2014 GT500 Wheels

Just installed a set of 2014 GT500 wheels on my 2013 Boss, that had 16 miles on them. They look great on my totally stock Boss. The GoodYear F1 Super Car tires really seem to grab hard. No issues with the TPMS sensors. Do I need to worry about the different sized rear tires P285/35 R20(the fronts are the same size)??? Do I need to get my Ford Dealer to change anything on the track key tune??? I will post some pictures later (yesterday was awful and my garage is to small to take a good picture) if anyone wants to see how sinister it looks.

I think you'll have a minimal error in your speedometer reading. You could always double check that with a gps...or gps app. for a smart phone.

pics please

are they the regular wheels or the svtpp wheels

as far as your ? , there are programs that will tell you what the difference in speedometer readings would be

I always wondered with the trackey installed if changing to a different wheel/tire size would affect anything because they ask when loading in trackey what size rear tire is on the car
 
Here are a few pictures. I real like the orignal wheels, but I don't want to damage them, so they are being kept safely stored for showing my car with orignal wheels. These are for driving and not worrying about what happens.
Hopefully the pictures are attached. I'm new to adding pictures.

Recently installed the same wheels and tires. If you want your speedo to be as accurate as possible you will need to visit the dealer and have the track key reprogrammed for the larger diameter rears, the revolutions per mile stock are 776 and with the larger diameter rears It worked out to be 749. Find an experienced "Track Key" Tech that has the Ford Racing departments phone number on speed dial because of the usual software issues. Local dealer charged me an hour labor for this.

Thanks for the info. Wouldn't the revs per mile be the other way around. Fewer revs with the larger tire.

I have a Canadian BOSS, and want to know where you got the info about our cars having the LS sway bars? Also what is the difference in rates?
Another Boss owner I met in the Toronto area bought a set of LS sway bars to put on his car (he is turning his 2013 SBY boss into a LS car) and when he went to get them installed he was told by the dealer that his car had the LS sized sway bars on the car (I believe is it 26mm, Standard boss is 25mm). My car measured the same.

Yes it should be reversed...it was late when I sent it. Corrected now.
