Im thinking about this and just reading one the threads got me having second thoughts about the 205 40 17s im thinking about getting although I know the alignment is a must for the 17''s What kind of offset do i need and should i just stay away from the 17's and go with the 16's ?

205/40/17 = Nooo rubbing, they have essentially the same diameter as the stock wheels (at least the ones that came with mine)... and if you go with a 215; well lets do some math.
205/40/16: .40 x 205mm = 82mm tire sidewall
205/40/17: .40 x 205mm = 82mm tire sidewall
215/40/17: .40 x 215mm = 86mm tire sidewall
16" x (25.4mm/1") = 406.4mm rim diameter
(406.4mm)/2 = 203.2mm rim radius
17" x (25.4mm/1") = 431.8mm rim diameter
(431.8mm)/2 = 215.9mm rim radius
Wheel radius + Sidewall = Approximate radius of wheel and tire
205/40/16: 203.2mm + 82mm tire sidewall = 285.2mm total radius
205/40/17: 215.9mm + 82mm tire sidewall = 297.9mm total radius
215/40/17: 215.9mm + 86mm tire sidewall = 301.9mm total radius
Check the specs on the height from the center of the wheel to the height of where the tire would rub, and check to see if its more than those numbers I guess.
As far as the width of the tire rubbing... I dont think that there are any problems with the 205's on the first gen. I'll ask around to see, but try and find out, cause I'd like to know too.
I had a question on offsets a while back on wheels when I first bought mine... Here is the thread my friend... I would go with +40 like everyone is saying. Here are some other threads too I found when I searched... Searching is awesome

Im sure there is more info out there... Oh yeah... forgive me for being a nerd and playing with numbers... It was fun though...
