To me, I find it better to work on the car setup, rather than to go to the extent of going to 35/32R for traction. I was running the NTC3 for the past 3 years on a cemented carpark track, tire wear was high, traction is not too great but OK. Traction wise, 37 is good, 35 is the best; but tire wear is a pain. We managed to found out the best combination of 37F 40R for the track (which caters more to a rubber tire track), complementing the factors of tire wear, traction and the handling with the car setup; WITHOUT any compensation on speed.
It could all be the one-way you're using. Top drivers over here tried the one-way on the car, but still they find the diff to be THE "THING" for the NTC3. You could always work on the diff tightness to gain steering up front, while not sacrificing the rear traction.
But if you insisted on using the one-way, it helps to increase the rear traction by
1) Stiffening the front antiroll bar/front shocks
2) Increase rear droop
3) Lower rear roll center(more horizontal camber link)
