How wide are your tires? Switch to a 265/295 setup and see if that's enough grip.
Thanks for all the suggestions. I'm running the stock sizes of 245/40-18 in front and 265/40-18 rear, as I noted with Advan Neova AD08s. They are way better in the dry than the PS-2s, but not in the wet.
If I switch to the 265/295, can I stay with the 18" wheels and 40 profile without any problems? The tires will not extend beyond the wheel well?
I should also note I have the Dinan Stage III suspension--the camber plates and springs do make a big difference--the larger front antisway bar not much on the street, but some improvement at autocross.
