ok, i dont get this? why are you swapping out your front suspension?

keep the front struts stock, get a weld on coilover kit and new inserts, AGX or something and a set of camber plates.

thats that sorted.

if you want bigger brakes, you can do the BA falcon and R33 conversion, just re drill the rotors to 4 x114 and bolt it all up.
might need to go to pirtek to get a new line from the strut to the calliper, so check that.

not sure about LCA option

im sure someone else can suggest one. or i can sell you a DIY adjustable LCA kit that you can weld on.

You can use MX73 RCA's

then you just need to sort cator rods and steering knuckles.

maybe someone else can suggest some options for this?
