Check out the Nissan S13 rear suspension kit

You can tune your steering geometry towards positive Ackermann in just a few minutes even at trackside without messing up the alignment

If Ackermann is positive then toe is 0Camber: -4 +/-0

which allows to change suspension stiffness and handling very quickly without changing the spring and messing up ride heights

For lowered position it has also some adjustability in case someone has already lowered the rack and it doesn't match with our designed height
