mount.

And the upper rear shock mount to the firewall will get tied in but not to the cage.
So I was thinking of using a mix of 1.5 1.25 and some .75 16ga steel.

Is that thick enough? See pixs for reference.

P.S. I was wondering if anyone here has tried Tubular control arm reinforcing??? Not as overkill as boxing them. IMHO

Are you keeping that front bulkhead? if so you may not need the front crossbar.

Racer Chris was king enough to post up some pipe dimensions (gauge) on another thread.

I'm sure you know this already
but becareful to read the rules first for where you want to race
most PCA and vintage races will not allow weld in bars like those
or if they do allow such, it will bump you into highly modified classes

I once ran against martin snow in his twin turbo 4 wheel drive 911 with 600 hp (me in a 2.0/4 stockish) because of such rule books.

needless to say I only had to drive 9 laps of a 12 lap race. He won and drove all 12!

So Where would I find that tread on pipe size???

Neff you are so right on what you are saying thats why I am going back to running a four when for 7 years I ran a 3.2 in a 914.
I am running POC V5 so I will be OK and I will do some TCRA racing.
