Welcome.
Love this car. No other Vw handles like the baby you've just picked up.
ABF is a tall block and has been known to cause clearance issues. I'm running a 3A with a piper cam in my GTX just now with no issues and the acceleration is fantastic.
Have gone down the Vauxhall route with the brakes as well although I found the stock brakes were fine if you kept up with the fluid changes.
I don't think the rears need discs as the majority of braking is done up front...my opinion anyway.
Welcome to the love affair!
