 |

Toyo has a nice r888 available in 225/40 for a 14" wheel and I was thinking of dropping down to the smaller size.
I can think of a couple advantages including gearing change, lighter unsprung weight, lower center of gravity, they're even wider tread than the 225/40/15. Assuming a 14" wheel would fit over the brake calipers of course.
Only problem is that I can't seem to find any wheels that would work.
Ideas? I think this would put me into "go kart" territory for handling. |

If you have a 5 lug brakes you can't use 14" rims. The brakes are too big for them.

I use 7J teledials. With Toyo R888 205/50/15. I think you can't go much wider, because if your car is very low and negative camber (like all track cars) there is not much more room for wider tyers.

More like it'd put you in the Spec Miata category of handling...

Not sure if "Spec Miata" is better or worse than now... Car handles pretty well as-is, so I would think it would handle and accelerate better with the smaller wheels with wider rubber than the 225/50/15's on 15x6 cookies that are on it now. Less unsprung weight for sure, maybe by 5lbs/wheel depending on wheels. That's a lot.
Can anyone confirm there is nothing in 14x7 that will fit over the 5-bolt calipers? Minilite? Panasport? Old Fuchs? Miata wheels? I thought something would fit... |

I believe those are Spec Miata tires, is what I meant!
