handling with 315's?
 

how well does the car perform with 315's on the rear with factory size 17's on front?thanks

Re: handling with 315's?
 

I'm running Yoko 032Rs all around. The fronts are 275s on 17X9s. The rears are 315s on 17X10.5s.
The 315s in the 032s seem to be a bit on the small side for a 315-anyway they seem to work OK with the 10.5 width. It would most likely work better on a 11 inch wheel though. All in all, I'm happy with my set-up. About the only things I do with the car is a few autoxs and alot of play in the mountains. I might try a open practice this year but that will be about it. No road race stuff either so I'm running at a bit of a disadvantage compared to some others when it comes to experience. I am going to get two more 17X10.5s for the front and slap some 315s up front.

hows it take the turns compared to just your old 275 40,s?does the rear seem squishy or does it grip allitl more?

Go to TireRack.com, they have a spec. chart that shows the diameter of each tire. I think that my Yoko 315s were a bit taller than my Firestone Firehawk 275s. Most speedos are a bit conservative on the calibration, so when your speedo says you are going 60mph-you are actually going 57 or something. If they are just a smidge larger-great, it would fix the error. I wouldn't think it would be enough difference to throw things way off. Don't know for sure as I have 4.10s in the rear with no recalibration so it's off anyway.
