Just a quick note to say that a suspension company here in Brisbane are currently manufacturing front lower control arm castor bushes for the mazda 3. It is still in the R+D phase at the moment (My car is in getting them fitted this week).
The are made as a full replacement for the OE bushes and are designed for more castor and anti-lift. They will be made from 70 duro (Don't quote me on that)
Pricing will be around $180 for the pair and $60 for the smaller ones in the front of the arm. (Not exact prices as yet either) This is an un-fitted price. Hopefully i can sort out a MPS Club deal with them.
The will be available very soon for those of you wanting some more cornering ability.
I will post pics when I get them and specs and prices of everything available.
