At more than +5°30' of caster, we got constant rubbing of the inner barrel of the wheel to the control arm when maneuvering on the parking lane or pit box. Sounds bad and damages the inner side of the wheel, so the only option we had, was to limit the caster.Full lock is not interesting for us as you will never use this at a racetrack.
You moved the entire steering rack higher? Because this is the only option to correct bump steer (unless redesigning the knuckle) if you are planning to raise the mounting point of the upper control arm to the carbon tub (chassis).Our connection to steering rack is also modified to adjust bump steer so the plates are just a part of our whole solution.
Exactly. Most of the alignment shops don't even bother sorting out left / right differences, although perhaps not that vital, it can be done precisely and I strongly aim to do so. With more adjustability (track width, mounting points, more caster,...) even more problems arise and I doubt many of the shops would have the know how on how and what to adjust.You can use it for a street car but if you use too much of the possibilities of adjustment without knowing what you are doing you can easily do no good to your car.
