I was reluctant to buy go fast bits until recently when I decided to swap the rear sway bar from 13 to 20 mm (resulting in a drastic reduction on body roll).
So, now I wonder how much of an improvement I should expect if I drop some money on
- Kartboy shifter
- Kartboy shifter bushings
- Synthetic gear oil in the transmission
- Synthetic gear oil in the rear diff
For each mod of the four above those who did it could you tell me on the scale of something like "Oh my gawd, I can't believe it's so much better" "It's noticeably better" "Not much of a difference" "Worse"
what I'm likely get bung for buck wise. I just hate the feel of 5sp shifter on my impreza.
Also, did anyone install STI oem springs or spring/strut combo and can comment how that affected your ability to scrub on the improvements erected by the civil engineers around parking lots and their entrances ? (Rain gutters and other versions of speed bumps I mean)
Thank you!
