I don't see why you would have ABS issues unless you only changed two tires, as long as all 4 match ABS should be fine, as will the AWD system. If you differ front and rear by 3% or more you may have AWD issues.

Since the 275/40/20 will fit on a lowered SHO, I see no reason to expect issue on a stock height car.

Much will depend on the wheel choice.  275 will not go on stock wheels from everything I have read.  What wheel are you looking to go to?

according to their spec sheet online the RS isn't made in a 255/45/20. have to stick with stock size or push your luck trying to mount a 275/40/20 on the stock rim

^thanks that's what i needed to know. Been tempted to try 275's on my 8.5" wheels but don't really think that'd be a great setup.

I'm not 100% sure, I believe 10". Will try to get a rough measurement tonight.

Kinda hard to see the stock wheels with the tires. How did that setup work out? Sidewall bulging?

Aren't 10" a bit wide for a 275?...BTW I love a 275/40 on the SHO...Grip monster....SHO bro I would put a 275 on a 8.5...Maybe a bit of a bulge but not bad...I have a 305 on my 9.5" mustang wheel...It's similar in terms of how much wider the tire is than the wheel.
