Mats, I think it is not so difficult to make lower arm with torsionbars lighter.
The oem lower arm is an U shaped, some square or round tube with material at the right places can do the same with less weight. The biggets problem would be making the splines for the torsion bars. I'm not sure if the splines from oem part (cast iron?) can be seperated and welded into the new construction.

Really? I'll admit its 3 years since i've seen one in the flesh!Mats wrote:No, cast iron. Pretty useless...
bollox. Should be really easy to build a strong enough tubular arm then (Cast Iron = shithouse in tension).
I'm astounded. If someone like ford used forged steel components in '60s family cars, why the hell did Alfa cop out on this?
Oh well.
Thanks Andrew for supplying the originals. Had two machines running for a day just to cut four pairs. Not the lightest items around but thats not a problem for me as the torsion bars are history and will make up the lower arms shortly, so i will still be ahead in weight (saving).
I dont think any sets for resale use at this stage will be made as its a lot more costly than I thought. If there is enough interest and can get price down then we can make a plan. Barry and I are working on this aspect at the moment. If any one is interested contact Barry.

Just finished making pins. These pins are non adjustable unless I remove the taper in the stub then I can have a straight shaft and add spaces to the pins. I will try that if this set is not perfect for my set up.
This is probably the first case where some one has cut(destroyed) beautiful 305mm to 290mm so they can be used in a fifteen inch rim with the eight pot calipers. This 305mm will normally work in the 15nch rim if I was using smaller calipers. Sorry for cutting your discs Barry. (yeah i know I am going backwards but I have to use 15nch for race regs). Anti roll bar is in the making. Wish our currency was stronger so I can just order from RS.
Anyway here the pics

If someone goes to the trouble of fabbing lower A-arm I wonder if it would be worthwhile to put (taper)rollers bearings in place of the bushings. Those bushings are under some load at least on a torsion bar car. Perhaps the coil-over reduces the need. Has anyone worked out good dimensions for arms and uprights to optimize a lowered track car?
