Things have changed since that car competed at an auto-x though. If you plan on doing National Tours and being competitive, the 275/15's are what you'd need.
The 255/13's are just too short unless you start playing with the final drive IMHO. I've been lucky enough to drive an ASP Z06 this year and there have been a few brief moments were we've been tickling the upper range of 2nd (72-75 mph). With the general acceptance that an upshift is about .1s added to your time, have a slightly taller 2nd gear (or more revs) and the 275 is what is needed to keep up the RX7's and their 9k redline (around 73 mph on a 4.7 rear gear). |

.. since if I find there's no reason to run a 275, then there's no need for a 15x9 wheel, I can save the cost and weight over the equivalent 15x8.

So are there in definitive answers out there, possibly in way of charts or possibly someone with experience with a wide array of these choices?
There seems to be a pretty considerable list of tires to choose from in the ultimate AutoX Street tire category. ie: Azenis, Direzza, S03, XS, RS2, RS3, etc. |

Except maybe that 225's are faster on 9's than they are on 8's. BTW, The new RS3 (when you can find them) are way faster than RS2's.
I appreciate your help the other day after I ordered too, Emilio, thanks! |

I've been gone all week in the "desert" of SoCal with no internet access, playing catchup on threads. Wheels and tires came in though, and the buyer of my Koseis was nice enough to have the wheels and tires combined so I just popped 'em on when I got home!
Pics to follow. |

^^^ I, envy. How much did it all come out to??
|
The wheels came out great on your car!
|
It was about $1200 total IIRC for everything, thanks for the compliments. :)

That's including shipping, applicable taxes, mounting and balancing, centering rings, etc.

And its completely worth it. You couldn't spend 1.2gs on anything else that would make as dramatic of a difference in your autox times. Pretty much any wheel/tire set is going to cost right around a thousand bucks...

$1200 is pretty reasonable for an entire set of brand new wheels and tires "out-the-door" IMHO.

Especially for a badass set. __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
