1.Im parting out all my mods and going back to stock.
2. Yes it was installed in my car for over a year. See number 1.
3. Increasing the diameter of the rear sway bar will increase oversteer in any car.
bonus: stock rear sway 16.5mm
Si rear sway 18.5mm
Type R rear sway 20.5mm
Yes I had the airbag light on the dash. It didnāt bother me tbh. The connector for the passenger sensor isnāt the same in the hatch. Might be the same on the Touring. Also the seats are heated so they will work if your car has the heated seats.
