   Depending on your driving style 30/60 or 30/30 or as above, 45/45 may suit.
   
   45/45 is a good "middle of the road" setting.
   
   I would prefer a 30 degree throttle ramp on track if I was that way orientated, but would like it well behaved on lift-off, so would have either 45 or more likely 60 coast ramp. so 30/60 would be my preference.
   
   Edit to add: I actually have 45/45 as it's an off the shelf setting - but I have a road car not a track car.

   30/60 setting is more of a rally stage setting, on the track it would bang in and not drive well at all, ashley taylor i believe it was i was talking to about ramp rates and he was saying about a 205 he drove at cadwell with a 30/60 ramp and it come in like a 125 express

   Yeah 30 is aggressive for sure but on throttle and on track I'd have thought it would be ok - be more concerned with the coast ramp. (Remember: I'm purely speculating as I don't drive on track!).
   
   What I can tell you is when I got my diff first fitted it was specc'd completely incorrectly for the car (not by me I might add...) and was 30/30. On a road car was a fucking nightmare...

   I think you would find 45/45 the ideal setup. Maybe email Dave Mac Propshafts (who make the gripper diff) and ask their advice for your situation?

    Ok! I hope your happy with it. If you don't like it, it's no real hassle to change plates.

    give the manufacturer or your dealer a ring.
