Thanks for the great technical info. I would like to ask how changing to 18x18.5(front and rear) square set up or 18x.8.5(front), 18x9.5(rear) staggered setup affects total ride dynamics of the 86. This on stock height and springs. This seems to be a popular setup in most 86. Thanks.

I think to keep the inherent balance of power and handling of the FRS/BRZ, the tire size change should be minimal, regardless of going with 16", 17" or 18" to keep the same diameter, and relatively small widths. 225's and 235 width should be plenty for a light FRS, to be fun and agile as universal car. Going beyond this only if there is a specific purpose in various field of REAL racing.
