Noisy (tapping) injector, getting fixed at present.
So much torque pulls hard any gear any RPM.
Back end twitchy in the wet.
I have a 1998 Impreza L and have never had any problems with the rear end being "twitchy". I have use summer tires when there is no snow on the ground and do fine.
To the above comment: Impreza L not twitchy?
Probably as the STi has much more power and the ability to exploit it than your 'L.'
Not being funny but buy a real scooby Mate.
