How upset will my ABS be if I run with 195/50R15 on the rear and 195/55R15 on the front?
ABS and different sized tyres?

Should still work but light might come on, I was running 55s on the back 45s on the front the light was on but worked 100% then when I got 45s all round light went off

It doesn't work when the lights on...
I had 185/65/14 and 185/55/14 without any issues...so you may get away with it.

ABS will only activate if it detects a significant wheel speed difference between wheels. This usually occurs just before a wheel locks up.
The very slight difference in tyre size won't be enough in terms of rolling speed to trigger the system.

Chances are it will bring on the light however the ABS SHOULD still work as it will detect that both axles are spinning at the same speed. You may find though that if you have EBD (which on a rallye you won't) that it upsets that a bit.

It should default to off when the light is on as a failsafe...
