I've had a good look around the forum but can't seem to find a definitive answer to my question, namely........what is the best size master cylinder to get for a hydro handbrake for my E30 325?
The reason I want to get one is cos within 2 drift days at Norfolk I've managed to rip the shoes off of the retaining backplate, so they clearly aren't up to the job.
Any advice would be much appreciated.
