Update 17th May 2004: Mark 2 bump steer spindles now available. These require the tapered hole in the steering ball joint drilled out to 14mm ID with a very sharp bit, but need no fitted shims.

Adjustments to the control arm pivot points on the Ovlov.net racecar allowed us to run up to 5 degrees of negative camber, but introduced serious bump-steer. This has now been fixed with a kit which allows re-setting of the steering tie-rod ends relative to the control arm to "dial out" the bump steer.
High tensile machined spindles, spacers and rose-jointed "Heim" rod-ends replace the standard rod-end ball-joint, allowing adjustment of the height of the tie-rod to eliminate bump-steer and it's adverse effect on corner speed on anything but a billiard table smooth track surface. The prototype spindles were quite long. Production kit spindles are shorter, now we have determined the range of adjustment required. Note the alloy control arms, sourced from a 1987 model 740, and the change in control arm pivot point in the crossmember.
