Rear control arm bushes - 2 types? Passive steer?
 

Hi all, doing a rear subframe restore, bushes, powdercoat, torsen diff going in etc etc

Will be fitting either ILM rubber bushes or OEM bushes.

Misleading info coming from various parts lists.

Car is a 93 1.6 UK car.

Lower arm, outer bushes (to the upright). Should they be two types, or both the same? The OEM parts list on this forum disagrees with other suppliers lists and my own research.

Presume the two types (different hardness materials) is what goes towards this supposed passive rear steer effect.

And finally - does it really matter?

OEM parts catalog lists different part numbers for forward vs aft on the outboard rear lower bushings at the knuckle.

NA1-28-4B0 for the back one
NA1-28-4D0 for the forward one

All years NA or NB, thats all I know.
