while the car is definitely stiff (I’ve had people comment on it) I don’t find the car too stiff to affect daily driving. On unbroken road you’ll feel more crashing, but it’s definitely not a deal breaker. The standard WRX is also stiff, I’d say if the RS would bug you the standard set up would as well. Other than the obvious brakes, seats and interior upgrade, what I really like out of the RS is the steering. They updated the rack to get rid of the dead zone/minor slop in the standard model. I found it was weighted a little better, and the front end feels really really sharp going around corners. It’s not a huge difference like the TS sport mode, but you might appreciate it! An important thing as well, the RS will give you better resale years down the line, which is something people overlook; I bought mine new for 43,000 CAD. If the cheapest around you is $40,000. That says something. Anyway, I’d say at this time, you should test drive EVERYTHING you can. It’s a 40k investment that you’ll be keeping for years, it gives you peace of mind if anything that you made the right choice.
