There’s been a lot of debate on the board and elsewhere about bushings from ‘snake oil’ to ‘totally transformed the car’; you can find some of it here and here.
I 3D printed my own and experimented a bit with fit and have been running with the pair I found best for the last couple of years. I found they did make a difference; the car felt tighter, especially on long curves.
Possibly, as suggested at the time the same could be achieved by just replacing with new OEM ones but I’m happy with what I’ve got.
