My swift GTI racecar has a Suzitech built locked 4.1 gearbox, but i removed it yesterday as its a major, major handful to steer/drive at low speeds and the steering grabs badly to one side due to it. I have decided that its not what i want when i go racing at track days. I prefer easy steering driving. A locked diff for FWD application is crazy. You need hands like hulk just to steer with them.


Question is, what will be better:
High revs in gears = Low overall speed (genuine GTI gearbox) OR
CINO gearbox = Able to reach more speed overall. (longer gear ratios).


Would a CINO gearbox be good for twists and turns at a racetrack, or will it be like bogging down, slow to pickup speed.

Just swap out the locked diff for an LSD. Problem solved.

I would go for acceleration over top speed as you use acceleration more out of the corners than you do top speed. Small engine means revs for power so you need to keep the engine within its powerband all the time for maximum performance. This is done with a close ratio gearbox.

Or install power steering like most people with a CIG locker. ;)

or simply stop complaining and hit the Gym for some arm work :D

There are trade offs, and on the track you shouldn't notice it.

If the steering is pulling to one side are you sure you haven’t got a broken CV?

As above. Keep the locker and get stronger. Once you're on the track it's not that noticeable

I have a suzuki plate LSD. It is brilliant. My son found it heavy...I didn't find it too bad but the next day the shoulders ached....so we are going to put an electric power steer in on low assist....I have one from the days of offroad buggies that I never fitted.
