stay with the proper size - 205 45 16. Otherwise, you car revs higher, it's quicker (acceleration), but slower (top speed). Plus your speedo is off... but that's only 3%, so at 100km/h, you'll be doing 97.

sounds like someone needs a camber fix too

I wouldnt put 205/40's on your rims unless you have really strong rims that can handle pot holes and rough roads...I had 17's with a 40 series profile and I will never go that low again...way to rough and bumpy, plus worry of damaging your rims is always on your mind...
