    I posted this under the f430 model thread but it was suggested I try here...

    I just ordered a new set of wheels and tires for my f430 through a local performance shop who assured me that everything will fit.

    Wheels:ForgeLine ZX3R
    Front: 19x8.5 (same size as stock wheels)
    Rear: 19x10.5 (same size as stock wheels)

    Tires: Hoosier R6
    Front: 235/35, OD=25.6" vs stock 225/35, OD=25.1"
    Rear: 295/30, OD=26.1" vs stock 285/35, OD= 26.7"

    Question: With the overall diameter of the new front tires being .5" larger than stock and the OD of the new rear tires being .6" smaller than stock, isn't that going to screw up my ABS, Track Control, and Stability Control? I would think the sensors would sense the rear wheels are slipping since they are rotating faster than the stock wheels due to the smaller diameter size and vice versa with the front wheels. I imagine this will also screw up my odometer, speedometer, and tach readings. For that matter, does the rear or front tires drive the speedometer, odometer, and tach? The Pilot Cups (235/35,305/30) are a bit closer to stock OD size (25.5" and 26.3") but my guy told me the performance is not up to par with the Hooziers.

    Any ideas? Thanks in advance.
