Steering & Suspension Geometry Questions
Sometimes a little bit of knowledge is dangerous and I hope Iíve not entered that zone. Still sorting out a few suspension/steering details and not wanting to create more problems with a mix and match suspension/steering. Iíve listed my current alignment specs below.
1. My steering is 12:1 constant ratio power (Lee Built) with short outer steering arms and a long (5.78Ē) pitman arm. Result is a too quick ~1.75 stop to stop steering. I plan to switch to a shorter (5.25Ē) pitman arm to slow it down.
a.) Any idea how much this change will slow the steering down to a more reasonable lock to lock number of turns of the wheel? ( One of Mr. Pozziís articles suggests about 2.5 turns L to L with a 12.7 constant ratio box with short pitman arm and short steering arms. Just curious if anyone has tried this combination and can report L to L number of turns.
b. ) Will I need another alignment or other adjustments after I change to the shorter pitman arm?
2. I have C5 front spindles that are quite a bit taller than stock, but Iím still using standard length upper ball joints and control arms are stock. David Pozzi has suggested using tall outer tie rod ends to reduce bump steer. Any issues with just swapping out the outer tie rod ends or will this also require another alignment?
Current alignment specs are camber: -0.3, caster deg: 3.7 deg, toe: 0.06 deg., total toe: 0.11 deg
