We will be trying many different combinations in the coming season. Unfortunately, they will all be at different times of the season, so ambient as well as track temperatures will be vastly different throughout the year.

In my Miata track experience, I've found a 225 on a 15x9 to be the fastest setup on a course that relies heavily on handling vs. power. On power courses, a 205 is faster than a 225 on a Miata.

My stock miata on 225 RS3s and 15x9 and coilovers (all else stock with full interior, A/C, etc.) ran a half second slower than the Spec Miata record at Gingerman.

Some drivers rely more heavily on a tires grip than others do. For instance in the s2000s, myself and my friend both agree that my driving style tends to take advantage of tire grip more than his does. We're both fast and he won two national titles this year with NASA. But our driving styles are vastly different with mine relying more on the grip of the tires - which is also more dangerous at the limit.
