There’s no need to change diff gears.

Headers, intake and tune would be a better package than diff gears and a tune and the price wouldn’t be too different.

GT Performance in Melbourne have done good work for a long time.

Have you tried driving it in sport +? I thought it made quite a lot of difference in the manual, takes it from what feels like a 6 second plus car to what feels like a 5 second car. I only realised that after I had the car nearly a year, lol.
