Default LS1 edit help with ABS going off due to different tire sizes

Does LS1 Edit allow for correcting the mistake I made by getting tires fro front and rear that aren't close enough to the same hieght, I have 275/40 R17up front 295/35/r18 out back, my ABS functions alot of the time, gives some pedal feedback and hurts stopping. Can LS1 edit correct this? The corvette runs different tire hieghts front and rear, what does that have that I don't

So basically what you are telling me Texas is I need to get new tires that have closer diameters, Which means that 6mm on the radius is too much difference.

Yeah, going from 295/35 18 to a 295/30 18 was enough to trigger the TCS on my C5 over 40mph. (I run 265/35 18's on the front) I would say they have some tight tolerences. I've heard that the acceptable limit is 1" difference, but my experience tells me differently. Most people that run drag setups, turn off the TCS.

Best of luck.
