I just installed the CARB tuned C38 Jackson Racing supercharger on my BRZ, but now I'm having traction issues during hard acceleration in 1st gear from 5000 to 7000 rpms. The tires will break free and the traction control light will blink.

I'm running Bridgestone Potenza S-04 Pole Position 215-45/17 on stock rims.

Was thinking of getting stickier tires to help..
Dunlop Direzza ZII Star Spec. (or whatever you may suggest)

Question is, what size?
215-45/17, 225-45/17, 245-40/17?

My requirements: use the stock rims, stay within 2% of the stock diameter, have the maximum grip for hard acceleration, can be used for autoX and daily driving.
