Macpherson strut sucks, short arm long arm coilover suspension is the best.
The first two builds of this car resulted in the knowledge that factory sheet metal is entirely too flexible, in our way and in the wrong spot....1st gen W stuff remember.
The amount of unibody Flex, strut bending and suspension movement on the TR definitely make me think the tube chassis was the correct way to go.
I already have a couple ideas for the new subframe on the front and rear makes a few things with the suspension. Front I want to have cantilever upper arms and move the coil overs inboard
