Nissan 370Z Forum - View Single Post - Why 18" vs 19" wheels/tire for track and Auto-X

Ok, so after doing a obligatory search I cant find any threads discussing performance of 18" vs 19" wheels on the 370z. However, I see a lot of folks talking about running 18" wheels on their track & auto-X cars.

I am assuming that on a track the loss of gearing is more than made up by benefits reaped by...

1.) less rotational mass
2.) bigger better cheaper tire & wheels options

Is that it?

But for auto-x I see guys running 18" too...which is stranger to me since 2nd gear top speed is such a critical factor for most Auto-X cars.

Anyone care to tell me why they choose 18" over 19" for Auto-X?
