More than likely, your slower turn in is caused by a change in wheel offset when you went to the 17's. This changed your scrub radius, which in turn effected your turn in. I know this means nothing to most people who don't have experience with suspension setup on race cars, so rather than try to explain the scrub triangle and its effects, if you are interested, google "ackerman angle, steering axis inclination, and scrub radius" and read up. Otherwise, just know its probably your wheel offset that is effecting your turn in most.
