U13 bluebird front coilovers will bolt straight in if the body's the same as the AUS delivered U12?
I got some off fleabay, came from Thaiwon. I think it was about $600 for the fronts with a 10 or 12kg spring rate (can't remember..) and "drift dampiner oil" - whatever that means.
Worked good though, height, dampener and camber adjustable.
For the rears I was going to TIG some Coilover sleeves on with some beefed up mounting plates to save suspension/heart break. You would need stainless or something sleeves, not AL like a lot of them are.
Had 8kg/mm rears which worked a treat, and they were on fucked stock shocks.
Legal?
Hahahahahahaahahhahahahahahha haha....... No.
Things to consider.
