John,
I've been thinking about your brakes, now that I have the necessary tap, for fitting Godspeed's, I would be able to fit yours as and when you get them, if you do.
It took me about 1 1/2 hrs to do mine, but I didn't have to split the caliper, but thats not too difficult.
Mail me at impreza_dood@yahoo.co.uk if you want me to do it.
Ron.
