Im very happy with 4.3 diff improved my lap times at Symmons plains The gearbox ratios work much better pulling hard in 5th into coca cola corner And on Hillclimbs ratios work well and launches a dream last Hillclimb i was matching the targa winning evo10 with launch control to first timing mark And it still cruises happily in 6th on 1700 revs for 110 kph
