That looks like its gonna hurtNo the WRX is not different than most other manual Subarus: it has a central clutch pack and is 50/50 torque distribution by default. If you are outside the spec for rolling diameter, you are causing excessive wear to that clutch pack. It's overall pretty robust.
The STI is a whole different animal, as are the older turbo and H6 Legacy/Outback, which had the much-more-sophisticated VTD drive system. The STI is a step above that. Honda CR-V and RAV4 should have an "AWD" label instead of AWD. Honda got sued over their system performance, and most RAV4 drivers are too uninvolved to understand it shuts off at speed.
VW Golf platform is fun and I time-trialed and rallied two of them over several years.
Compared to the terminal understeer you get with FWD? Not so much....There's a reason why Subaru totally dominates US Rallying.
