Running long gearing on mine helps with grip. I simply don't appear to have the probs most have with half the Power. However you need the Power to pull such gearing. I have a very tall 1st gear as well to increase Torque capacity of the box. Add- Proper Rear beam, Jag diff-loc, chassis connectors & decent coilovers with twin springs to stop squat + 235 wide 888's & you have grip even with 800+bhp & a GT42. You guys only seem to concentrate on the engine. Its a fast car you need not a fast engine they don't always go together.
