Hey all you VW-nuts! 
I'm about to buy some Porsche wheels, 7,5"x17" up front and 9"x17" rear.
My car is a 1303s (super beetle) with original front beam and original (lowered) springs. I have widened fenders, about 1,6inches up front and 3,2inches back rear.
My quiz is: What kind of offset (ET) do I choose to fill my fenders all the way out, that included adaptors/spacers from standard VW-pattern to Porsche-pattern? As for tires I was thinking 205 and 245/255.
