As i'm half way in in this swap things that i post is mods that i already have done :).
Another thing i did when i did the brakes was building new rear control arms, narrowed down track with with 16mm/5/8" to accommodate modified Rota wheels.
That included shorter half shafts, narrowed in my lathe, they were hard so i have to buy some expensive inserts/tools.
I also made a jigg to get angles correct when welding.
They are now adjustable.
I'm going polyurethane bushings as i want this to be a fast road car and not a track car only.
With them i could go with the R180 for last summer to sort out the brakes.
With the now mounted R200 i have to make new ones again🤣.
