Track tires - Width issue?
I'm looking to replace my current tires at some point in the next year with some more track oriented tires ( Hankook, Toyo's, , etc) I have Sport Designs wheels with 285/30 -18 and 225/40-18 Sumitomos now. It seems to me that this set up is more prone to understeer then the stock 265/225 set up. I don't tknow if I can get wider tires in the front to fit( i.e. 235 or 245).
So it the better set up 265/225 for the track?

I have 235 and 295's on 18 turbo twists. You be fine running the cuurent sizes you have. I really don't think you notice understeer or oversteer unless you are driving club races.

Thanks that is good to know. I think for my first set i'm go to try the Hankook R-S3
Looks like I will have to run 245/40-18 and 285/35-18 if I want those tires.

225/285 should be fine
265 is the rear makes the rear end very loose. If you used to it then switching to 285's it'll feel like having a little more rear end grip. To you it may feel like understeer but you just arn't going fast enough yet or not trail braking.
265's and I am sideways coming into the corner and then straighten it out as I power out. Fun but slower.

Just make sure that your tire to suspension clearance is good with your specific wheel/tire combo. When I changed to 997 wheels I had less clearance up front and ended up having to go down to 225. Now that I've changed out the suspension I have much more clearance and could easily increase the front width.
PS--This also assumes that you can mount these wider tires on your wheels. There are physical limits during the mounting process and you'll reach a limit where you get less traction for a wider tire if your wheel width isn't a good match.
