I have thought about having one machined, but I don't really see any benefit in doing that other then looks?
As far as designing a push rod setup, I have a few ideas on placement and how i'm going to design it (no real measurements yet). But I think I would need to build the upper control arms first? and yes a double wishbone ( same thing as a double A Arm setup) system with a pushrod to coilover set up.
At the moment i'm looking at 13.84'' (Extended Length) and 10'' (Collapsed Length W/out Bumper) coilovers with 3.86 stroke
And the 12.84'' (Extended Length) and 9.50'' (Collapsed Length W/out Bumper) coilovers with 3.36 stroke.
As for the bell crank arms, I have not calculated the motion ratio vs. Suspension travel ratio yet as I cannot find the stock boxster Suspension travel ratio. That said I don't believe the upper control arms will have any effect on the pushrod set up other than placement, but I already have two ideas on that.
Also what do you mean by (There are completely different forces working.)?
That said I plan on ordering tubing soon. I have two sized in mind. The cost is almost the same. I'm just trying to get an idea on sizes. I feel that 1-1/4 is over kill and may be to big, However I don't know if .95 wall will be adequate.
What I am thinking about using for the upper control arms, any thoughts?
