OK kind community, we all agree that we need an affordable rear torsion bar that serves various needs. Factors are torsional rigidity, WEIGHT adjustability
We did this in a very simple way in karting and I see NO REASON it wont work in this application, first issue is material cost, WE can achieve the same result by design instead of spending are $$ on exotic materials
WEIGHT, again design over mass
adjustability thru design
here is the simple explanation of how it works, the current bars are turned to a shoulder for X distance, then you have the major diameter of the bar torsion is controlled by diameter and the length of the center section
A 1in diameter bar turned at a TAPER to the largest diameter, NOW we have a more rigid bar and have removed the weakest point and we are UNDER the 28MM diameter thus less weight and more rigid
In the center of the bar at his largest diameter of 1 in ( section between 16 and 20 wide ) its milled flat on 2 sides ( like a wrench flat ) now when the flats are parallel to the ground the bar is at its designed weakest point, when the flats are vertical its at its strongest point, Now If you have the need and smarts you can ROTATE the bar to the desired stiffness thus ADJUSTABLE
I have a stock ABARTH bar headed my way If you need exact science info I can measure its defection at a given weight and compare it to the 1" bar and get a degree of stiffness compared to each other
This style of torsion control has been used in karting for the last 10 years, its very noticeable when you rotate the rear bar which is what controls WHEN and HOW much weight gets transfered to the opposite side front
round vs hex, personaly I think that's just voodoo, you could make the argument that depending on how you locate the HEX bar you would have some measure of adjustability but it would be very slight if any at all because of it having 6 sides as apposed to 2...
I can produce a powder coated rear torsion bar in ANY DIAMETER HEX OR ROUND for $135, standard design ( like whats available now ) or machined as stated above
That is with knurled ends, American steel ( nothing from asia or the indies etc )
