1x IRS Nissan Semi Trailing Arm Subframe for reference

Now were going to slot the holes a shitload to correct camber for lowered cars

The idea is for street driving you get it set to about 1deg neg, and for track days you can take the correction out IE when you drop your car and the rear camber skyrockets to like -2.5 you can add neg camber back in up to this amount.\

And the start of the adjuster plates, so far they are only 4mm thick but I am going to double skin them to give them some beef as they will need to hold a fair bit of tension. I will also gussest the sides

Here you get the idea that there will be a plate welded across the bottom ( 7mm flat ) with 2 holes drilled in it to match the adjuster bracket.
Its just the the chain adjustment on a motorbike.
Tomorow I need to file the bottom of extension pieces dead flat, and then I can tac weld the big plate that goes underneath that the adjuster bolts to.
I am doing all the work, however this will be tig welded by a guy who is friendly with the local Certifier
