im getting ready to purchase 17's and tires to match but i have an ap1, what are if any adjustments i need to make to my car. all opinions are appreciated

 

get an alignment after you mount the new tires and wheels on to the car. Since you now have more expensive hardware make sure your alignment is good so u don't wear them out.

 

I would only suggest the alignment if your tires are worn unevenly. If they are you do want to have the alignment. If not I would skip it.
Like I answered in your other post just make sure you get wheels that are made for the S2K.
If I can help let me know.

 

thanks jim, i also was wondering if i needed to adjust the speedometer so the mph and odometer are correct

 

as long as the overall diameter of the wheel is the same nothing needs to be changed with the spedo or odometer.
