None of it is legal in NSW without engineer's report on the specific components used including strength testing etc.
Sure you aren't changing the basic suspension design but the components are all manufactured differently. Spherical rod ends like those on the castor rods cannot be engineered at all and are completely illegal for road use.
all depends on who engineers your car
so really, just engineer and register your car with standard parts, then switch to the goodies.
That's fine until you kill someone on the road and they go over your car.
ok..so lets clear this up for me, all other people intending to use suspension components with rose bush (spherical bearing)..and of course forum jockey.
there are a few people on here now using the t3 castor arms, so lets clarify that they are legal to use on NSW roads.
these types of bushes
ARE legal, allowed, permitted on NSW roads as long as they are covered and sealed by a rubber boot. Obviously to stop dirt etc getting into joint. If they are not covered by a sealed rubber boot kit, not allowed.
