What size wheel do you have on your car now? If they are 16 or 17" your gonna feel a huge loss of power when you put such a heavy wheel on the car.. Remember unsprung weight (wheels/tires/brakes, suspension) it's quite critical to have lightweight components on the car for best performance.
If you notice stock we have aluminum control arms etc.. Porsche did this to decrease unsprung weight at all costs, then you ruin it with 19's from Antera. It will be along the lines of a 10-20whp loss because of all the added rotating weight. Not a good idea.
Going from a 17" 29lbs wheel to a 15" 11.5lbs racing wheel on my GTI took about 3/10ths off the car int he 1/4 from 13.5 to 13.2. Thats a lot considering the car was already going mid 13's then to low 13's just from weight on the wheels. You could expect a full half to .75 seconds slower in the quarter and say 1 second slower 0-60.
Just a guesstimate of course, but it's not gonna be pretty either way.
