Will,when i first did my GT5 conversion i went with Budnik  18X10 and 18X13 wheels, i went with 5 inch front and 5.5 inch rear backspacing.HOWEVER,my brakes are the Wilwoods that have the hats on the OUTSIDE of the hub which moves the wheel outboard .5 inches.So if i had stock style hats that were on the inside of the hub my backspacing would have been 4.5 front,5 inch rear.My tires were 285/30/18 and 345/30/18 pilot sport cup competions.
In my opinion the 245 tire you mentioned is too narrow for the 10 rim.It should be a 275.
I have since changed wheels and tires and i now have Kinesis wheels and Toyo R888 tires 285/30/18 and 335/30/18.The Kinesis wheels are much lighter,and the Toyos grip is a lot better as well.
A couple of notes,a factory GT5  has a .5 inch wheel spacer,so keep that in mind if you want to use factory GT5 backspacing specs.A GT5S has a different back spacing than the GT4/GT5 because the flares are narrower.
You MUST mock up the flares you purchased,and measure the backspacing on your car! The flares you bought  might vary in width from the factory or from other vendors.Your car may vary as well.It does not matter why it may vary,just play it safe and measure.
Most important of all,NEVER total up your receipts of what you have spent!It dont matter!Do you like the car?If you do,who cares how much the cost was?Enjoy it,drive it.
I have owned a lot of cars and every one i have changed/modified.There are problems that come up with vendors or the parts themselves,but in the end its worth it. Hands down the Pantera is the best!The Pantera has the best of all worlds.Once properly set up,it goes,turns and stops,and looks the best of any car out there.Granted its my opinion,but im right! So when problems occur(and they will),step back,relax,dont talk about selling the car,or you will regret it later.It seems like every time i drive my car i run into someone who used to own or knew someone who had a Pantera and they always have a longing in there voice.Dont become one of them..........
