These car do not have a very sensitive Active Handling/Traction Control system so most concerns I keep reading about are overblown, IMO. Lots of people are running square tire set-ups, without issues. Even more guys are running small fronts and really big rears for roll or drag racing, without any problems.Unless your front tires are taller than the rears, I doubt you will experience any issues with your car's AH/TC.
l completely agree with you on this subject as well USA. l have read more than a few articles relating to this and they all have the same conclusion. Thank you
Street tires I can understand not liking the poke, race tires who cares because it's a functional thing.
C5Z rear wheels on the front with a 315 vs 295 vs 285 will have a varying degree of "poke". The silver car above looks like a 315-like poke. A narrower tier may not be so pronounced.
If anyone comes across this thread, if you are a fast driver driving at the limits frequently, a square setup WILL give you issues with ABS and hitting ICE mode due to the disparity between the front and rear diameters not having a difference (like intended stock). For this reason, I have had to delete my ABS system to have confidence in my brake pedal.
If you are a beginner to advanced weekend lapping guy, you shouldn't have issues. If you fall into a category above that, it may be wiser to stick with a staggered setup that conserves the stock sizing.

Just something to keep in mind
Your 315 square setup was not the issue. The C5 is notorious for "ice mode" it is a combination of steering angle/brake pedal/throttle and yaw sensor. The C5 is very sensitive to brake pressure spikes vs smooth application of brakes. To delete your ABS because of that was nuts to do. Playing with brake pad compounds and driving style could have easily kept you from Ice mode IMO.
Running a 315 square setup on 10.5" speediness may be THE MOST common wheel/tire combination to run. Below that may be a 275/295 combo or 295/305 or 295/315.
