Regarding the big-brakes topic, I've posted some new pics of the red Brembo 4-pot+M3 disc conversion I did on the 1,8Turbo.
Right now, I'm doing another mod, same red Brembo 4-pots+ 310x32 Wilwood rotors+aluminum bells+brackets. This last one is a bolt-on job for 'roomy' 15" wheels. The same bells and brackets with a spacer can be used with the 323x32mm Wilwood rotors inside 16" wheels. I will post pics of this one when all components are done.
I think both these solutions are more than enough for any gtv or 75 car, whatever the use.
