Tube chassis question

You're probably right, but I was thinking that if he is going to install a significantly more powerful engine, the chassi could use the help in supporting the weight. Also, I'm not sure if subaru engines are designed to take all the engine weight on the bellhousing mounts. If not then he could damage the engine case too, not just bend frame horns.

Alright I measured the 944 rear torsion I had lying around and it 59.75" from one side to the other where the wheels mount up at. And with some porsche wheels setting out another 2" easy per side thats about 5"4". Making each side of the Ghia needed to be flared a minimum 3" to be safe, that I am not going to flare out my car. So we can scratch of the idea of the 944 torsion.

What 944 trailing arms are you using? I've got '86 Turbo parts, and I was told that the 16x7 Boxster wheels are about the biggest I could go and not have to flare my Ghias wings. Seeing as how the 944 parts bolt to a type 1 torsion tube and uses 944 axles though, I can't expect either torsion tube to make a significant difference on the track of the car. I suppose the exception would be if the 944 transaxle is A LOT wider than a type 1 transaxle.

Yeah thats what the measurements above are from, its a lot wider. I will just cut the trailing arm mount on the vw torsion housing and move it up. That way when I lower my Ghia the wheels wont tuck in at the top, is caster or camber the word I am looking for?

Anyhow I have non turbo aluminum arms from 85.5

You're thinking of camber. Caster is how inclined the axis of rotation of the steering system is.
