torsion bars and rear adjustment
Hello
Would you tell me the inner and outer numbers of teeth from a rear torsion Bar please ? And what do the two excentrical nuts really do ? (rear arms) thanks Philippe |

Inner end has 40 splines and the outer end has 44 splines. Rotating the torsion bar moves it 9 degrees per spline, rotating the radius arm, to which the wheel is attatched, moves 8 degrees, 10 minutes per spline.

The eccentric nuts serve 3 purposes and 2 of them interfere with each other. The biggest one is the ride height adjustment. It's the big (24mm) bolt that you need a skinny wrench to adjust. You loosen the big (36mm) clamping bolt and turn the 24mm one to adjust the arm up and down to fine tune the ride height. The other two eccentric bolts adjust the camber and toe on the rear suspension. If you look at how they work you'll see which one is which. They interact in that when you put in more negative camber you induce some toe out which you have to correct with the toe adjusting bolt.
