last weekend, my fs onroad kept popping the A arm rose joint lower/outer on the front wheel hub on one side, and the A arm rose joint fwd/inner on the chassis- this one eventually cracked the plastic before the day was out...
ok, the fs plastic is far more brittle than the mcd- that's a given...
so i thought, why not make lower A arms out of aluminium, but with a difference...
why not HINGE it, ie replace the chassis rose joints with a pivot pin, the same as the upper control arm (wishbone)...
i envisage something like 15mm plate, cut triangular shape similar to the original A arm, hole saw the centre, drill a hole thru for to throgh bolt the outer rose joint, and drill a hole on the chassis end for the pivit bolt, knock up a couple of brackets to support either end of the pivot pin and bingo- a virtually indestructable A arm ;D
having far more range in swing movement, you could potentially jack the suspension as high as you'd ever desire
sounds good in theory...
