Has anyone run all the same size wheels and tires.
I saw someone selling four wheels all the same size,with four tires all the same size(diameter not width) and could not get an answer how they worked.I was told you need to keep the one inch differential from front to back,but there has got to be a way to make it work right?

Outside tire diameter is all that matters

If the tire height is the same front to rear the computer is going to get all sorts of mad.
It has 5 speed sensors. one in the diff and one at each wheel. If you break the split front to rear it is going to have a hard time figuring front and rear speeds and think it is spinning a tire or trying to lock one up and start to put the car in active handling mode. ABS calibrations will also be off.
You could do it, but you would have to completely turn off active handling and traction control every time you drove it, even then not sure how bad it would throw off the ABS calibration.
Some of the track guys will change heights and keep some stagger front to rear and the ABS is 'ok' but again AH and TC have to be off.

i plan to have AH and TCS off anyway, but am worried about ABS rearing its head more than it should. or even worse at unsafe times on track.

Short answer is you must keep close to the stock stagger ratio or the AH will go nuts even if it's off. You can run taller or shorter tires but you have to stay close to stock stagger.
If you post your planned tires in the auto cross section you'll get good answers, it's been well researched over there.
