17" to ray's 18"
 

do i just switch and go cornering or is there some other adjustments. I want to put them on this week & leave for L.A. "Z"CON the next day.

I switched from the 17" OEM wheels that came on my 5AT touring to the Rays Engineering wheels that come OEM on the track model with no "adjustments". I do not have TPS or VDC.
Have since changed wheels & tires again. I think you can just swap them out, no problems. You will need the longer lug nuts that come w/the Rays wheels.
