Moin, ride a c20xe in an ASCONA C, but not on the road, but on stubble field races.Last year he was pushed together in a draw, and had to build a new rear.Now he has also become heavier and also not so lively.So the Golf 16v is faster. Engine is so far original, have only n red Riding Hood on it, lighter flywheel. Does a many times n have some advice? What about sharp camshafts ? valve springs ? Cossi head ? And where or who would have what? Thanks first of all greeting Temple13
